Legume adaptation to sulfur deficiency

BAPSPEEAGEAPSIIPM; Because sulfur-deficiency represents an agronomic issue for crops and notably for the quality of legume products, it is necessary to provide sulfur fertilizers according to crop sulfur needs along with improving sulfur use efficiency. To achieve this goal, increased knowledge of how plants respond to sulfur-deficiency is required. We subjected Medicago truncatula, a model legume species, to sulfur deficiency at different developmental stages and compared yield, nutrient allocation and seed traits. We revealed an impressive plasticity of M. truncatula that varied according to the S-stress period and influenced seed composition and germination. Sulfur deficiency at a mid-ve…
