【摘要】：為深入發(fā)掘小麥LBD基因的功能,利用小麥最新基因組數(shù)據(jù),通過(guò)生物信息學(xué)手段,對(duì)小麥LBD基因家族進(jìn)行了鑒定,并對(duì)其表達(dá)特性及調(diào)控網(wǎng)絡(luò)進(jìn)行了分析。鑒定結(jié)果表明,本研究得到了75個(gè)小麥LBD基因,根據(jù)系統(tǒng)進(jìn)化分析結(jié)果,可將它們劃分為ClassⅠ和ClassⅡ兩個(gè)亞家族。染色體定位結(jié)果表明,除了5D和7D外,其余染色體均含有LBD基因。共表達(dá)調(diào)控網(wǎng)絡(luò)分析表明,15個(gè)LBD基因參與了小麥功能基因調(diào)控。利用RNA-seq數(shù)據(jù)對(duì)所有小麥LBD基因在不同組織以及不同逆境脅迫下的表達(dá)情況進(jìn)行分析表明,小麥LBD基因在不同組織間和脅迫下存在著差異表達(dá),多個(gè)組織特異和脅迫響應(yīng)相關(guān)LBD基因被鑒定到,可作為后續(xù)功能研究的候選基因。
[Abstract]:In order to explore the function of wheat LBD gene, the LBD gene family of wheat was identified by bioinformatics, and its expression characteristics and regulatory network were analyzed. The results showed that 75 wheat LBD genes were obtained in this study. According to phylogenetic analysis, they can be divided into two subfamilies of Class 鈪，
