穗状苔藓是最基本的维管植物之一，其中一个物种，卷柏（Selaginella moellendorffii），最近被联合基因组研究所（JGI）选中进行全基因组测序。糖基转移酶（GTs）参与植物生命的许多方面，包括细胞壁生物合成、蛋白质糖基化、初级和次级代谢。在这里，我们提出了一个比较研究S。在92个GT家族和另外一个可能包括GT的家族（DUF266）中发现了moellendorffii基因组。这项研究包括苔藓小立碗藓（Physcomitrella patens），一种非维管的陆地植物，而水稻和拟南芥代表了鸭嘴草科和非鸭嘴草科的种子植物。对与细胞壁多糖生物合成特别相关的GT家族的子集的分析通过对S.莫氏细胞壁。色葡萄Moellendorffii细胞壁含有许多与种子植物细胞壁相同的组分，但在其详细结构上似乎有些不同。色葡萄与参考基因组相比，Moellendorffii基因组编码较少的GT（287个GT，包括DUF266）。在少数家系中，特别是GT51和GT78，S. moellendorffii GT没有高等植物直向同源物，但在大多数科中，S. moellendorffii GT与拟南芥和水稻具有明确的同源性。提出了一个基因命名公约的GT考虑到直系和GT家族成员。本文还讨论了S. moellendorffii进行了讨论，因为它是作为一个参考生物功能注释的GT。
Spike mosses are among the most basal vascular plants, and one species, Selaginella moellendorffii, was recently selected for full genome sequencing by the Joint Genome Institute (JGI). Glycosyltransferases (GTs) are involved in many aspects of a plant life, including cell wall biosynthesis, protein glycosylation, primary and secondary metabolism. Here, we present a comparative study of the S. moellendorffii genome across 92 GT families and an additional family (DUF266) likely to include GTs. The study encompasses the moss Physcomitrella patens, a non-vascular land plant, while rice and Arabidopsis represent commelinid and non-commelinid seed plants. Analysis of the subset of GT-families particularly relevant to cell wall polysaccharide biosynthesis was complemented by a detailed analysis of S. moellendorffii cell walls. The S. moellendorffii cell wall contains many of the same components as seed plant cell walls, but appears to differ somewhat in its detailed architecture. The S. moellendorffii genome encodes fewer GTs (287 GTs including DUF266s) than the reference genomes. In a few families, notably GT51 and GT78, S. moellendorffii GTs have no higher plant orthologs, but in most families S. moellendorffii GTs have clear orthologies with Arabidopsis and rice. A gene naming convention of GTs is proposed which takes orthologies and GT-family membership into account. The evolutionary significance of apparently modern and ancient traits in S. moellendorffii is discussed, as is its use as a reference organism for functional annotation of GTs.
