Amino acids play fundamental roles in a multitude of functions including protein synthesis, hormone metabolism, nerve transmission, cell growth, production of metabolic energy, nucleobase synthesis, nitrogen metabolism, and urea biosynthesis. Selaginella as a member of the lycophytes is part of an ancient lineage of vascular plants that had arisen ∼400 million years ago. In angiosperms, which have attracted most of the attention for nutrient transport so far, we have been able to identify many of the key transporters for nitrogen. Their role is not always fully clear, thus an analysis of Selaginella as a representative of an ancient vascular plant may help shed light on the evolution and function of these diverse transporters. Here we annotated and analyzed the genes encoding putative transporters involved in cellular uptake of amino acids present in the Selaginella genome.
氨基酸在多种功能中发挥着基本作用，包括蛋白质合成、激素代谢、神经传递、细胞生长、代谢能量产生、核苷合成、氮代谢和尿素生物合成。卷柏作为石松类植物的一员，是起源于约 4 亿年前的维管植物古老谱系的一部分。在被子植物中，迄今为止，我们已经能够鉴定出许多用于氮素运输的关键转运蛋白，它们的作用并不总是完全清楚，因此分析卷柏作为一种古老的维管植物代表可能有助于阐明这些不同转运蛋白的进化和功能。在这里，我们注释和分析了参与细胞摄取卷柏基因组中存在的氨基酸的假定转运蛋白的基因。
