Phylogenetic analyses and in-seedling expression of ammonium and nitrate transporters in wheat.

ABSTRACT: Plants deploy several ammonium transporter (AMT) and nitrate transporter (NRT) genes to acquire NH₄⁺ and NO₃^- from the soil into the roots and then transport them to other plant organs. Coding sequences of wheat genes obtained from ENSEMBL were aligned to known AMT and NRT sequences of Arabidopsis, barley, maize, rice, and wheat to retrieve homologous genes. Bayesian phylogenetic relationships among these genes showed distinct classification of sequences with significant homology to NRT1, NRT2, and NRT3 (NAR2). Inter-species gene duplication analysis showed that eight AMT and 77 NRT genes were orthologous to the AMT and NRT genes of aforementioned plant species. Expression patterns of these genes were studied via whole transcriptome sequencing of
