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


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).

Press release: “coping with soil salinity: Lessons from a wild rice species”

Climate change and sea level rise is increasingly affecting coastal regions of India. Intrusion of sea water into agricultural lands in coastal regions is increasing soil salinity (increasing soil sodium ion content), affecting agricultural productivity.
