MdMYB10 affects nitrogen uptake and reallocation by regulating the nitrate transporter MdNRT2.4-1 in red-fleshed apple
文献摘要：
Nitrate is the major nitrogen source for higher plants.In addition to serving as a nutrient,it is also a signaling molecule that regulates plant growth and development.Although membrane-bound nitrate transporter/peptide transporters(NRT/PTRs)have been extensively studied and shown to regulate nitrate uptake and movement,little is known about how these factors are regulated by the external nitrogen environment.Red-fleshed apple,whose coloration is determined by the transcription factor MdMYB10,had higher nitrate uptake efficiency than non-red-fleshed apple.Nitrate assimilation and utilization were higher in red-fleshed apple cultivars,and comparative transcriptome analysis showed that the expression of genes encoding the NRT2s was increased in red-fleshed apple.In vitro and in vivo experiments showed that MdMYB10 directly bound to the MdNRT2.4-1 promoter to transcriptionally activate its expression,resulting in enhanced nitrate uptake.MdMYB10 also controlled nitrate reallocation from old leaves to new leaves through MdNRT2.4-1.Overall,our findings provide novel insights into the mechanism by which MdMYB10 controls nitrate uptake and reallocation in apple,which facilitates adaptation to a low-nitrogen environment.
