轮藻纲的绿色藻类（CGA或基底链藻）具有特殊的进化意义，因为它们的祖先产生了陆地植物。这些藻类的一个突出特征是它们的细胞壁与陆地植物的细胞壁具有显著的相似性。木葡聚糖（XyG）是大多数陆地植物细胞壁的主要结构组分，并且最初被认为在CGA中不存在。这项研究提供了XyG在CGA中进化的证据。这是基于a）鉴定产生XyG的遗传机制的直向同源物，B）在一系列CGA中鉴定XyG，和c）在选定的CGA中XyG的结构阐明，包括含糖醛酸的XyG。最值得注意的是，XyG岩藻糖基化，一个被认为是基本XyG结构的晚期进化阐述和相应生物合成酶的直系同源物的特征被证明存在于Mesotaenium caldariorum中。Mikkelsen等人证明了轮藻中木葡聚糖（XyG）进化的分子和细胞证据，XyG是大多数陆地植物细胞壁的结构成分。本研究描述了轮藻中XyG的结构，包括鉴定岩藻糖基化XyG，并进一步鉴定产生XyG所需的直系同源物。
The charophycean green algae (CGA or basal streptophytes) are of particular evolutionary significance because their ancestors gave rise to land plants. One outstanding feature of these algae is that their cell walls exhibit remarkable similarities to those of land plants. Xyloglucan (XyG) is a major structural component of the cell walls of most land plants and was originally thought to be absent in CGA. This study presents evidence that XyG evolved in the CGA. This is based on a) the identification of orthologs of the genetic machinery to produce XyG, b) the identification of XyG in a range of CGA and, c) the structural elucidation of XyG, including uronic acid-containing XyG, in selected CGA. Most notably, XyG fucosylation, a feature considered as a late evolutionary elaboration of the basic XyG structure and orthologs to the corresponding biosynthetic enzymes are shown to be present in Mesotaenium caldariorum. Mikkelsen et al. demonstrate molecular and cellular evidence of the evolution of xyloglucan (XyG), a structural component of the cell walls of most land plants, in charophyte algae. This study describes the structure of XyG in charophyte algae, including identification of fucosylated XyG, and furthermore identifies orthologs required to produce XyG.
