Genome-wide identification of LRR-containing sequences and the response of these sequences to nematode infection in Arachis duranensis.

ABSTRACT:

Background

Leucine-rich repeat (LRR)-containing genes are involved in responses to various diseases. Recently, RNA-seq data from A. duranensis after nematode (Meloidogyne arenaria) infection were released. However, the number of LRR-containing genes present in A. duranensis and the response of LRR-containing genes to nematode infection are poorly understood.

Results

In this study, we found 509 amino acid sequences containing nine types of LRR domains in A. duranensis. The inferred phylogenetic relationships revealed that the nine types of LRR domains had two originations. The inferred selective pressure was mainly consistent with LRR domains undergoing purifying selection. Twenty-one LRR-containing genes were associated with possible resistance to nematode infection after 3,
