How does sulfur deficiency modulate pea response to water stress? Impact on early developing and mature seeds

2018

National audience; Pea (Pisum sativum L.) produces seeds rich in proteins but yield and quality remain unstable across years due to various stresses. Sulfur (S) deficiency and water stress are two abiotic stresses that interact in the current context of climate change and low-input practices, and recent studies suggest an important role for sulfate transport and metabolism in the plant response to water stress. To investigate the interplay between sulfur nutrition and the water stress response, sulfate-deprived pea plants were subjected to a 9-days period of water stress during the early reproductive phase. While water stress did not impact seed yield, sulfur deficiency alone or combined wi…
