Genome-wide identification and evolutionary analysis of nucleotide-binding site-encoding resistance genes in Lotus japonicus (Fabaceae)

H. Song, Wang, P. F., Li, T. T., Xia, H., Zhao, S. Z., Hou, L., and Zhao, C. Z., Genome-wide identification and evolutionary analysis of nucleotide-binding site-encoding resistance genes in Lotus japonicus (Fabaceae), vol. 14, pp. 16024-16040, 2015.

Nucleotide-binding site (NBS) disease resistance genes play a crucial role in plant defense responses against pathogens and insect pests. Many NBS-encoding genes have been detected in Lotus japonicus, an important forage crop in many parts of the world. However, most NBS genes identified so far in L. japonicus were only partial sequences. We identified 45 full-length NBS-encoding genes in the L. japonicus genome, and analyzed gene duplications, motifs, and the molecular phylogeny to further understand the NBS gene family.
