英文摘要: A new ribosome-in activating protein (RIP) with a molecular weight of 31 kDa induced by Cinchonaglycoside C (1) designated CIP31, was isolated from tobacco leaves. Analysis of this protein sequence indicated that it belongs to the RIP family and it was distinct from the other plant RIPs reported previously at its N-terminal amino acid sequence. CIP31 can directly impair synthesis of coat protein (CP) of tobacco mosaic virus JMV), which resulted in inhibition of TMV long distance movement and multiplication in tobacco plants at concentrations of ng/mL. Furthermore, no toxicity was shown to the growth and fertility of the plants. CIP31 was synthesized only in the presence of Cinchonaglycoside C (1) and was independent of the salicylic acid (SA) signal pathway. We provided evidence for the SA-independent biological induction of resistance.
