“…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).…”
