On the roots of nitrogen uptake
WebHá 1 dia · It has been proposed that NO 3 − reduction rate in shoots controls NO 3 − uptake in roots by translocation of malate in phloem (Touraine et al., 1992). Malate in roots is decarboxylated and the produced HCO 3 − is released to solute medium to exchange with NO 3 − (Touraine et al., 1992). Hence, phloem malate transport is critical for NO ...
