花生AhSnRK2基因家族鉴定及生物信息学分析
Identification and Bioinformatics Analysis of AhSnRK2 Gene Family in Peanut
摘要
Abstract
Sucrose non-fermenting-1-related protein kinase 2(SnRK2)is a class of plant-specific serine/threonine(Ser/Thr)protein kinases,which play an important role in ABA signal transduc-tion,resistance to abiotic stresses,and plant development.To explore the functions of the SnRK2 gene family in peanut,a total of 22 members(named AhSnRK2.1to AhSnRK2.22)of the SnRK2 gene family were identified in peanut through bioinformatics analysis.Phylogenetic analysis showed that the 22 AhSnRK2s were divided into three different clades.The analysis of protein structure showed that AhSnRK2.1 contains a conserved S_TKc domain,an abiotic stress response domain,and an ABA-induced regulatory domain,respectively.Gene expression patterns analysis revealed that the expression level of AhSnRK2.6 in various tissues of peanut,as well as under the conditions of drought,ABA,and SA treatments,was higher than that of other AhSnRK2s.This indicates that AhSnRK2.6 may play a significant role in the stress response process of peanut.Protein-protein inter-action analysis revealed the potential roles of the AhSnRK2s family in the two pathways of phospho-rylation regulation and ABA signal response.The above results provide a basis for the functional anal-ysis of the AhSnRK2s gene family and its application in stress-resistant genetic breeding.关键词
