Ion transport and adaptation to environment in cereals
Group leader: Anne-Aliénor Véry
Senior Scientist CNRS
Key words
rice, wheat, K+, Na+, salt stress, drought, electrophysiology
Presentation
The team investigates the role of transporters and ion channels in the mineral nutrition of the plant and its adaptation to abiotic stresses: K+ deficiency, salt or water stress or soil contamination with toxic monovalent cations like 137Cs+ in relation with Fukushima accident (collaboration with Japanese teams and CEA ).
The plants studied are mainly cereals (rice , barley, wheat ), rice being selected as a model species.
Targeted transport systems mainly belong to the family of K+ and / or Na+ HKT transporters, and families of K+ carriers or channels (KUP / HAK and Shaker).
