摘要
Homologs of Tobacco mosaic 病毒 30K cell-to-cell movement 蛋白質 are encoded by diverse plant 病毒es. Mechanisms of action and 演化ary origins of these 蛋白質s remain obscure. We expand the picture of conservation and 演化 of the 30K 蛋白質s, producing sequence alignment of the 30K superfamily with the broadest 系統發育 coverage thus far and illuminating structural features of the core all-beta fold of these 蛋白質s. integrated copies of pararetro病毒 30K movement genes are prevalent in euphyllophytes, with at least one copy intact in nearly every examined 物種, and mRNAs detected for most of them. Sequence analysis suggests repeated integrations, pseudogenizations, and positive selection in those pro病毒 genes. An unannotated 30K-superfamily gene in Arabidopsis thaliana 基因組 is likely expressed as a fusion with the At1
