Among them, the expression levels of Aradu.T5WNW (LRR8-containing gene, receptor-like kinase), Aradu.JM17V (LRR1- and LRR8-containing gene, disease resistance protein), and Aradu.MKP1A (LRR3-containing gene, NBS–LRR) were up-regulate at three time points, and those of Aradu.QD5DS (LRRNT_2- and LRR8-containing gene, LRR receptor) and Aradu.M0ENQ (LRRNT_2-, LRR1-, LRR6-, and LRR8-containing gene, receptor-like kinase) were up-regulated under nematode infection after 6 and 9 days. This evidence concerns the gene LRR1 and Nematoda infectious disease.
