Leaf proteome analysis of eight Populus xeuramericana genotypes: genetic variation in drought response and in water-use efficiency involves photosynthesis-related proteins.

Abstract excerpt

Genetic variation of leaf proteome in drought response was investigated among eight Populus xeuramericana genotypes contrasting for their leaf carbon isotope discrimination (Delta), an estimate of intrinsic water-use efficiency. Plants were grown in open field on two similar plots. Drought was induced by an 86-day irrigation cessation on one plot, whereas a second plot remained regularly irrigated. Using 2-DE,...
