Micronutrient homeostasis
Regulation and signalling of zinc deficiency adaptation response

 

Metal tolerance and accumulation
Mechanisms of adaptation to metal-rich soils in metal hyperaccumulator species

 

As an essential micronutrient zinc is of major interest in agronomy and for human and cattle nutrition. We are interested in understanding the molecular basis of plant adaptation to zinc deficiency and regulation of zinc content in plants, using the model plant species Arabidopsis thaliana.
In addition, we study plant species called hyperaccumulators, that have evolved a remarkable high level of accumulation and tolerance to zinc (as well as nickel and cadmium), and often grow in metal-rich soils. These extremophile species, Noccaea caerulescens and Alyssum pintodasilvae belong to the Brassicaceae family and are close relatives of A. thaliana.

 

A better understanding of the molecular basis of zinc homeostasis in pants (i.e., the ability to maintain an adequate zinc supply at cellular level) and the mechanisms involved in adaptation to zinc deficiency or to excess zinc in soil, will contribute to the development of plant-based solutions addressing nutrient use efficiency and adaptation to nutrient-limited or toxic soils.
