Journal ArticleDOI
An arabidopsis T-DNA mutant affected in Nrt2 genes is impaired in nitrate uptake.
Sophie Filleur,Marie-France Dorbe,Miguel Cerezo,Mathilde Orsel,Fabienne Granier,Alain Gojon,Françoise Daniel-Vedele +6 more
TL;DR: It is demonstrated that plant NRT2 proteins do have a role in HATS, and the de‐regulated expression of a Nicotiana plumbaginifolia Nrt2 gene restored the mutant nitrate influx to that of the wild‐type.
Journal ArticleDOI
Regulation of root ion transporters by photosynthesis: functional importance and relation with hexokinase.
Laurence Lejay,Xavier Gansel,Miguel Cerezo,Pascal Tillard,Cathrin Müller,Anne Krapp,Nicolaus von Wirén,Françoise Daniel-Vedele,Alain Gojon +8 more
TL;DR: The results indicate that the induction of AtNrt2.1 expression by sugars is unrelated to the main signaling mechanisms documented for sugar sensing in plants, such as regulation by sucrose, hexose transport, and hexokinase (HXK) sensing activity.
Journal ArticleDOI
Major Alterations of the Regulation of Root NO3− Uptake Are Associated with the Mutation of Nrt2.1 and Nrt2.2 Genes in Arabidopsis
Miguel Cerezo,Pascal Tillard,Sophie Filleur,Stéphane Muños,Françoise Daniel-Vedele,Alain Gojon +5 more
TL;DR: It is shown that the residual HATS activity in atnrt2 plants is not inducible by NO(3)(-), indicating that the mutant is more specifically impaired in the inducable component of the HATS.
