Genome-wide analysis and evolutionary study of sucrose non-fermenting 1-related protein kinase 2 (SnRK2) gene family members in Arabidopsis and Oryza
We studied the evolution based on the phylogenetic studies of SnRK2 gene family in different plant lineages. We also analyzed the chromosomal distributions of duplicated SnRK2 members in Arabidopsis and Oryza. We showed that ancestral SnRK2 gene of land plants gradually evolved by duplication and diversification. The SnRK2 gene modified itself through exonintron loss events to survive under stress conditions.
