Genome-Wide Identification and Expression Analysis of AMT Gene Family in Apple (Malus domestica Borkh.)

Ammonium is one of the prevalent nitrogen sources for growth and development higher plants. acquisition from soil facilitated by ammonium transporters (AMTs), which are plasma membrane proteins that exclusively transport ammonium/ammonia. However, functional characteristics molecular mechanisms AMTs in apple remain unclear. In this work, 15 putative AMT genes were identified classified into four clusters (AMT1–AMT4) apple. According to expression analysis, these had varying expressions roots, leaves, stems, flowers fruits. Some them strongly affected diurnal cycles. showed multiple transcript patterns N regimes quite responsive osmotic stress. addition, phosphorylation analysis revealed there some conserved residues within C-terminal proteins. Furthermore, detailed research was conducted on AMT1;2 functioning heterologous yeast. The present study expected provide basic bioinformatic information profiles family lay a basis exploring roles regulation
