Heightening the resistance of plants to microbial infection is a widely concerned issue, especially for economical crops. Receptor-like proteins (RLPs), typically with tandem leucine-rich repeats (LRRs) domain, play a crucial role in mediating immune activation, being an indispensable constituent in the first layer of defense. Based on an analysis of orthologs among , and using RLPs as a reference framework, we found that compared to , there were some obvious evolutionary diversities of RLPs among the three species. encoding genes were unevenly distributed on chromosomes, mainly on chrA01, chrA04, chrC03, chrC04, and chrC06. The orthologs of five RLPs (RLP3, RLP10, RLP17, RLP44, and RLP51) were highly conserved, but retrenchment and functional centralization occurred in RLPs during evolution. The RLP proteins were clustered into 13 subgroups. Ten presented expression specificity between R and S when elicited by , which might be fabulous candidates for resistance research.
增强植物对微生物感染的抗性是一个广受关注的问题,尤其是对于经济作物而言。类受体蛋白(RLP)通常具有串联富含亮氨酸重复序列(LRR)结构域,在介导免疫激活中发挥关键作用,是第一层防御中不可或缺的组成部分。基于以RLP为参考框架对[具体物种1]、[具体物种2]和[具体物种3]之间直系同源物的分析,我们发现与[具体物种1]相比,这三个[具体物种]的RLP存在一些明显的进化差异。[具体物种2]的编码基因在染色体上分布不均,主要位于chrA01、chrA04、chrC03、chrC04和chrC06上。五个RLP(RLP3、RLP10、RLP17、RLP44和RLP51)的直系同源物高度保守,但在进化过程中[具体物种2]的RLP发生了截短和功能集中化。RLP蛋白被聚类为13个亚组。当受到[具体激发因素]激发时,十个[具体物种2]在R和S之间呈现表达特异性,这可能是[具体物种2]抗性研究的绝佳候选对象。
