Replanting alters nitrogen uptake and the expression level of ammonium transporter genes in grapevine.

ABSTRACT: Replanting disease caused stunted grapevines growth, hindering the healthy and sustainable development of the grape industry. Nitrogen metabolism is closely related to plant growth, however the effect of replanting on nitrogen metabolism in grape have seldom been reported. In this study, we used 'Beta' grape (Vitis riparia × V. labrusca cv.) cuttings as experimental materials to investigate the nitrogen content, nitrogen uptake behavior, and ammonium transporter genes (AMT) expression levels in grapevines after replanting. The results indicated the total nitrogen content in both the roots and leaves of the replanted grapevines decreased. After replanting, the net influx rate of NO₃^- into grapevine roots decreased, whereas that of NH₄⁺ increased.
