Frequent Gene Duplication/Loss Shapes Distinct Evolutionary Patterns of NLR Genes in Arecaceae Species
Nucleotide-binding leucine-rich repeat (NLR) genes play a key role in plant immune responses and have co-evolved with pathogens since the origin of green plants. Comparative genomic studies on the evolution of NLR genes have been carried out in several angiosperm lineages. However, most of these lin...

| description | Nucleotide-binding leucine-rich repeat (NLR) genes play a key role in plant immune responses and have co-evolved with pathogens since the origin of green plants. Comparative genomic studies on the evolution of NLR genes have been carried out in several angiosperm lineages. However, most of these lineages come from the dicot clade. In this study, comparative analysis was performed on NLR genes from five Arecaceae species to trace the dynamic evolutionary pattern of the gene family during species speciation in this monocot lineage. The results showed that NLR genes from the genomes of <i>Elaeis guineensis</i> (262), <i>Phoenix dactylifera</i> (85), <i>Daemonorops jenkinsiana</i> (536), <i>Cocos nucifera</i> (135) and <i>Calamus simplicifolius</i> (399) are highly variable. Frequent domain loss and alien domain integration have occurred to shape the NLR protein structures. Phylogenetic analysis revealed that NLR genes from the five genomes were derived from dozens of ancestral genes. <i>D. jenkinsiana</i> and <i>E. guineensis</i> genomes have experienced “consistent expansion” of the ancestral NLR lineages, whereas a pattern of “first expansion and then contraction” of NLR genes was observed for <i>P. dactylifera</i>, <i>C. nucifera</i> and <i>C. simplicifolius</i>. The results suggest that rapid and dynamic gene content and structure variation have shaped the NLR profiles of Arecaceae species. |
