基于全基因组水平的花生FAR1转录因子家族分析OA北大核心CSTPCD
Genome-Wide Analysis of the FAR1 Gene Family in Peanut
FAR1 是一类起源于转座子酶的转录因子,在光敏色素 A(phyA)信号通路的启动中起到非常重要的作用.基于全基因组水平对其家族分析,可为深入研究 FAR1 基因在花生生长发育、逆境胁迫响应中的分子调控机理提供依据.本研究在花生基因组中共鉴定出 60 个FAR1 基因,该转录因子家族成员分成 3 个亚组,Ⅰ、Ⅱ、Ⅲ亚组中分别包含了 21、20 和 19 个花生FAR1 蛋白.65% 直系同源基因的Ka/Ks值小于 0.5,这些基因结构稳定、较为保守,经历了较强的负选择作用.转录组数据分析发现,大部分FAR1 基因在花生叶片中表达.本研究结果有助于了解花生 FAR1 基因家族的进化与功能,为下一步深入研究该基因家族的功能提供依据.
FAR1,a class of transcription factors derived from mutator-like transposases,plays an impor-tant role in the phytochrome A signaling pathway.Genome-wide analysis of FAR1 is helpful to understand the molecular mechanism of the FAR1 family in development and in response to abiotic stress pathways in peanut.60 FAR1 genes were identified in peanut.The genes were divided into three groups by phylogenetic analysis.21,20 and 19 proteins were classed intoⅠ,ⅡandⅢgroups.The Ka/Ks ratio of 65% orthologs was less than 0.5,which indicated that these genes were structurally stable and conserved,and experienced strong negative selection.Using online published transcriptome data,it was found that the majority of FAR1 genes were mostly expressed in the leaf.The results provide a foundation for future studies of the functions and regulatory mechanisms of FAR1 family members.
