A proteomic approach to studying plant response to crenate broomrape (Orobanche crenata) in pea (Pisum sativum)
Abstract Crenate broomrape ( Orobanche crenata ) is a parasitic plant that threatens legume production in Mediterranean areas. Pea ( Pisum sativum ) is severely affected, and only moderate levels of genetic resistance have so far been identified. In the present work we selected the most resistant accession available (Ps 624) and compared it with a susceptible (Messire) cultivar. Experiments were performed by using pot and Petri dish bioassays, showing little differences in the percentage of broomrape seed germination induced by both genotypes, but a significant hamper in the number of successfully installed tubercles and their developmental stage in the Ps 624 compared to Messire. The prote…
A new journal on the legume research horizon - Legume Perspectives; Legume Perspectives Editorial Board
International audience; Through the decades of research on various legume species and crops worldwide, its results have been published in an endless number of national and international journals and magazines dealing with various topics. It is certain that the articles on genetics, propelled by Mendel’s pioneering work, are among the most numerous, but it is also true that those on agronomy, agro-ecology, or stress tolerance were produced rather abundantly. So far, there has not been a journal devoted specifically to legume science, except Legume Research published by the Agricultural Research Communication Centre, India. We have published our articles in several crop-specific journals, suc…
Grass Pea
Grass pea (Lathyrus. sativus L.) is an annual legume crop with high protein content and remarkable resistance to extreme environmental conditions, including fl ooding, drought, salinity and low soil fertility, and a signifi cant degree of resistance to biotic stress agents. It is rightly considered one of the most promising sources of calories and protein for the vast and expanding populations of drought-prone and marginal areas of Asia and Africa and as an interesting alternative for cropping systems diversifi cation in marginal lands in Europe, Australia and America. It is a dual purpose crop with great agronomic potential as a grain and forage legume. Nevertheless, as a result of the lit…
Identification of QTLs controlling resistance to rust, aphid and weevil in wild peas by DArTseq SNP-based technology

Differential expression proteomics to investigate responses and resistance to Orobanche crenata in legumes
International audience; In order to study the plant response to parasitic plants and the molecular basis of the resistance we have used a proteomic approach. The root proteome of two accessions of the model legume Medicago truncatula and crop pea displaying differences in their resistance phenotype, in control as well as in infected plants have been compared. We report quantitative as well as qualitative differences in the two-dimensional gel electrophoresis (2-DE) maps between plant genotypes and treatments (control, non-infected, and infected). Differential spots spots were successfully identified by peptide mass fingerprinting (PMF) following MALDI-TOF mass spectrometry. Many of the prot…

Legumes and the environment
Prod 2017-358a BAP GEAPSI INRA; International audience; The ability of legumes to fix atmospheric nitrogen gives them a crucial role in sustainable farming systems. Their presence can provide several other valuable ecological services. In Europe these assets have been neglected whilst developing highinput farming systems for maximizing yields. Diverse strategies are presented for maximizing ecological services provided by legumes in order to re-integrate them in cropping systems. Key words: Inputs, intercrop, ecological services, mineralization, weeds, N-fixation, value chain The second plenary session of the International Legume Society conference was dedicated to talks on “Legume and envi…
