摘要
The plant hormone salicylic acid （SA） plays a prominent role in modulating plant immune responses against diverse pathogens. SA also influences other physiological pro- cesses in plants, such as senescence-associated gene expres- sion, basal thermogenesis, and seed germination （Vlot et al., 2009）. Because of the critical role of SA in regulating plant immunity, growth, and development, there has been immense research about SA, which has resulted in the dis- covery of numerous plant genes involved in SA biosynthesis or signal transduction. One of the most notable findings was the identification of NPR1 （non-expressor of pathogen- esis protein 1） （Cao et al., 1994; Delaney et al., 1995）, a gene that encodes a master regulatory protein of SA-dependent defense responses and is a transcriptional co-activator of the TGA clade of bZIP transcription factors （transcription factors that contain basic region/leucine zipper motif）.
