Revisiting the functional properties of NPF6.3/NRT1.1/CHL1 in xenopus oocytes

Archive ouverte | Noguero, Mélanie | CCSD

preprint déposé dans bioRxiv. Within the Arabidopsis NPF proteins, most of the characterized nitrate transporters are low-affinity transporters, whereas the functional characterization of NPF6.3/NRT1.1 has revealed ...

AtNPF5.5, a nitrate transporter affecting nitrogen accumulation in Arabidopsis embryo

Archive ouverte | Léran, Sophie | CCSD

International audience. Dipeptide (Leu-Leu) and nitrate transport activities of 26 Arabidopsis NPF (NRT1/PTR Family) proteins were screened in Saccharomyces cerevisiae and Xenopus laevis oocytes, respectively. Dipep...

Nitrate sensing and uptake in Arabidopsis are enhanced by ABI2, a phosphatase inactivated by the stress hormone abscisic acid

Archive ouverte | Léran, Sophie | CCSD

International audience. Living organisms sense and respond to changes in nutrient availability to cope with diverse environmental conditions. Nitrate (NO3-) is the main source of nitrogen for plants and is a major c...
