Mining and evolution analysis of lateral organ boundaries domain (LBD) genes in Chinese white pear (Pyrus bretschneideri).

ABSTRACT:

Background

The lateral organ boundaries domain (LBD) gene is a plant-specific transcription factor that plays a critical role in diverse biological processes. However, the evolution and functional divergence of the LBD gene family has not yet been characterized for the Chinese White Pear.

Results

In our study, a total of 60 PbrLBDs were identified in the pear genome. The PbrLBD gene family was divided into two classes based on gene structure and phylogenetic analysis: class I (53) and class II (7). Cis-acting element analysis results suggested that PbrLBDs may participate in various biological processes, such as flavonoid biosynthetic and stress response. Synteny analysis results indicated that segmental duplication played a key role in the expansion of the PbrLBD gene famil
