Medicago truncatula is a model for investigating legume genetics, including the genetics and evolution of legume–rhizobia symbiosis. We used whole-genome sequence data to identify characterize polymorphisms linkage disequilibrium (LD) in diverse collection 26 M. accessions. Our analyses reveal that harbors both higher diversity less LD than soybean ( Glycine max ) exhibits patterns recombination similar Arabidopsis thaliana . The population-scaled rate approximately one-third mutation rate,...
Abstract Zero hunger and good health could be realized by 2030 through effective conservation, characterization utilization of germplasm resources 1 . So far, few chickpea ( Cicer arietinum ) accessions have been characterized at the genome sequence level 2 Here we present a detailed map variation in 3,171 cultivated 195 wild to provide publicly available for genomics research breeding. We constructed pan-genome describe genomic diversity across its progenitor accessions. A divergence tree...
Legume roots show a remarkable plasticity to adapt their architecture biotic and abiotic constraints, including symbiotic interactions. However, global analysis of miRNA regulation in is limited, view the evolution miRNA-mediated diversification different ecotypes lacking. In model legume Medicago truncatula, we analyze small RNA transcriptome submitted pathogenic Genome mapping computational pipeline identify 416 candidates, known novel variants 78 families present miRBase. Stringent...
Verticillium wilt is a major threat to alfalfa (Medicago sativa) and many other crops. The model legume Medicago truncatula was used as host for studying resistance susceptibility albo-atrum. In addition presenting well-established genetic resources, this wild plant species enables investigate biodiversity of the response pathogen putative crosstalk between disease symbiosis. Symptom scoring after root inoculation modelling curves allowed assessing levels in recombinant lines three crosses...
Lotus japonicus is a well-studied nodulating legume and model organism for the investigation of plant-microbe interactions. The majority transcriptome studies have focused on interactions with compatible symbionts, whereas responses to non-adapted rhizobia pathogenic bacteria not been well characterised. In this study, we first characterised transcriptomic response L. its symbiont, Mesorhizobium loti R7A, through RNA-seq analysis various plant tissues. Early symbiotic signalling was largely...
Plant resistance to pathogens is commonly associated with a hypersensitive response (HR), but the degree which HR responsible for incompatibility subject debate. Resistance aphids likely share features less well understood. Here, we report effective pea aphid Acyrthosiphon pisum in Medicago truncatula. Aphids lost weight and died rapidly (within two days) on resistant genotype Jemalong, developed necrotic lesions following infestation. Lesions were induced by nonvascular intracellular stylet...
Elevated temperature and humidity are major environmental factors limiting crop yield distribution. An understanding of the mechanisms underlying plant tolerance to high may facilitate development cultivars adaptable warm or humid regions. Under conditions 90% 35 °C, thermotolerant Portulaca oleracea exhibits excellent photosynthetic capability relatively little oxidative damage. To determine proteomic response that occurs in leaves P. following exposure humidity, a approach was performed...
Summary Ralstonia solanacearum is a major soilborne pathogen that attacks > 200 plant species, including crops. To characterize Mt QRRS 1 , quantitative trait locus ( QTL ) for resistance towards this bacterium in the model legume Medicago truncatula genetic and functional approaches were combined. analyses together with disease scoring of heterogeneous inbred families used to define locus. The candidate region was studied by physical mapping using bacterial artificial chromosome BAC...
Global warming is expected to have a direct impact on plant disease patterns in agro-eco-systems. However, few analyses report the effect of moderate temperature increase severity due soil-borne pathogens. For legumes, modifications root plant-microbe interactions either mutualistic or pathogenic climate change may dramatic effects. We investigated increasing quantitative resistance Verticillium spp., major fungal pathogen, model legume Medicago truncatula and crop M. sativa. First, twelve...
Demand response (DR) programs currently cover about 2\% of the average annual global demand, which is far from contributing to International Energy Agency's ``Net Zero by 2050'' roadmap's 20\% target. While aggregation many small flexible loads such as individual households can help reaching this target, increasing participation industries that are major electricity consumers certainly a way forward. The indoor agriculture sector experiences significant growth partake in sustainable...
<title>Abstract</title> Background Genotype-by-sequencing (GBS) is a cost-effective method for large-scale genotyping, widely used across various species, particularly those with large genomes. A critical aspect of GBS lies in the selection restriction enzymes genome digestion and optimization data analysis pipelines. However, few studies have comprehensively examined combined effects enzyme choice pipeline configuration. Results In this study, we created libraries using three commonly...
Environmental changes challenge plants and drive adaptation to new conditions, suggesting that natural biodiversity may be a source of adaptive alleles acting through phenotypic plasticity and/or micro-evolution. Crosses between accessions differing for given trait have been the most common way disentangle genetic environmental components. Interestingly, such man-made crosses combine never meet in nature. Another discover alleles, inspired by evolution, is survey large ecotype collections...
Resistance mechanisms to Verticillium wilt are well studied in tomato, cotton and Arabidopsis, but much less legume plants. Because plants establish nitrogen-fixing symbioses their roots, resistance root-attacking pathogens merits particular attention. The interaction between the soil-borne pathogen alfalfae model Medicago truncatula was investigated using a resistant (A17) susceptible (F83005.5) line. As shown by histological analyses, colonization initiated similarly both lines. Later on,...
The infection of the model legume Medicago truncatula with Ralstonia solanacearum GMI1000 gives rise to bacterial wilt disease via colonisation roots. root and leaf responses early (1 3 days post infection) were characterised investigate molecular mechanisms plant resistance or susceptibility. A proteomics approach based on pools susceptible resistant recombinant inbred lines was used specifically target for tolerance. Differential abundances evidenced proteins involved in defence (e.g.,...
V erticillium albo‐atrum is responsible for considerable yield losses in many economically important crops, among them alfalfa ( M edicago sativa ). Using truncatula as a model studying resistance and susceptibility to . , previous work has identified genetic variability major quantitative trait loci QTL s) In order study the control of non‐legume isolate this pathogen, population recombinant inbred lines RIL from cross between resistant line F83005.5 susceptible A17 was inoculated with...
Oleic acid is a monounsaturated fatty increasing oil oxidative stability. High content of oleic thus valuable trait in oilseed crops. Sunflower ( Helianthus annuus L.) normally accumulates linoleic as major acid, but mutant expressing high phenotype form was previously obtained by chemical mutagenesis and mapped on the sunflower genome. Several studies suggest presence additional genes involved control with their expression possibly depending genetic background. To test this hypothesis, we...
