Abstract As the preferred nitrogen (N) source, ammonium (NH4+
) contributes to
plant growth and development and fruit quality. In plants, NH4+ uptake is facilitated by a family of NH4+ transporters (AMT). However, the molecular mechanisms and functional characteristics of the AMT genes in peach have not been
mentioned yet. In this present study, excess NH4+ stress severely hindered shoot
growth and root elongation, accompanied with reduced mineral accumulation,
decreased leaf chlorophyll concentration, and stunned photosynthetic performance. In addition, we identified 14 putative AMT genes in peach (PpeAMT).
Expression analysis showed that PpeAMT genes were differently expressed in
peach… More >
