Time-series RNA-seq analysis of pea seeds during development under control and drought conditions

National audience; Pea (Pisum sativum) produces seeds rich in proteins. However, protein content and seed quality can be impacted by environmental factors including drought. Accumulation of seed storage proteins (SSP) during seed filling is a highly regulated process. While proteomics of SSP deposition in pea seeds is well documented, knowledge of the underlying regulatory gene networks, either in control or stress conditions, is lacking. In this study, a RNA-seq based transcriptome analysis of seed development in control and water stress condition was carried out. Developing seeds were collected at six time points, from late embryogenesis to early maturation. RNA-seq was performed on an Il…

Studying the interplay between sulfur nutrition and water stress tolerance in pea by proteomics : a focus on seed development and composition

International audience; Water stress and sulfur-deficiency are two constraints increasingly faced by crops due to climatechange and low-input practices. To investigate their interplay in the grain legume pea (Pisum sativumL.), sulfate was depleted at mid-vegetative stage and a moderate 9-day water stress period was imposedduring the early reproductive phase. The combined stress accelerated seed production, lowering yield,one-seed weight and seed number per plant, but rebalanced seed protein composition. In fact, themoderate water stress mitigated the negative effect of sulfur-deficiency on the accumulation of sulfurrichproteins in seeds, probably due to a lower seed sink strength for nitrog…

Interplay between sulfur nutrition and water stress tolerance in pea : a focus on seed development and composition

International audience; Water stress and sulfur-deficiency are two constraints increasingly faced by crops due to climate change and low-input practices. To investigate their interplay in the grain legume pea (Pisum sativum L.), sulfate was depleted at mid-vegetative stage and a moderate 9-day water stress period was imposed during the early reproductive phase. The combined stress accelerated seed production, lowering yield, one-seed weight and seed number per plant, but rebalanced seed globulin composition. In fact, the moderate water stress mitigated the negative effect of sulfur-deficiency on the accumulation of sulfur-rich globulins in seeds, probably due to a lower seed sink strength f…
