Multi-cation exchanges involved in cesium and potassium sorption mechanisms on vermiculite and micaceous structures
Vermiculite and micaceous minerals are relevant Cs+ sorbents in soils and sediments. To understand the bioavailability of Cs+ in soils resulting from multi-cation exchanges, sorption of Cs+ onto clay minerals was...

Root-derived GA12 contributes to temperature-induced shoot growth in Arabidopsis
Plants are able to sense a rise in temperature of several degrees, and appropriately adapt their metabolic and growth processes. To this end, plants produce various signalling molecules that act throughout the...

Ectosymbiotic bacteria at the origin of magnetoreception in a marine protist
Mutualistic symbioses are often a source of evolutionary innovation and drivers of biological diversification1. Widely distributed in the microbial world, particularly in anoxic settings2,3, they often rely on me...

Cesium Translocation in Rice
To breed a low Cs rice variety, it is important to clarify the mechanism of Cs transport in a plant. In the present report, we found a difference in Cs distribution in rice cultivars using a 137Cs tracer experime...

Zn/Cd/Co/Pb P1b-ATPases in Plants, Physiological Roles and Biological Interest
P1B-ATPases are cation transporters found in all organisms. In plants, they are found in almost all membranes including plasma membrane, internal chloroplastic membrane, thylakoids, post-Golgi and tonoplast, wher...

Open AccessAtMRP6/AtABCC6, an ATP-Binding Cassette transporter gene expressed during early steps of seedling development and up-regulated by cadmium in Arabidopsis thaliana
ABC proteins constitute one of the largest families of transporters found in all living organisms. In Arabidopsis thaliana, 120 genes encoding ABC transporters have been identified. Here, the characterization of ...

Open AccessIsolation of a strong Arabidopsis guard cell promoter and its potential as a research tool
A common limitation in guard cell signaling research is that it is difficult to obtain consistent high expression of transgenes of interest in Arabidopsis guard cells using known guard cell promoters or the const...

Pharmacological properties of slow anion currents in intact guard cells of Arabidopsis. Application of the discontinuous single-electrode voltage-clamp to different species
More electrophysiological studies have been carried out on guard cells than on any other cell type of vascular plants. The characterization of their ion channels has been achieved using mainly the whole-cell p...
