MADS-box 基因家族在蒺藜苜蓿的全基因组分析
Genome-wide identification and investigation of the MADS-box gene family in Medicago truncatula
摘要
Abstract
MADS-box genes encode important transcription factors in plants that are involved in many processes during growth,development and reproduction.A Pfam domain search of the Medicago truncatula genome re-vealed 138 putative MADS-box genes.These genes were classified into two classes,type I (92 members)and type II (46 members),based on multiple alignment and phylogenetic analysis.There were 134 MADS-box genes present on all chromosomes in M.truncatula,while four were located on the super-contigs.Like Arabi-dopsis and rice MADS-box genes,those MADS-box genes expanded through gene duplication events in M. truncatula ,especially the type I genes.There were many duplicate gene clusters,where MADS-box genes with high degrees of similarity were clustered across the M.truncatula genome.Analysis of RNA-seq data from dif-ferent tissues in M.truncatula revealed that MADS-box genes are expressed in seedpod,flower and other tis-sues.This expression pattern suggests that the MADS-box genes play an important role in tissue differentia-tion,development and reproduction process in M.truncatula.关键词
