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 phylogenetic analysis indicated that the origin of clades 2, 3, and 4 is Gymnospermae and that these clades are closely related. The members of clade 1 included Chlorophyta to Gymnospermae. Group II, as a new branch consisting of non-seed plants, is first proposed in our research. Our results also indicated that the AAP family was already present in Chlorophyta and then expanded accompanying the development of vasculature. Concurrently, the AAP family experienced multiple duplication events that promoted the generation of new functions and differentiation of sub-functions. Conclusions: Our findings suggest that the AAP gene originated in Chlorophyta, and some non-seed AAP genes clustered in one group. A second group, which contained plants of all evolutionary stages, indicated the evolution of AAPs. These new findings can be used to guide future research.

Genome-wide study and expression analysis of Nodule-inception-like protein (NLP) gene family in Physcomitrella patens reveal its role in nitrogen response

“…Second, the presence of PpNLPs in close relationship with NLPs from vascular plants in sister-group con rms the ancestral lineage of NLPs among bryophytes and vascular plants. In a relevant study of assessing the signi cance of evolution in amino acid permeases (AAPs) gene families of 17 plants con rmed that bryophytes and vascular plants had common ancestor and gene duplications occurred in evolutionary phases (Zhang et al 2020). The evolutionary relationship can also be linked with the properties of NLPs genes and protein sequence (Yandell et al 2006).…”

The History of Lentil (Lens culinaris subsp. culinaris) Domestication and Spread as Revealed by Genotyping-by-Sequencing of Wild and Landrace Accessions

“…We identified associations with an amino acid permease, an ABC transporter, and a zinc finger BED domain-containing protein DAYSLEEPER. Such proteins have been implicated in plant meristem growth, disease resistance, nitrogen metabolism, and detoxification processes ( Knip et al, 2013 ; Do et al, 2018 ; Zhang et al, 2020 ). Further investigation on these lentil genes can offer a better view on how this crop copes with abiotic stress paving the way for novel breeds.…”

Efectos De Los Aminoácidos en La Producción De Cultivos

“…A través del floema un transportador de aminoácidos de importancia es el AAP8 (Amino Acid Permease8) o permeasa de aminoácidos (Santiago y Tegeder, 2016), que pertenece al subgrupo de AAP (Yao et al, 2020;C. Zhang et al, 2020).…”
