Abstract

Abstract: In this study，45 LBD genes were identified and widely distributed on 9 chromosomes of pepper genome. The structures of these genes were relatively simple for whose intron numbers were less than 3. According to the phylogeny relationship，pepper LBD genes could be classified into 2 classes（ClassⅠand ClassⅡ）including 7 subfamilies（Ⅰa，Ⅰb，Ⅰc，Ⅰd，Ⅰe，Ⅰa andⅠb）. The expression patterns of pepper LBD genes in different tissues and development stages showed spatial and temporal expression differences. The qRT-PCR revealed that part of LBD genes could be activated or repressed by heat shock，and the ClassⅡ genes were more sensitive to heat stress than ClassⅠ.

Key words: pepper, LBD gene family, phylogeny analysis, gene expression
