Protéomique Shotgun des graines de féveroles : vers l’identification de protéines associées à la résistance aux bruches

2021

Le protéome des graines en développement de lignées recombinantes issues du croisement entre desgénotypes de féverole résistants et sensibles aux bruches a été étudié par l’approche shotgun. Cetravail a permis d’identifier 749 protéines au début du remplissage des graines, dont 80 sontdifférentiellement accumulées entre les lignées sensibles et résistantes aux bruches. En plus de fournirun premier aperçu des protéines présentes à ce stade clé du développement des graines chez laféverole, ces données ont fait émerger des protéines candidates pour améliorer la résistance desgraines aux bruches. Parmi les protéines préférentiellement accumulée dans les lignées résistantes estune glycoprotéine …

A holistic overview of the impact of sulfur deficiency in pea facing water deficit

2022

We report on the interplay between water deficit and sulfur deficiency, two constraints that are increasingly faced by crops due to climate change and low-input agricultural practices. In particular, we aim at better understanding the role of sulfur nutrition in the trade-off between seed quality establishment and plant stress tolerance in pea (Pisum sativum L.), a grain legume crop which has a pivotal role to play in both agroecological and food transitions. Like other legumes, pea is able to accumulate large amounts of seed proteins even in the absence of nitrogen fertilizers thanks to its symbiosis with N2-fixing soil bacteria. In this study, we deprived pea plants (cv. Caméor) of sulfur…

Impact of Bacterial Siderophores on Iron Status and Ionome in Pea

2020

National audience; Including more grain legumes in cropping systems is important for the development of agroecological practices and the diversification of protein sources for human and animal consumption. Grain legume yield and quality is impacted by abiotic stresses resulting from fluctuating availabilities in essential nutrients such as iron deficiency chlorosis (IDC). Promoting plant iron nutrition could mitigate IDC that currently impedes legume cultivation in calcareous soils, and increase the iron content of legume seeds and its bioavailability. There is growing evidence that plant microbiota contribute to plant iron nutrition and might account for variations in the sensitivity of pe…

Dissection of pea responses to water stress during seed filling identifies candidate genes for drought tolerance

2018

International audience; Given their ability to fix atmospheric nitrogen, legumes are pivotal to the development of sustainable agriculture in Europe as a source of protein for food and feed. Pea (Pisum sativum) is currently the leading grain legume crop in France and major efforts are being made to reintroduce legumes as protein crops in Europe. However, instability of seed yield and quality due to environmental fluctuations still represent a real barrier for the development of these cultures, and breeding for stable yields is needed. In pea, drought stress occurring during the reproductive phase can greatly affect seed yield and quality. We investigated the response of pea plants (var. Cam…

Role of vacuolar sulfate in nutritional quality of pea seeds

2022

Grain legumes have a key role to play in both agroecological and food transitions. Indeed, these plants are able to accumulate large amounts of proteins in their seeds even in the absence of nitrogen fertilization thanks to symbiotic N2 fixation in the root nodules. However, legumes are exposed to abiotic stresses, including nutrient deficiencies, making it important to optimize nutrient use efficiency for maintaining seed protein content and quality. Seed protein quality refers to the ability of the seed proteins to meet the body’s requirements for essential amino acids. It strongly depends on the amino acid balance, which determines protein digestibility. In pea (Pisum sativum) seeds, met…

Use of translational genomics to identify genes important for legume seed development

2015

BAP Pôle GEAPSI; International audience; We have exploited the extensive synteny between the model legume Medicago truncatula and the cultivated garden pea, Pisumsativum, to identify loci controlling seed filling and seedcomposition in the crop species. QTLs for these traits are mapped by analyzing variation with in collections of recombinant inbred lines. Candidate genes with in the QTL intervals are identified by reference to the M.truncatula genomic sequence. This approach was used to uncover an endosperm subtilase that is associated with syntenic seed weight QTLs in Medicago and pea, and we discuss the possible role played by this enzyme in contributing to final seed weight.

Multi-omics network analysis identifies putative regulators of molecular responses to water stress and sulfur deficiency in Pisum sativum

2022

Plants in their physical environment face multiple biotic and abiotic stresses duringtheir life cycle. In nature, environmental stresses often co-occur – such as water deficit andnutrient deficiencies – and can have synergistic, antagonistic or additive effects on the plantmolecular responses. In pea (Pisum sativum), combination of water stress (WS) and sulfur (S)deficiency showed a mitigation effect on the seed protein composition, as compared to Sdeficiency occurring alone (Henriet et al., 2019). To better understand how pea responds toWS and/or S deficiency, a multi-omics (transcriptomics, proteomics, metabolomics, ionomics)analysis has been performed from leaf samples collected during a…

Germination and storage protein mobilisation of Trifolium subterraneum Var 45C seeds under hypoxic treatment

2007

International audience; The rate, speed and latency period of germination were defined for seeds of Trifolium subterraneum variety 45 C. The latency period was 12 hours on distilled water. The hypoxic stress was applied at the beginning (T12) and the end of latency period (T24). It consists on the addition of nitrogen (N2) under 1 bar pressure in hermetically closed boxes during 2 hours. The germination of treated seeds was then assessed on distilled water. The germination test during hypoxic treatment showed that the hypoxic stress delayed germination, slowing down its speed and decreasing the final percentage of germinated seeds. In order to better understand this depressive effect observ…

International audience; Drought and salinity are two frequently combined abiotic stresses that affect plant growth, development, and crop productivity. Sulfate, and molecules derived from this anion such as glutathione, play important roles in the intrinsic responses of plants to such abiotic stresses. Therefore, understanding how plants facing environmental constraints re-equilibrate the flux of sulfate between and within different tissues might uncover perspectives for improving tolerance against abiotic stresses.

Transcriptional response of Medicago truncatula sulphate transporters to arbuscular mycorrhizal symbiosis with and without sulphur stress

2013

Sulphur is an essential macronutrient for plant growth, development and response to various abiotic and biotic stresses due to its key role in the biosynthesis of many S-containing compounds. Sulphate represents a very small portion of soil S pull and it is the only form that plant roots can uptake and mobilize through H(+)-dependent co-transport processes implying sulphate transporters. Unlike the other organically bound forms of S, sulphate is normally leached from soils due to its solubility in water, thus reducing its availability to plants. Although our knowledge of plant sulphate transporters has been growing significantly in the past decades, little is still known about the effect of…

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…

As the frequency of extreme environmental events is expected to increase with climate change, identifying candidate genes for stabilizing the protein composition of legume seeds or optimizing this in a given environment is increasingly important. To elucidate the genetic determinants of seed protein plasticity, major seed proteins from 200 ecotypes of Medicago truncatula grown in four contrasting environments were quantified after one-dimensional electrophoresis. The plasticity index of these proteins was recorded for each genotype as the slope of Finlay and Wilkinson's regression and then used for genome-wide association studies (GWASs), enabling the identification of candidate genes for d…

The pea sulfate transporter, PsSULTR4, contributes to seed yield and quality

2023

To investigate the role of vacuolar sulfate in seed yield and quality, we have targeted the single pea SULTR4 gene (PsSULTR4), which encodes a transporter homologous to Arabidopsis SULTR4;1 and 4;2 that allow sulfate efflux from the vacuole to the cytosol. By simulating the 3D structure of PsSULTR4, we observed that it is similar to that of SULTR4;1 in Arabidopsis. Furthermore, a phylogenetic analysis revealed a high level of conservation of SULTR4 protein motifs across land species. A fluorescent protein fusion experiment confirmed that PsSULTR4 localizes to the vacuolar membrane.Five sultr4 mutants were identified by TILLING (Targeting Induced Local Lesions IN Genomes), two of which showe…

L’objectif de ma thèse est de mettre en évidence les déterminismes génétiques sous-jacents à la teneur et à la composition protéique des graines de légumineuses ainsi qu’à la plasticité de ces composantes vis-à-vis de l’environnement. Afin de répondre à cet objectif, l’approche…

S-34 and N-15 labelling to model S and N flux in plants and determine the different components of N and S use efficiency

2013

International audience; In order to highlight our understanding on ecosystems functioning and resource sharing/competition, either in artificial environment or agrosystems, according to changes in the climatic conditions, it is necessary to measure accurately element fluxes within plants. Stable isotopes allow tracking safely and accurately on a short time frame the behavior of elements in plants. After a short review devoted to isotopic studies of elemental flux within plants, we explain how a direct multiple labelling study might be conducted in a plant, so as to measure over short time nitrogen and sulfur acquisition, and assimilates arising from a labelled source.

Elucidating the genetic determinism of the plasticity of seed proteins in response to the environment using Medicago truncatula

2019

International audience; Legumes are able to produce high-protein seeds without nitrogen fertilizer through root symbiosis with nitrogen-fixing rhizobia. Rich in lysine, these proteins are used for human nutrition and animal feed. However, instability of seed protein yield and quality due to environmental fluctuations limits the wide adoption of legumes in Europe. Breeding efforts are needed to optimize and stabilize seed nutritional quality. We have studied the plasticity of protein content and composition of seeds from a collection of 200 ecotypes of Medicago truncatula grown under four controlled conditions (optimal, drought, and winter/spring sowing). A quantitative analysis of one-dimen…
