无内含子基因作为原核生物特有的特征,是研究真核生物基因结构进化的重要资源。本研究共鉴定出玉米中14623个(36.87%)无内含子基因,所占比例高于其他单子叶植物和藻类。每条染色体上的玉米无内含子基因数与染色体上的总基因数和染色体长度呈显著的线性相关。玉米中的无内含子基因在翻译和能量代谢中起着重要作用。进化分析表明,2601个无内含子基因在生命的三个区域中保守,2323个无内含子基因与其他物种的基因没有同源性。这两组无内含子基因在遗传特征、物理位置和功能上存在差异。这些结果为了解相关基因和基因组的进化模式提供了有用的来源,一些无内含子基因是进行后续功能分析的良好候选基因。
Intronless genes, as a characteristic feature of prokaryotes, are an important resource for the study of the evolution of gene architecture in eukaryotes. In the study, 14,623 (36.87%) intronless genes in maize were identified and the percentage is greater than that of other monocots and algae. The number of maize intronless genes on each chromosome has a significant linear correlation with the number of total genes on the chromosome and the length of the chromosomes. Intronless genes in maize play important roles in translation and energy metabolism. Evolutionary analysis revealed that 2601 intronless genes conserved among the three domains of life and 2323 intronless genes that had no homology with genes of other species. These two sets of intronless genes were distinct in genetic features, physical locations and function. These results provided a useful source to understand the evolutionary patterns of related genes and genomes and some intronless genes are good candidates for subsequent functional analyses specifically.
