全基因组水平紫花苜蓿WRKY转录因子家族鉴定与表达模式分析
Identification and expression pattern of the WRKY transcription factor family in Medicago sativa
摘要
Abstract
WRKY transcription factors are one of the largest gene families in plants and play important roles in plant growth and development as well as in abiotic stress processes.Currently,members of the WRKY gene family have been extensively studied and analyzed in a variety of plant species.However,the alfalfa(Medicago sativa)WRKY transcription factors have not been identified and analyzed at the genome-wide level.In this study,we systematically identified alfalfa WRKY gene family members and analyzed their expression patterns under different stress treatments.We showed that a total of 198 WRKY transcription factors were unevenly distributed across 32 chromosomes in alfalfa,with chromosome 7 having the largest number.The phylogenetic tree results show that the WRKY gene family members can be divided into three groups.Among these WRKY transcription factors,42 responded to salt stress,7 to alkali stress,19 to cold stress and 37 to drought stress,and MsWRKY154 and MsWRKY166 were found to respond to both salt,drought,and cold as well as alkali stress.The results of this study provide a foundation for the intensive investigation of the biological function of WRKY transcription factors in alfalfa,and can also provide valuable information for molecular breeding in alfalfa.关键词
