Genome-wide identification, characterization and expression analysis of populus leucine-rich repeat receptor-like protein kinase genes.

ABSTRACT:

Background

Leucine-rich repeat receptor-like kinases (LRR-RLKs) comprise the largest group within the receptor-like kinase (RLK) superfamily in plants. This gene family plays critical and diverse roles in plant growth, development and stress response. Although the LRR-RLK families in Arabidopsis and rice have been previously analyzed, no comprehensive studies have been performed on this gene family in tree species.

Results

In this work, 379 LRR-RLK genes were retrieved from the Populus trichocarpa genome and further grouped into 14 subfamilies based on their structural and sequence similarities. Approximately 82% (312 out of 379) of the PtLRR-RLK genes are located in segmental duplication blocks indicating the role of duplication process in the expansion of this gene family.
