摘 要：Plants mainly uptake inorganic nitrogen from soil as ammonium and *** energy is required to assimilate ammonium compared to nitrates,and plants prefer to take up ammonium when the external nitrogen concentration is *** the patterns and mechanisms of ammonium absorption can help improve crop nitrogen *** this study,we isolated MdSAT1,a gene of apple encoding an ammoniumresponsive bHLH transcription ***1 promoted the growth and development of lateral roots and root *** of MdSAT1 increased the transcript levels of genes related to ammonium uptake,indicating that MdSAT1 can regulate ammonium uptake and utilization at the transcriptional ***1 also can modulate reactive oxygen species(ROS)accumulation to ultimately regulate plant *** together,these findings provide insight for us to further study the mechanisms by which MdSAT1 controls ammonium utilization as well as plant growth and development.
