Two water-uptake strategies were found in stem-prolongation stage of rapeseeds. Tolerant genotypes are included in both groups – water-savers and water-spenders. In the water-savers group, accumulation of fewer proteins was changed in contrast to water-spenders. Savers show higher: nitrogen metabolism, ATP conversion proteins, ROS, signalling, and stress-related proteins. Spenders down-accumulate proteins in carbohydrate/energy metabolism and photosynthesis.
