0.05) between wild (AR = 4.651), semi-cultivated (AR = 5.091) and cultivated (AR = 5.132) populations of C. taliensis, which suggested that the genetic background of long-lived woody plant was not easy to be changed, and there were moderate high gene flow between populations. However, there was a significant difference (P < 0.05) between wild (AR = 5.9) and cultivated (AR = 7.1) populations distributed in the same place in Yun county, Yunnan province, which may result from the hybridization and introgression of species in the tea garden and anthropogenic damages to the wild population. The hypothesis of hybrid origin of C. grandibracteata was tested by morphological and microsatellites analyses. Compared with other species, the locules in ovary of C. grandibracteata are variable, which showed a morphological intermediate and mosaic. Except one private allele, Ninety-nine percent alleles of C. grandibracteata were shared with these of C. taliensis and C. sinensis var. assamica. And C. grandibracteata was nested in the cluster of C. taliensis in the UPGMA tree. Conclusively, our results supported the hypothesis of hybrid origin of C. grandibracteata partly. The speciation of C. grandibracteata was derived from hybridization and asymmetrical introgression potentially. It is possible that C. taliensis was one of its parents, but it still needs more evidences to prove that C. sinensis var. assamica was another parent.","jscount":"1","jsurl":"/simple-search?field1=all&rpp=10&accurate=false&advanced=false&sort_by=2&isNonaffiliated=false&search_type=-1&query1=leaf%2Btrait&order=desc&&fq=dc.project.title_filter%3ACamellia%5C+taliensis%5C+%5C%28W.%5C+W.%5C+Smith%5C%29%5C+Melchior%2C%5C+a%5C+member%5C+of%5C+Camellia%5C+sect.%5C+Thea%2C%5C+is%5C+an%5C+indigenous%5C+species%5C+in%5C+local%5C+natural%5C+forest%5C+and%5C+has%5C+a%5C+long%5C+cultivative%5C+history%5C+in%5C+western%5C+Yunnan%5C+and%5C+its%5C+neighborhood%2C%5C+where%5C+the%5C+domestications%5C+of%5C+this%5C+species%5C+in%5C+different%5C+historical%5C+periods%5C+and%5C+in%5C+different%5C+ways%5C+can%5C+be%5C+found.%5C+C.%5C+taliensis%5C+is%5C+an%5C+important%5C+contributor%5C+to%5C+the%5C+formations%5C+of%5C+tea%5C+landraces%5C+by%5C+hybridization%5C+and%5C+introgression.%5C+In%5C+the%5C+present%5C+study%2C%5C+14%5C+microsatellite%5C+loci%5C+screened%5C+from%5C+37%5C+loci%5C+were%5C+used%5C+to%5C+explore%5C+the%5C+genetic%5C+diversity%5C+about%5C+this%5C+species%5C+with%5C+579%5C+samples%5C+from%5C+25%5C+populations%5C+%5C%2816%5C+wild%5C+populations%2C%5C+4%5C+semi%5C-cultivated%5C+populations%5C+and%5C+5%5C+cultivated%5C+populations%5C%29.%5C+At%5C+the%5C+same%5C+time%2C%5C+the%5C+potential%5C+hybrid%5C+speciation%5C+of%5C+C.%5C+grandibracteata%2C%5C+was%5C+investigated%5C+using%5C+39%5C+individuals%5C+from%5C+2%5C+populations%2C%5C+along%5C+with%5C+C.%5C+taliensis%5C+and%5C+C.%5C+sinensis%5C+var.%5C+assamica%5C+%5C%2883%5C+individuals%5C+from%5C+4%5C+populations%5C%29%5C+by%5C+the%5C+same%5C+microsatellite%5C+markers.%5C+C.%5C+taliensis%5C+had%5C+a%5C+moderate%5C+high%5C+level%5C+of%5C+genetic%5C+diversity%5C+%5C%28A%5C+%3D%5C+14.3%2C%5C+Ne%3D%5C+5.7%2C%5C+HE%5C+%3D%5C+0.666%2C%5C+I%5C+%3D%5C+1.753%2C%5C+AR%5C+%3D%5C+7.2%2C%5C+PPB%5C+%3D%5C+100%25%5C%29.%5C+This%5C+may%5C+result%5C+from%5C+several%5C+factors%5C+including%5C+K%5C-strategy%2C%5C+genetic%5C+background%2C%5C+gene%5C+flow%5C+between%5C+populations%2C%5C+hybridization%5C+and%5C+introgression%5C+among%5C+species.%5C+Between%5C+wild%5C+populations%5C+of%5C+C.%5C+taliensis%2C%5C+the%5C+gene%5C+flow%5C+was%5C+moderate%5C+high%5C+%5C%28Nm%5C+%3D%5C+1.197%5C%29%2C%5C+and%5C+genetic%5C+variation%5C+was%5C+less%5C+than%5C+20%25%5C+%5C%28GST%5C+%3D%5C+0.147%2C%5C+FST%5C+%3D%5C+0.173%5C%29%2C%5C+which%5C+was%5C+similar%5C+to%5C+other%5C+research%5C+results%5C+of%5C+long%5C-lived%5C+woody%5C+plants%2C%5C+and%5C+reflected%5C+the%5C+genetic%5C+structure%5C+of%5C+its%5C+ancestry%5C+to%5C+same%5C+extent.%5C+There%5C+was%5C+a%5C+high%5C+significant%5C+correlation%5C+between%5C+geographic%5C+distance%5C+and%5C+Nei%E2%80%99s%5C+genetic%5C+distance%5C+%5C%28r%5C+%3D%5C+0.372%2C%5C+P%5C+%3D%5C+0.001%5C%29%5C+of%5C+populations%2C%5C+which%5C+accorded%5C+with%5C+isolation%5C+by%5C+distance%5C+model.%5C+Inferring%5C+from%5C+Bayesian%5C+clustering%5C+of%5C+genotypes%2C%5C+all%5C+individuals%5C+of%5C+C.%5C+taliensis%5C+were%5C+divided%5C+into%5C+two%5C+groups%2C%5C+conflicting%5C+with%5C+the%5C+result%5C+based%5C+on%5C+Nei%E2%80%99s%5C+genetic%5C+distance%5C+and%5C+real%5C+geographic%5C+distribution%2C%5C+which%5C+suggested%5C+there%5C+were%5C+heavy%5C+and%5C+non%5C-random%5C+influences%5C+by%5C+human%5C+practices.%5C+According%5C+to%5C+allelic%5C+richness%2C%5C+there%5C+were%5C+no%5C+significant%5C+differences%5C+%5C%28P%5C+%3E%5C+0.05%5C%29%5C+between%5C+wild%5C+%5C%28AR%5C+%3D%5C+4.651%5C%29%2C%5C+semi%5C-cultivated%5C+%5C%28AR%5C+%3D%5C+5.091%5C%29%5C+and%5C+cultivated%5C+%5C%28AR%5C+%3D%5C+5.132%5C%29%5C+populations%5C+of%5C+C.%5C+taliensis%2C%5C+which%5C+suggested%5C+that%5C+the%5C+genetic%5C+background%5C+of%5C+long%5C-lived%5C+woody%5C+plant%5C+was%5C+not%5C+easy%5C+to%5C+be%5C+changed%2C%5C+and%5C+there%5C+were%5C+moderate%5C+high%5C+gene%5C+flow%5C+between%5C+populations.%5C+However%2C%5C+there%5C+was%5C+a%5C+significant%5C+difference%5C+%5C%28P%5C+%3C%5C+0.05%5C%29%5C+between%5C+wild%5C+%5C%28AR%5C+%3D%5C+5.9%5C%29%5C+and%5C+cultivated%5C+%5C%28AR%5C+%3D%5C+7.1%5C%29%5C+populations%5C+distributed%5C+in%5C+the%5C+same%5C+place%5C+in%5C+Yun%5C+county%2C%5C+Yunnan%5C+province%2C%5C+which%5C+may%5C+result%5C+from%5C+the%5C+hybridization%5C+and%5C+introgression%5C+of%5C+species%5C+in%5C+the%5C+tea%5C+garden%5C+and%5C+anthropogenic%5C+damages%5C+to%5C+the%5C+wild%5C+population.%5C+The%5C+hypothesis%5C+of%5C+hybrid%5C+origin%5C+of%5C+C.%5C+grandibracteata%5C+was%5C+tested%5C+by%5C+morphological%5C+and%5C+microsatellites%5C+analyses.%5C+Compared%5C+with%5C+other%5C+species%2C%5C+the%5C+locules%5C+in%5C+ovary%5C+of%5C+C.%5C+grandibracteata%5C+are%5C+variable%2C%5C+which%5C+showed%5C+a%5C+morphological%5C+intermediate%5C+and%5C+mosaic.%5C+Except%5C+one%5C+private%5C+allele%2C%5C+Ninety%5C-nine%5C+percent%5C+alleles%5C+of%5C+C.%5C+grandibracteata%5C+were%5C+shared%5C+with%5C+these%5C+of%5C+C.%5C+taliensis%5C+and%5C+C.%5C+sinensis%5C+var.%5C+assamica.%5C+And%5C+C.%5C+grandibracteata%5C+was%5C+nested%5C+in%5C+the%5C+clust

a field trip at a brule in Shangri-La, a mixed population of Ligularia Cass. was found, which including L. subspicata (Bur. et Franch.) Hand.-Mazz., L. nelumbifolia (Bur. et Franch.) Hand.-Mazz., L. tongolensis (Franch.) Hand.-Mazz., L. cymbulifera (W.W.Smith) Hand.-Mazz., L. lingiana S.W.Liu, and also some individuals morphologically intermediate between L. subspicata and L. nelumbifolia. Hence, these intermediate individuals were preliminarily assumed as natural hybrids of the two Ligularia. According to their morphology, they’re assumed to form hybrids A and B. Through careful comparison of specimens in herbarium and those we collected, the inflorescence of putative hybrid A is close to L. nelumbifolia, but the shape of laminae are intergradation of L. subspicata and L. nelumbifolia; overall morphology of putative hybrids B is similar to L. nelumbifolia, but inflorescence color is as same as L. subspicata. Compared to L. nelumbifolia (39%) and L. subspicata (36.8%), the germination rate of putative hybrid B (45.7%) slightly higher than the two; but that of hybrid A is extraordinarily low (0.3%). One possible interpretation of the low rate is hybridization. 60 individuals were collected, including putative parents, other 4 species of Ligularia nearby, putative hybrid A and B. They were all direct sequenced of four cpDNA fragments, and direct sequenced or cloning sequenced of nrDNA ITS4-5. The results support that L. nelumbifolia and L. subspicata are parents of putative hybrid A, and the majority female parent is L. subspicata, L. vellerea may also be involved in the hybridization in some degree; the nuclear sequences of putative hybrid B have no superposition, and its chloroplast DNA sequences are identical with L. nelumbifolia, so putative hybrid B could not be hybrid; and there are backcross individuals exist among the putative parent L. subspicata. NewHybrids analysis of ISSR markers indicated that, the individuals of putative hybrid A are almost L. nelumbifolia and L. subspicata F1 hybrid generation (10/11), only 1/11 possibly backcross or other forms; all individuals of hybrid B are L. nelumbifolia; except one individual of L. subspicata as backcrossed, the other parent individuals are 100% reliable. This study focused on molecular evidence, complemented by ecological, reproductive and other characteristics, we demonstrated that the morphologically intermediate individuals’ origin, and the probability of belonging to each parental or hybrid class. And concluded that L. nelumbifolia and L. subspicata are the parents of putative hybrid A, L. vellerea may also be involved in the hybridization in some degree, hybrids mainly are the first generation, a few individuals may be involved in backcross, and most probably backcross with L. subspicata according to the anthesis, while the assumption of hybrid B is not supported.","jscount":"1","jsurl":"/simple-search?field1=all&rpp=10&accurate=false&advanced=false&sort_by=2&isNonaffiliated=false&search_type=-1&query1=leaf%2Btrait&order=desc&&fq=dc.project.title_filter%3ADuring%5C+a%5C+field%5C+trip%5C+at%5C+a%5C+brule%5C+in%5C+Shangri%5C-La%2C%5C+a%5C+mixed%5C+population%5C+of%5C+Ligularia%5C+Cass.%5C+was%5C+found%2C%5C+which%5C+including%5C+L.%5C+subspicata%5C+%5C%28Bur.%5C+et%5C+Franch.%5C%29%5C+Hand.%5C-Mazz.%2C%5C+L.%5C+nelumbifolia%5C+%5C%28Bur.%5C+et%5C+Franch.%5C%29%5C+Hand.%5C-Mazz.%2C%5C+L.%5C+tongolensis%5C+%5C%28Franch.%5C%29%5C+Hand.%5C-Mazz.%2C%5C+L.%5C+cymbulifera%5C+%5C%28W.W.Smith%5C%29%5C+Hand.%5C-Mazz.%2C%5C+L.%5C+lingiana%5C+S.W.Liu%2C%5C+and%5C+also%5C+some%5C+individuals%5C+morphologically%5C+intermediate%5C+between%5C+L.%5C+subspicata%5C+and%5C+L.%5C+nelumbifolia.%5C+Hence%2C%5C+these%5C+intermediate%5C+individuals%5C+were%5C+preliminarily%5C+assumed%5C+as%5C+natural%5C+hybrids%5C+of%5C+the%5C+two%5C+Ligularia.%5C+According%5C+to%5C+their%5C+morphology%2C%5C+they%E2%80%99re%5C+assumed%5C+to%5C+form%5C+hybrids%5C+A%5C+and%5C+B.%5C+Through%5C+careful%5C+comparison%5C+of%5C+specimens%5C+in%5C+herbarium%5C+and%5C+those%5C+we%5C+collected%2C%5C+the%5C+inflorescence%5C+of%5C+putative%5C+hybrid%5C+A%5C+is%5C+close%5C+to%5C+L.%5C+nelumbifolia%2C%5C+but%5C+the%5C+shape%5C+of%5C+laminae%5C+are%5C+intergradation%C2%A0of%5C+L.%5C+subspicata%5C+and%5C+L.%5C+nelumbifolia%5C%3B%5C+overall%5C+morphology%5C+of%5C+putative%5C+hybrids%5C+B%5C+is%5C+similar%5C+to%5C+L.%5C+nelumbifolia%2C%5C+but%5C+inflorescence%5C+color%5C+is%5C+as%5C+same%5C+as%5C+L.%5C+subspicata.%5C+Compared%5C+to%5C+L.%5C+nelumbifolia%5C+%5C%2839%25%5C%29%5C+and%5C+L.%5C+subspicata%5C+%5C%2836.8%25%5C%29%2C%5C+the%5C+germination%5C+rate%5C+of%5C+putative%5C+hybrid%5C+B%5C+%5C%2845.7%25%5C%29%5C+slightly%5C+higher%5C+than%5C+the%5C+two%5C%3B%5C+but%5C+that%5C+of%5C+hybrid%5C+A%5C+is%5C+extraordinarily%5C+low%5C+%5C%280.3%25%5C%29.%5C+One%5C+possible%5C+interpretation%5C+of%5C+the%5C+low%5C+rate%5C+is%5C+hybridization.%5C+60%5C+individuals%5C+were%5C+collected%2C%5C+including%5C+putative%5C+parents%2C%5C+other%5C+4%5C+species%5C+of%5C+Ligularia%5C+nearby%2C%5C+putative%5C+hybrid%5C+A%5C+and%5C+B.%5C+They%5C+were%5C+all%5C+direct%5C+sequenced%5C+of%5C+four%5C+cpDNA%5C+fragments%2C%5C+and%5C+direct%5C+sequenced%5C+or%5C+cloning%5C+sequenced%5C+of%5C+nrDNA%5C+ITS4%5C-5.%5C+The%5C+results%5C+support%5C+that%5C+L.%5C+nelumbifolia%5C+and%5C+L.%5C+subspicata%5C+are%5C+parents%5C+of%5C+putative%5C+hybrid%5C+A%2C%5C+and%5C+the%5C+majority%5C+female%5C+parent%5C+is%5C+L.%5C+subspicata%2C%5C+L.%5C+vellerea%5C+may%5C+also%5C+be%5C+involved%5C+in%5C+the%5C+hybridization%5C+in%5C+some%5C+degree%5C%3B%5C+the%5C+nuclear%5C+sequences%5C+of%5C+putative%5C+hybrid%5C+B%5C+have%5C+no%5C+superposition%2C%5C+and%5C+its%5C+chloroplast%5C+DNA%5C+sequences%5C+are%5C+identical%5C+with%5C+L.%5C+nelumbifolia%2C%5C+so%5C+putative%5C+hybrid%5C+B%5C+could%5C+not%5C+be%5C+hybrid%5C%3B%5C+and%5C+there%5C+are%5C+backcross%5C+individuals%5C+exist%5C+among%5C+the%5C+putative%5C+parent%5C+L.%5C+subspicata.%5C+NewHybrids%5C+analysis%5C+of%5C+ISSR%5C+markers%5C+indicated%5C+that%2C%5C+the%5C+individuals%5C+of%5C+putative%5C+hybrid%5C+A%5C+are%5C+almost%5C+L.%5C+nelumbifolia%5C+and%5C+L.%5C+subspicata%5C+F1%5C+hybrid%5C+generation%5C+%5C%2810%5C%2F11%5C%29%2C%5C+only%5C+1%5C%2F11%5C+possibly%5C+backcross%5C+or%5C+other%5C+forms%5C%3B%5C+all%5C+individuals%5C+of%5C+hybrid%5C+B%5C+are%5C+L.%5C+nelumbifolia%5C%3B%5C+except%5C+one%5C+individual%5C+of%5C+L.%5C+subspicata%5C+as%5C+backcrossed%2C%5C+the%5C+other%5C+parent%5C+individuals%5C+are%5C+100%25%5C+reliable.%5C+This%5C+study%5C+focused%5C+on%5C+molecular%5C+evidence%2C%5C+complemented%5C+by%5C+ecological%2C%5C+reproductive%5C+and%5C+other%5C+characteristics%2C%5C+we%5C+demonstrated%5C+that%5C+the%5C+morphologically%5C+intermediate%5C+individuals%E2%80%99%5C+origin%2C%5C+and%5C+the%5C+probability%5C+of%5C+belonging%5C+to%5C+each%5C+parental%5C+or%5C+hybrid%5C+class.%5C+And%5C+concluded%5C+that%5C+L.%5C+nelumbifolia%5C+and%5C+L.%5C+subspicata%5C+are%5C+the%5C+parents%5C+of%5C+putative%5C+hybrid%5C+A%2C%5C+L.%5C+vellerea%5C+may%5C+also%5C+be%5C+involved%5C+in%5C+the%5C+hybridization%5C+in%5C+some%5C+degree%2C%5C+hybrids%5C+mainly%5C+are%5C+the%5C+first%5C+generation%2C%5C+a%5C+few%5C+individuals%5C+may%5C+be%5C+involved%5C+in%5C+backcross%2C%5C+and%5C+most%5C+probably%5C+backcross%5C+with%5C+L.%5C+subspicata%5C+according%5C+to%5C+the%5C+anthesis%2C%5C+while%5C+the%5C+assumption%5C+of%5C+hybrid%5C+B%5C+is%5C+not%5C+supported."},{"jsname":"ECOLPIN[AGL2011-24296]","jscount":"1","jsurl":"/simple-search?field1=all&rpp=10&accurate=false&advanced=false&sort_by=2&isNonaffiliated=false&search_type=-1&query1=leaf%2Btrait&order=desc&&fq=dc.project.title_filter%3AECOLPIN%5C%5BAGL2011%5C-24296%5C%5D"},{"jsname":"EU

scent is a very important character in rose breeding. However, many of 25,000 rose cultivars have no scent or weak scent. The tea scent of modern roses mainly originated from Rosa odorata (Andrews) Sweet, which is one of the most important ancestors of modern cultivated roses and the very important rose breeding resource. Due to the land expanding, habitat fragmentation and so on, R. odorata has been listed as an endangered species in ‘Chinese Plant Red Data Book—Rare and Endangered Plants’ and as the third-category endangered species in ‘Chinese Rare and Endangered Protective Plants List’. Therefore, it is urgent to protect this species and studying the conservation genetics of R. odorata is essentially important to work out a strategy of conservation.R. odorata comprises three double-petaled varieties (R. odorata var. odorata, R. odorata var. erubescens, and R. odorata var. pseudindica) and one single-petaled variety (R. odorata var. gigantea). The taxonomy of the three double-petaled varieties of R. odorata has been disputed for a long time. They have been treated as intraspecific taxa of R. odorata var. gigantea or R. chinensis by different botanist. According to the morphological analyses, Hurst (1941) inferred that R. odorata var. odorata was the hybrid between R. odorata var. gigantea and R. chinensis. Therefore, in order to clarify the right protective units, two single-copy nuclear genes (GAPDH and ncpGS), together with two plastid loci (trnL-F and psbA-trnH) were applied to study the hybrid origin of the three double-petaled varieties and to identify their possible parents. Our data suggested the hybrid origin of the three double-petaled varieties. We inferred that R. odorata var. gigantea could be the maternal parent and R. chinensis cultivars be the paternal parent. It is strongly suggested that the conservation of R. odorata is the conservation of its wild type, R. odorata var. gigantea. We first applied seven microsatellite loci (SSR) coupled with a single-copy nuclear gene GAPDH to study the genetic diversity and genetic structure of R. odorata var. gigantea. The main results are shown as follows:1. Genetic diversity：R. odorata var. gigantea maintains high degree of genetic diversity within and among populations (SSR: HT = 0.738, HS = 0.569, AR = 5.583, PPB = 97.35%, I = 1.703; GAPDH: HT = 0.739, HS = 0.540). We inferred that, outcrossing, long-lived tree species, clonal reproduction and general intraspecies hybridization between individuals, have contributed to the high degree of genetic diversity in R. odorata var. gigantea.2. Genetic differentiation and genetic structure：There was some degree of genetic differentiation among populations (SSR: GST = 0.229, FST = 0.240; GAPDH: GST = 0.269). The geographic isolation limited the dispersal of pollen or seeds, which resulted in the limitation of gene flow (Nm = 0.792). Then, the limited gene flow should be accounted for the genetic differentiation. Both the results of SSR data and haplotype analysis of GAPDH indicated that, the studied populations were divided into two distinct groups by Honghe River. These two groups showed significant genetic differentiation and represented two separate evolutionary lineages, which should be recognized as two evolutionary significant units (ESUs) for conservation concerns.3. Conservation of R. odorata：R. odorata var. gigantea has been listed in the ‘National Key Protective Wild Species List (II)’. Therefore, the conservation of this species is urgent. We inferred that, the main endangered reasons should be the habitat fragmentation and the reduction of populations and individuals per population resulted from environmental damage and human activities. We proposed that the strategy of in-situ conservation combining with ex-situ conservation should be carried out.","jscount":"1","jsurl":"/simple-search?field1=all&rpp=10&accurate=false&advanced=false&sort_by=2&isNonaffiliated=false&search_type=-1&query1=leaf%2Btrait&order=desc&&fq=dc.project.title_filter%3AFlower%5C+scent%5C+is%5C+a%5C+very%5C+important%5C+character%5C+in%5C+rose%5C+breeding.%5C+However%2C%5C+many%5C+of%5C+25%2C000%5C+rose%5C+cultivars%5C+have%5C+no%5C+scent%5C+or%5C+weak%5C+scent.%5C+The%5C+tea%5C+scent%5C+of%5C+modern%5C+roses%5C+mainly%5C+originated%5C+from%5C+Rosa%5C+odorata%5C+%5C%28Andrews%5C%29%5C+Sweet%2C%5C+which%5C+is%5C+one%5C+of%5C+the%5C+most%5C+important%5C+ancestors%5C+of%5C+modern%5C+cultivated%5C+roses%5C+and%5C+the%5C+very%5C+important%5C+rose%5C+breeding%5C+resource.%5C+Due%5C+to%5C+the%5C+land%5C+expanding%2C%5C+habitat%5C+fragmentation%5C+and%5C+so%5C+on%2C%5C+R.%5C+odorata%5C+has%5C+been%5C+listed%5C+as%5C+an%5C+endangered%5C+species%5C+in%5C+%E2%80%98Chinese%5C+Plant%5C+Red%5C+Data%5C+Book%E2%80%94Rare%5C+and%5C+Endangered%5C+Plants%E2%80%99%5C+and%5C+as%5C+the%5C+third%5C-category%5C+endangered%5C+species%5C+in%5C+%E2%80%98Chinese%5C+Rare%5C+and%5C+Endangered%5C+Protective%5C+Plants%5C+List%E2%80%99.%5C+Therefore%2C%5C+it%5C+is%5C+urgent%5C+to%5C+protect%5C+this%5C+species%5C+and%5C+studying%5C+the%5C+conservation%5C+genetics%5C+of%5C+R.%5C+odorata%5C+is%5C+essentially%5C+important%5C+to%5C+work%5C+out%5C+a%5C+strategy%5C+of%5C+conservation.R.%5C+odorata%5C+comprises%5C+three%5C+double%5C-petaled%5C+varieties%5C+%5C%28R.%5C+odorata%5C+var.%5C+odorata%2C%5C+R.%5C+odorata%5C+var.%5C+erubescens%2C%5C+and%5C+R.%5C+odorata%5C+var.%5C+pseudindica%5C%29%5C+and%5C+one%5C+single%5C-petaled%5C+variety%5C+%5C%28R.%5C+odorata%5C+var.%5C+gigantea%5C%29.%5C+The%5C+taxonomy%5C+of%5C+the%5C+three%5C+double%5C-petaled%5C+varieties%5C+of%5C+R.%5C+odorata%5C+has%5C+been%5C+disputed%5C+for%5C+a%5C+long%5C+time.%5C+They%5C+have%5C+been%5C+treated%5C+as%5C+intraspecific%5C+taxa%5C+of%5C+R.%5C+odorata%5C+var.%5C+gigantea%5C+or%5C+R.%5C+chinensis%5C+by%5C+different%5C+botanist.%5C+According%5C+to%5C+the%5C+morphological%5C+analyses%2C%5C+Hurst%5C+%5C%281941%5C%29%5C+inferred%5C+that%5C+R.%5C+odorata%5C+var.%5C+odorata%5C+was%5C+the%5C+hybrid%5C+between%5C+R.%5C+odorata%5C+var.%5C+gigantea%5C+and%5C+R.%5C+chinensis.%5C+Therefore%2C%5C+in%5C+order%5C+to%5C+clarify%5C+the%5C+right%5C+protective%5C+units%2C%5C+two%5C+single%5C-copy%5C+nuclear%5C+genes%5C+%5C%28GAPDH%5C+and%5C+ncpGS%5C%29%2C%5C+together%5C+with%5C+two%5C+plastid%5C+loci%5C+%5C%28trnL%5C-F%5C+and%5C+psbA%5C-trnH%5C%29%5C+were%5C+applied%5C+to%5C+study%5C+the%5C+hybrid%5C+origin%5C+of%5C+the%5C+three%5C+double%5C-petaled%5C+varieties%5C+and%5C+to%5C+identify%5C+their%5C+possible%5C+parents.%5C+Our%5C+data%5C+suggested%5C+the%5C+hybrid%5C+origin%5C+of%5C+the%5C+three%5C+double%5C-petaled%5C+varieties.%5C+We%5C+inferred%5C+that%5C+R.%5C+odorata%5C+var.%5C+gigantea%5C+could%5C+be%5C+the%5C+maternal%5C+parent%5C+and%5C+R.%5C+chinensis%5C+cultivars%5C+be%5C+the%5C+paternal%5C+parent.%5C+It%5C+is%5C+strongly%5C+suggested%5C+that%5C+the%5C+conservation%5C+of%5C+R.%5C+odorata%5C+is%5C+the%5C+conservation%5C+of%5C+its%5C+wild%5C+type%2C%5C+R.%5C+odorata%5C+var.%5C+gigantea.%5C+We%5C+first%5C+applied%5C+seven%5C+microsatellite%5C+loci%5C+%5C%28SSR%5C%29%5C+coupled%5C+with%5C+a%5C+single%5C-copy%5C+nuclear%5C+gene%5C+GAPDH%5C+to%5C+study%5C+the%5C+genetic%5C+diversity%5C+and%5C+genetic%5C+structure%5C+of%5C+R.%5C+odorata%5C+var.%5C+gigantea.%5C+The%5C+main%5C+results%5C+are%5C+shown%5C+as%5C+follows%5C%3A1.%5C+Genetic%5C+diversity%EF%BC%9AR.%5C+odorata%5C+var.%5C+gigantea%5C+maintains%5C+high%5C+degree%5C+of%5C+genetic%5C+diversity%5C+within%5C+and%5C+among%5C+populations%5C+%5C%28SSR%5C%3A%5C+HT%5C+%3D%5C+0.738%2C%5C+HS%5C+%3D%5C+0.569%2C%5C+AR%5C+%3D%5C+5.583%2C%5C+PPB%5C+%3D%5C+97.35%25%2C%5C+I%5C+%3D%5C+1.703%5C%3B%5C+GAPDH%5C%3A%5C+HT%5C+%3D%5C+0.739%2C%5C+HS%5C+%3D%5C+0.540%5C%29.%5C+We%5C+inferred%5C+that%2C%5C+outcrossing%2C%5C+long%5C-lived%5C+tree%5C+species%2C%5C+clonal%5C+reproduction%5C+and%5C+general%5C+intraspecies%5C+hybridization%5C+between%5C+individuals%2C%5C+have%5C+contributed%5C+to%5C+the%5C+high%5C+degree%5C+of%5C+genetic%5C+diversity%5C+in%5C+R.%5C+odorata%5C+var.%5C+gigantea.2.%5C+Genetic%5C+differentiation%5C+and%5C+genetic%5C+structure%EF%BC%9AThere%5C+was%5C+some%5C+degree%5C+of%5C+genetic%5C+differentiation%5C+among%5C+populations%5C+%5C%28SSR%5C%3A%5C+GST%5C+%3D%5C+0.229%2C%5C+FST%5C+%3D%5C+0.240%5C%3B%5C+GAPDH%5C%3A%5C+GST%5C+%3D%5C+0.269%5C%29.%5C+The%5C+geographic%5C+isolation%5C+limited%5C+the%5C+dispersal%5C+of%5C+pollen%5C+or%5C+seeds%2C%5C+which%5C+resulted%5C+in%5C+the%5C+limitation%5C+of%5C+gene%5C+flow%5C+%5C%28Nm%5C+%3D%5C+0.792%5C%29.%5C+Then%2C%5C+the%5C+limited%5C+gene%5C+flow%5C+should%5C+be%5C+accounted%5C+for%5C+the%5C+genetic%5C+differentiation.%5C+Both%5C+the%5C+results%5C+of%5C+SSR%5C+data%5C+and%5C+haplotype%5C+analysis%5C+of%5C+GAPDH%5C+indicated%5C+that%2C%5C+the%5C+studied%5C+populations%5C+wer
