الوصف: Abstract The French government has supported as part of its “Investments for the Future” program a 9‐year research project, PeaMUST, devoted to pea and to a lesser extent, faba bean improvement. Focusing on the main causes of yield irregularity that limit pea and faba bean cultivation, an integrated approach, including molecular exploitation of the pea genome sequence, was applied to identify and incorporate favorable alleles and allele combinations in prebreeding material.

الوصف: Pea forms symbiotic nodules with Rhizobium leguminosarum sv. viciae (Rlv). In the field, pea roots can be exposed to multiple compatible Rlv strains. Little is known about the mechanisms underlying the competitiveness for nodulation of Rlv strains and the ability of pea to choose between diverse compatible Rlv strains. The variability of pea-Rlv partner choice was investigated by co-inoculation with a mixture of five diverse Rlv strains of a 104-pea collection representative of the variability encountered in the genus Pisum. The nitrogen fixation efficiency conferred by each strain was determined in additional mono-inoculation experiments on a subset of 18 pea lines displaying contrasted Rlv choice. Differences in Rlv choice were observed within the pea collection according to their genetic or geographical diversities. The competitiveness for nodulation of a given pea-Rlv association evaluated in the multi-inoculated experiment was poorly correlated with its nitrogen fixation efficiency determined in mono-inoculation. Both plant and bacterial genetic determinants contribute to pea-Rlv partner choice. No evidence was found for co-selection of competitiveness for nodulation and nitrogen fixation efficiency. Plant and inoculant for an improved symbiotic association in the field must be selected not only on nitrogen fixation efficiency but also for competitiveness for nodulation.

الوصف: Combining plant genetic resistance with architectural traits that are unfavorable to disease development is a promising strategy for reducing epidemics. However, few studies have identified root system architecture (RSA) traits with the potential to limit root disease development. Pea is a major cultivated legume worldwide and has a wide level of natural genetic variability for plant architecture. The root pathogen Aphanomyces euteiches is a major limiting factor of pea crop yield. This study aimed to increase the knowledge on the diversity of loci and candidate genes controlling RSA traits in pea and identify RSA genetic loci associated with resistance to A. euteiches which could be combined with resistance QTL in breeding. A comparative genome wide association (GWA) study of plant architecture and resistance to A. euteiches was conducted at the young plant stage in a collection of 266 pea lines contrasted for both traits. The collection was genotyped using 14,157 SNP markers from recent pea genomic resources. It was phenotyped for ten root, shoot and overall plant architecture traits, as well as three disease resistance traits in controlled conditions, using image analysis. We identified a total of 75 short-size genomic intervals significantly associated with plant architecture and overlapping with 46 previously detected QTL. The major consistent intervals included plant shoot architecture or flowering genes (PsLE, PsTFL1) with putative pleiotropic effects on root architecture. A total of 11 genomic intervals were significantly associated with resistance to A. euteiches confirming several consistent previously identified major QTL. One significant SNP, mapped to the major QTL Ae-Ps7.6, was associated with both resistance and RSA traits. At this marker, the resistance-enhancing allele was associated with an increased total root projected area, in accordance with the correlation observed between resistance and larger root systems in the collection. Seven additional intervals associated with plant architecture overlapped with GWA intervals previously identified for resistance to A. euteiches. This study provides innovative results about genetic interdependency of root disease resistance and RSA inheritance. It identifies pea lines, QTL, closely-linked markers and candidate genes for marker-assisted-selection of RSA loci to reduce Aphanomyces root rot severity in future pea varieties.

الوصف: International audience; L’avancée des technologies « nouvelle génération » de séquençage de l’ADN permettent une connaissance de plus en plus poussée des génomes et de leur expression. Ces connaissances permettent d’approcher plus finement les déterminants moléculaires des traits phénotypiques et ouvrent des perspectives d’augmentation du progrès génétique dans le cadre de la sélection variétale. Le pois est une espèce modèle depuis les travaux de G. Mendel conduisant à la découverte des lois de l’hérédité. La séquence du génome de cette espèce longtemps délaissée des approches de génomique a récemment été obtenue par un consortium international piloté par l’INRAE (1,2). Dans le cadre du projet de recherche français PeaMUST regroupant un large partenariat entre secteurs public et privé, différentes stratégies tirant partie de ces connaissances ont été mises en oeuvre pour améliorer le pois (3). Ces stratégies varient en fonction des caractères ciblés : pour améliorer la régularité du rendement, un trait hautement multifactoriel qui résulte de la capacité des plantes à s'adapter et à répondre à l'environnement, une approche de sélection à l’échelle du génome entier a été testée ; pour la résistance durable aux pathogènes, une stratégie prometteuse est de pyramider plusieurs gènes de résistance correspondant à des mécanismes divers ; enfin, des mutations à effet majeur contrôlant l’architecture aérienne et racinaire des plantes ont été testées pour leur effet sur la tolérance aux stress. L'amélioration des cultures doit en effet plusieurs réussites remarquables à la manipulation de l'architecture végétale, comme l'utilisation des caractères afila et de nanisme chez le pois.PeaMust is an international program on pea breeding goals and techniques and pea genomics. Two convergent achievements testify to its pertinence. It associates the complete sequencing and deciphering of the DNA on one hand with efficient genetic approaches to phenotype analysis and methods dealing with quantitative and adaptative traits on the other. Examples of PeaMust successbear on regularity of production, on the confrontation with pathogens or environmental stress, on the architecture of the plant. In each case PeaMust offers innovative opportunities.

الوصف: International audience; Plant systemic signaling pathways allow the integration and coordination of shoot and root organ metabolism and development at the whole-plant level depending on nutrient availability. In legumes, two systemic pathways have been reported in the Medicago truncatula model to regulate root nitrogen-fixing symbiotic nodulation. Both pathways involve leucine-rich repeat receptor-like kinases acting in shoots and proposed to perceive signaling peptides produced in roots depending on soil nutrient availability. In this study, we characterized in the M. truncatula Jemalong A17 genotype a mutant allelic series affecting the Compact Root Architecture2 (CRA2) receptor. These analyses revealed that this pathway acts systemically from shoots to positively regulate nodulation and is required for the activity of carboxyl-terminally encoded peptides (CEPs). In addition, we generated a double mutant to test genetic interactions of the CRA2 systemic pathway with the CLAVATA3/EMBRYO SURROUNDING REGION peptide (CLE)/Super Numeric Nodule (SUNN) receptor systemic pathway negatively regulating nodule number from shoots, which revealed an intermediate nodule number phenotype close to the wild type. Finally, we showed that the nitrate inhibition of nodule numbers was observed in cra2 mutants but not in sunn and cra2 sunn mutants. Overall, these results suggest that CEP/CRA2 and CLE/SUNN systemic pathways act independently from shoots to regulate nodule numbers.

الوصف: Prod 2019-88l BAP GEAPSI INRA DOCT; National audience; Major diseases and pests, such as root rots, ascochyta blights and aphids, are limiting factors to cool season pulse production in many countries worldwide, especially in Europe. In the context of pesticide reduction, plant genetic resistance and architecture are main traits that can be mobilised in breeding for disease and pest management. Knowledge of quantitative resistance to major diseases and pests of pea and faba bean in France has benefited from the development of sequenced genomes and massive SNP markers [1], which have recently been highly valuable to identify candidate genes controlling resistance. Fine mapping and sequencing of major resistance QTL [2], as well as Linkage Analysis (LA) [3] and Genome-Wide Association Studies (GWAS) coupled with Genotyping By Sequencing (GBS) technologies, have been developed to identify, compare and study synteny of loci and candidate genes for resistance. Plant and canopy architectures have been studied in pea for their effect on limiting disease severity and epidemics. Alleles at genes controlling aerial or root plant architectural traits were found to cosegregate with resistance alleles at QTL controlling aerial or root diseases [4]. Combining plant resistance and architecture traits unfavourable to diseases and pests will be a key strategy for durable crop protection. Future research will combine other plant traits with resistance and architecture, such as plant ability to select useful micro-organisms or to produce compounds that are beneficial to plant protection, as well as agricultural practices.

الوصف: International audience; Pea forms symbiotic nodules with Rhizobium leguminosarum sv. viciae (Rlv). In the field, pea roots can be exposed to multiple compatible Rlv strains. Little is known about the mechanisms underlying the competitiveness for nodulation of Rlv strains and the ability of pea to choose between diverse compatible Rlv strains. The variability of pea-Rlv partner choice was investigated by co-inoculation with a mixture of five diverse Rlv strains of a 104-pea collection representative of the variability encountered in the genus Pisum. The nitrogen fixation efficiency conferred by each strain was determined in additional mono-inoculation experiments on a subset of 18 pea lines displaying contrasted Rlv choice. Differences in Rlv choice were observed within the pea collection according to their genetic or geographical diversities. The competitiveness for nodulation of a given pea-Rlv association evaluated in the multi-inoculated experiment was poorly correlated with its nitrogen fixation efficiency determined in mono-inoculation. Both plant and bacterial genetic determinants contribute to pea-Rlv partner choice. No evidence was found for co-selection of competitiveness for nodulation and nitrogen fixation efficiency. Plant and inoculant for an improved symbiotic association in the field must be selected not only on nitrogen fixation efficiency but also for competitiveness for nodulation.

الوصف: BAP GEAPSI INRA; International audience; Plant architecture can contribute to decrease plant susceptibility to pathogens by favoring mechanisms leading to infection escape or increased tolerance. Combining genetic resistance with architectural traits that can negatively impact disease development is thus a strategy of great interest to reduce epidemics. Until now, most strategies exploiting plant architecture have focused on the aerial parts of plants. Few studies have been done on the identification of root system architecture (RSA) traits limiting root disease development and even less on their use in breeding. Aphanomyces euteiches, a soil-borne pathogen infecting roots, is a major limiting factor of pea crop yield. Consistent quantitative trait loci controlling partial resistance were identified in this species [1,2], and other studies reported its RSA as highly variable and under polygenic control [3]. However, the contribution of RSA to resistance to A. euteiches has not yet been explored in pea. To identify common loci controlling RSA and resistance to A. euteiches, we performed a genome wide association (GWA) study using a collection of 266 pea lines contrasted for root architecture or Aphanomyces root rot resistance. The study used recent 14,157 Single Nucleotide Polymorphism resources developed in pea [4,5]. The collection was phenotyped in controlled conditions and using image analysis. The GWA study identified precise genomic regions controlling RSA and common loci associated with resistance to A. euteiches, opening prospects in mining RSA loci in breeding to limit Aphanomyces root rot severity on pea.
