Peas, as legume crops, could play a major role in the future of food security context worldwide human nutrient deficiencies coupled with growing need to reduce consumption animal products. However, pea yields, terms quantity and quality (i.e. grain content), are both susceptible climate change, more specifically water deficits, which nowadays occur frequently during crop growth cycles tend last longer. The impact soil stress on plant development is complex, its varies depending availability (through modulation elements available soil), by plant's ability acclimate continuous or memorize previous events.To identify strategies underlying these responses events, plants were grown controlled conditions under optimal treatment different types stress; transient (during vegetative reproductive periods), recurrent, (throughout cycle). Traits related water, carbon, ionome uptake uses measured allowed identification typical cope stress.Our results highlighted (i) common three shoots, involving manganese (Mn) particular, (ii) potential implications boron (B) for root architecture modification stress, (iii) establishment an "ecophysiological imprint" system via increase nodule numbers recovery period.
