AbstractSucrose non-fermenting1-related protein kinases (SnRKs) are a type of Ser/Thr protein kinases, and they play an important role in plant life, especially in metabolism and responses to environmental stresses. However, there is limited information on SnRK genes in Dendrobium officinale. In the present research, a total of 36 DoSnRK genes were identified based on genomic data. These DoSnRKs could be grouped into three subfamilies, including 1 member of DoSnRK1, 7 of DoSnRK2, and 28 of DoSnRK3. The gene structure analysis of DoSnRK genes showed that 17 members had no introns, while 16 members contained six or more introns. The conserved domains and motifs were found in the same subfamily. The various cis-elements present in the promoter regions showed that DoSnRK genes could respond to stresses and hormones. Furthermore, the expression patterns of DoSnRK genes in eight tissues were investigated according to RNA sequencing data, indicating that multiple DoSnRK genes were ubiquitously expressed in these tissues. The transcript levels of DoSnRK genes after drought, MeJA, and ABA treatments were analyzed by quantitative real-time PCR and showed that most DoSnRK genes could respond to these stresses. Therefore, genomic characterization and expression analyses provide valuable information on DoSnRK genes for further understanding the functions of SnRKs in plants.
