| 초록 | Korean ginseng (Panax ginseng) has long been cultivated as an important economic medicinal plant for a long time. Due to the perennial growth patterns and the long-term agricultural cultivation methods of Korean ginseng, they are always vulnerable to various environmental stress conditions. ABSCISIC ACID (ABA) is an essential plant hormone associated with seed development and diverse abiotic stress responses including drought, cold and salinity stress. Plants also regulate their immune responses and growth patterns by modulating ABA responses to extend their ability of stress tolerance. With recent advances in genome sequencing technology, we here firstly reported the functional features of genes related to canonical ABA signaling pathway in P. ginseng genome. Based on the protein sequences and functional genomic analysis of Arabidopsis thaliana, we successfully identified the ABA related genes. Our functional genomic characterizations clearly showed that the ABA signaling related genes consisting with the ABA receptor proteins (PgPYLs), kinase family (PgSnRKs) and transcription factors (PgABFs, PgABI3s and PgABI5s) are evolutionary conserved in the P. ginseng genome. We confirmed that overexpressing ABA related genes of P. ginseng were completely restored the ABA responses and stress tolerance in ABA defective Arabidopsis mutants. Finally, tissue and age specific spatio-temporal expression patterns of the identified ABA-related genes in P. ginseng tissues were also characterized by using various available RNA sequencing data. The present study provided ABA signal transduction related genes and their functional genomic information related to the growth and development of Korean ginseng. In addition, the results of this study would be useful for the breeding or artificial selection of ginseng which is resistant to various stresses. | ||
