Higher plants have to cope with fluctuating mineral resource availability. However strategies such as stimulation of root growth, increased transporter activities, and nutrient storage remobilization been mostly studied for only a few macronutrients. Leaves cultivated crops (Zea mays, Brassica napus, Pisum sativum, Triticum aestivum, Hordeum vulgare) tree species (Quercus robur, Populus nigra, Alnus glutinosa) grown under field conditions were harvested regularly during their life span...
Human mineral malnutrition or hidden hunger is considered a global challenge, affecting large proportion of the world’s population. The reduction in content edible plant products frequently found cultivars bred for higher yields, and probably increased by intensive agricultural practices. filling grain with macro micronutrients partly result direct allocation from root uptake remobilization vegetative tissues. aim this bibliographic review to focus on recent knowledge obtained ionomic...
In order to maintain high yields while saving water and preserving non-renewable resources thus limiting the use of chemical fertilizer, it is crucial select plants with more efficient root systems. This could be achieved through an optimization both architecture uptake ability and/or improvement positive plant interactions microorganisms in rhizosphere. The development devices suitable for high-throughput phenotyping structures remains a major bottleneck. Rhizotrons growth controlled...
The cultivation of legumes shows promise for the development sustainable agriculture, but yield instability remains one main obstacles its adoption. Here, we tested whether stability (i.e., resistance and resilience) pea plants subjected to drought could be enhanced by soil microbial diversity. We used a dilution approach manipulate diversity, with genotype distinguish effect symbionts from that diversity as whole. investigated physiology in response when grown on containing high or low...
Throughout tomato domestication, a large increase in fruit size was associated with loss of dry matter and sugar contents. This study aims to dissect the contributions genetic variation physiological processes underlying relationships between growth accumulation sugars. Fruit quality traits parameters were measured on 20 introgression lines derived from Solanum chmielewskii into S. lycopersicum, under high (HL, unpruned trusses) low (LL, trusses pruned one fruit) load conditions. Inter-...
Abstract It has been recently demonstrated, utilizing interspecific introgression lines of tomato, generated from the cross between Solanum lycopersicum and wild species pennellii, that efficiency photosynthate partitioning exerts a considerable influence on metabolic composition tomato fruit pericarp. In order to further evaluate source-sink interaction, metabolite was determined by gas chromatography-mass spectrometry in different population. For this purpose, we used 23 resulting an S....
Water stress and sulfur (S) deficiency are two constraints increasingly faced by crops due to climate change low-input agricultural practices. To investigate their interaction in the grain legume pea (Pisum sativum), sulfate was depleted at mid-vegetative stage a moderate 9-d water period imposed during early reproductive phase. The combination of stresses impeded processes synergistic manner, reducing seed weight number, inducing abortion, which highlighted paramount importance for...
A mechanistic model predicting the accumulation of tomato fruit sugars was developed in order (i) to dissect relative influence three underlying processes: assimilate supply (S), metabolic transformation into other compounds (M), and dilution by water uptake (D); (ii) estimate genetic variability S, M, D. The latter estimated a population 20 introgression lines derived from wild species (Solanum chmielewskii) S. lycopersicum, grown under two contrasted load conditions. Low systematically...
Plant and soil types are usually considered as the two main drivers of rhizosphere microbial communities. The aim this work was to study effect both N availability plant genotype on associated communities, in relation nutritional strategies plant-microbe interactions, for six contrasted Medicago truncatula genotypes. plants were provided with different nutrient solutions varying their nitrate concentrations (0 mM 10 mM). First, influence nitrogen genetic structure bacterial fungal...
Drought stress negatively affects plant growth and productivity. Plants sense soil drought at the root level but underlying mechanisms remain unclear. At cell level, we aim to reveal short-term perception of through membrane dynamics.In our study, 15 Medicago truncatula accessions were exposed a polyethylene glycol (PEG)-induced stress, leading contrasted ecophysiological responses, in particular related architecture plasticity. In reference accession Jemalong A17, identified as susceptible,...
As drought is increasingly frequent in the context of climate change it a major constraint for crop growth and yield. The ability plants to maintain their yield response depends not only on tolerate drought, but also capacity subsequently recover. Post-stress recovery can indeed be decisive resilience stability. Pea (Pisum sativum), as legume, has fix atmospheric nitrogen through its symbiotic interaction with soil bacteria within root nodules. Biological fixation highly sensitive which...
Tomato fruit growth and composition depend on both genotype environment. This paper aims at studying how phenotypic responses to changes in carbon availability can be influenced by genotype, identifying genotype-dependent -independent gene expression underlying variations composition. We grew a parental line (Solanum lycopersicum) an introgression from Solanum chmielewskii harbouring quantitative trait loci for fresh weight sugar content under two loads (FL). Lowering FL increased cell...
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...
Nod factors (NF) are molecules produced by rhizobia which involved in the N2-fixing symbiosis with legume plants, enabling formation of specific organs called nodules. Under drought conditions, nitrogen acquisition N2-fixation is depressed, resulting low productivity. In this study, we evaluated effects NF supply on and cytokinin biosynthesis soybean plants grown under drought. to water stressed soybeans increased CK content all organs. The profile metabolites also shifted from t-Z cis-Z an...
Climate change modifies the dynamics and quantity of plant water supply, morphological response to environmental factors plays a key role in crop-weed interactions. This study investigated interspecies diversity related responses annual herbaceous species stress. Key traits were measured at two growth stages on five weed crop (soft wheat, rapeseed) grown gradient availability greenhouse experiment. For each trait, curves stress defined, their parameters used quantify diversity. Generic...
Rhizodeposition is the export of organic compounds from plant roots to soil. Carbon allocation towards rhizodeposition has be balanced with for other physiological functions, which depend on both newly assimilated and stored nonstructural carbohydrate (NSC). To test whether exudation primary metabolites scales NSC status, we studied diurnal dynamics amino acid (AA) pools fluxes within rhizosphere. These were measured in field under hydroponic-controlled conditions. Further, C-limiting...
Soybean [ Glycine max (L.) Merr] is the legume with largest cultivated area worldwide and its yield depends largely on symbiotic nitrogen fixation root architecture. This study aimed to explore genetic variability of architectural traits di-nitrogen fixing activity in a small collection nine European cultivars belonging same maturity group during their early stages. New image analysis approaches were implemented characterise architecture at high throughput. Significant was identified for...
Legume plants, such as peas, are of significant nutritional interest for both humans and animals. However, plant nutrition thus, seed composition, depends on soil mineral nutrient availability. Understanding the impact their deprivation content, net uptake, remobilization is key importance but remains complex elements ionome linked in intricate networks, one element impacting uptake other nutrients. To get a better insight into pea nutrition, transitory deprivations 13 nutrients were imposed...
