evolution | sequence structure and length of the TaNAAT1, TaNAAT2 and TaDMAS1 genes in Triticum aestivum cv. Gladius, comparison, phylogenetic tree, overview | Triticum aestivum |
metabolism | iron (Fe) uptake in graminaceous plant species occurs via the release and uptake of Fe-chelating compounds known as mugineic acid family phytosiderophores (MAs). In the MAs biosynthetic pathway, nicotianamine aminotransferase (NAAT) and deoxymugineic acid synthase (DMAS, EC 1.1.1.285) enzymes catalyse the formation of 2'-deoxymugineic acid (DMA) from nicotianamine (NA). The TaNAAT1, TaNAAT2 and TaDMAS1 genes are differentially regulated by plant Fe status and their expression is significantly upregulated in root tissues from day five onwards during a seven-day Fe deficiency treatment. Expression levels of the TaNAAT1, TaNAAT2, and TaDMAS1 genes are temporally regulated in wheat roots to enable rapid DMA biosynthesis in response to Fe deficiency and avoid NA depletion | Triticum aestivum |
physiological function | the nicotianamine aminotransferase and deoxymugineic acid synthase genes are essential to iron uptake in Triticum aestivum | Triticum aestivum |
