MLO蛋白是具有七个跨膜结构域的高度保守蛋白。特定的MLO基因与植物疾病易感性有关。其他参与植物繁殖和根的形态发生。其余MLO的功能仍然未知。在这里，我们进行了全基因组调查的MLO家庭在8个豆科植物的不同分支的Papillionoideae亚科。共鉴定和表征了118个MLO序列。它们推导的蛋白质序列具有MLO蛋白的特征。每个豆科植物物种的MLO基因总数从13到20不等，这取决于物种。豆科植物MLO平均分布在它们的基因组中，并且倾向于定位在豆科植物基因组中保守的同线块内。系统发育分析表明，这些序列聚集在7个明确的分支。MLO蛋白质序列的比较揭示了34个进化枝特异性基序的蛋白质的可变区。豆科植物物种之间的MLO家族的比较分析也发现了一些热带豆科植物物种从菜豆分支和其他豆科植物物种之间的进化差异。总之，这项研究提供了有趣的新功能的演变MLO家庭。它还提供了有价值的线索，以确定其他MLO基因从非测序物种。
MLO proteins are highly conserved proteins with seven trans-membrane domains. Specific MLO genes have been linked to plant disease susceptibility. Others are involved in plant reproduction and in root thigmomorphogenesis. Functions of the remaining MLOs are still unknown. Here we performed a genome-wide survey of the MLO family in eight legume species from different clades of the Papillionoideae sub-family. A total of 118 MLO sequences were identified and characterized. Their deduced protein sequences shared the characteristics of MLO proteins. The total number of MLO genes per legume species varied from 13 to 20 depending on the species. Legume MLOs were evenly distributed over their genomes and tended to localize within syntenic blocks conserved across legume genomes. Phylogenetic analysis indicated that these sequences clustered in seven well-defined clades. Comparison of MLO protein sequences revealed 34 clade-specific motifs in the variable regions of the proteins. Comparative analyses of the MLO family between legume species also uncovered several evolutionary differences between the tropical legume species from the Phaseoloid clades and the other legume species. Altogether, this study provides interesting new features on the evolution of the MLO family. It also provides valuable clues to identify additional MLO genes from non-sequenced species.
