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

We identified the number and type of LRR-containing genes in A. duranensis. The LRR-containing genes that were found appear to be involved in responses to nematode infection. The number of LRR8 domains was negatively correlated with expression after nematode infection. The WRKY transcription factor may regulate resistance to nematode infection based on LRR-containing genes. Our results could improve the understanding of resistance to nematodes and molecular breeding in peanuts.
