大多数后生动物使用己糖转运体从饮食中获取己糖，并作为在体内分配碳和能量的运输形式；昆虫使用海藻糖，植物使用蔗糖作为它们转运的主要形式。植物基因组包含至少三个单糖和双糖转运蛋白家族：与酵母和人类葡萄糖转运蛋白进化密切相关的单糖/多元醇转运蛋白家族；与己糖转运蛋白相似的SUT转运蛋白家族，属于主要的促进剂超家族，但与己糖转运蛋白只有极少的氨基酸序列同源性；以及动植物之间保守的SWEET转运蛋白家族。最近，已经确定了卷柏属植物的基因组序列。为了研究植物糖转运的进化，我们仔细地注释了卷柏属糖转运体的补体。我们回顾了目前关于糖转运的知识，并提供了Selaginella（和physcomitella）中MST和SUT同源物的系统发育分析。
Most metazoa use hexose transporters to acquire hexoses from their diet and as a transport form for distributing carbon and energy within their bodies; insects use trehalose, and plants use sucrose as their major form for translocation. Plant genomes contain at least three families of mono- and disaccharide transporters: monosaccharide/polyol transporters that are evolutionary closely related to the yeast and human glucose transporters, sucrose transporters of the SUT family, which similar to the hexose transporters belong to the major facilitator superfamily, but share only minimal amino acid sequence homology with the hexose transporters, and the family of SWEET sugar transporters conserved between animals and plants. Recently, the genome sequence of the spikemoss Selaginella has been determined. In order to study the evolution of sugar transport in plants, we carefully annotated of the complement of sugar transporters in Selaginella. We review the current knowledge regarding sugar transport in spikemoss and provide phylogenetic analyses of the complement of MST and SUT homologs in Selaginella (and Physcomitrella).
