Interplay between sulfur nutrition and water stress tolerance in pea : a focus on seed development and composition
2019
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…

Time-series RNA-seq analysis of pea seeds during development under control and drought conditions
2019
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…
Transcriptomic and metabolomic responses of the nodulated pea root system during rewatering
2019
National audience; In pea (Pisum sativum), as in other legumes, nitrogen nutrition relies on two different sources: soil mineral nitrogen supply via roots and and symbiotic atmospheric N2 fixation within root nodules. However symbiotic nitrogen fixation is very sensitive to abiotic stresses, especially drought, which is becoming increasingly frequent in the current context of climate change. Although the ability of a crop to recover after a drought period can determine both its survival and its yield at harvest, little is known about the physiological and molecular mechanisms occurring during recovery. In this work, we aimed at characterizing the kinetics of growth and nitrogen acquisition …

Vulnerability of the nucleus accumbens neuronal network to developmental n-3 PUFA deficiency: consequences on the reward and motivation system
2019
National audience; Various, though distinct psychiatric disorders, such as Schizophrenia, bipolar disorder or major depression are associated with a dysfunction of the reward system linked to an alteration of dopamine transmission. Furthermore, these pathologies are also accompanied by changes in lipid metabolism and in particular a decrease in the brain content n-3 polyunsaturated fatty acid (PUFA) in the nervous system. However, the implication of brain lipid composition in the etiology of psychiatric endophenotypes has been overlooked. The aim of this study was to investigate a potential causal link between n-3 PUFA deficiency and deficits in reward processing. Using operant conditioning…

How Geography and Climate Shaped the Genomic Diversity of Italian Local Cattle and Sheep Breeds
2022
International audience; Understanding the relationships among geography, climate, and genetics is increasingly important for animal farming and breeding. In this study, we examine these inter-relationships in the context of local cattle and sheep breeds distributed along the Italian territory. To this aim, we used redundancy analysis on genomic data from previous projects combined with geographical coordinates and corresponding climatic data. The effect of geographic factors (latitude and longitude) was more important in sheep (26.4%) than that in cattle (13.8%). Once geography had been partialled out of analysis, 10.1% of cattle genomic diversity and 13.3% of that of sheep could be ascribe…
