Evolutionary significance of amino acid permease transporters in 17 plants from Chlorophyta to Angiospermae

Abstract: Background: Nitrogen is an indispensable nutrient for plant growth. It is used and transported in the form of amino acids in living organisms. Transporting amino acids to various parts of plants requires relevant transport proteins, such as amino acid permeases (AAPs), which were our focus in this study. Results: We found that 5 AAP genes were present in Chlorophyte species and more AAP genes were predicted in Bryophyta and Lycophytes. Two main groups were defined and group I comprised 5 clades. Our phylogenet… Show more

“…Predicted amino acid transporter sequences (Chang et al ., 2004; Tegeder & Ward, 2012) were assembled from land plants, charophytes and chlorophytes, with representative taxa sampled as follows – angiosperms: Arabidopsis thaliana (http://www.arabidopsis.org), Amborella trichopoda (Albert et al ., 2013); gymnosperms: Picea abies (Nystedt et al ., 2013); ferns: Azolla filiculoides (Li et al ., 2018); lycophytes: Selaginella moellendorffii (Banks et al ., 2011); hornworts: Anthoceros agrestis , Anthoceros punctatus (F. W. Li et al ., 2020; C. Zhang et al ., 2020); mosses: Physcomitrium patens (Rensing et al ., 2008), liverworts: M. polymorpha (Bowman et al ., 2017); Zygnematophyceae: Mesotaenium enlicherianum , Spirogloea muscicola (Cheng et al ., 2019), Spirogyra pratensis (Cooper & Delwiche, 2016); Colecochaetaceae: Coleochaete orbicularis (Cooper & Delwiche, 2016); Klebsormidiaceae: Klebsormidium nitens (Hori et al ., 2014). Additional charophyte sequences from available transcriptomes were sometimes included (Ju et al ., 2015; Cooper & Delwiche, 2016).…”

“…While for the most part exons numbered 1-3, and in C. rubella, CbRAV4 contained 11 exons, which was obviously different from other genes (Additional le 1a). Generally, the number of exons of the same family member in any plant is relatively stable, and is not related to the length of the sequence [23]. Most proteins had two main domains: B3 and AP2, except for CbRAV4 in C. rubella, which had an extra MetAP1 domain (Additional le 1c).…”

“…Each protein had and only had both B3 and AP2 domains, except CbRAV4 which had an extra domain: MetAP1. Additionally, A complete gene sequence consists of exons and introns, and exons, as part of the coding sequence, take an crucial part in gene function [23]. The RAV members of P. abies had 1-3 exons.…”
