Characterization of Pea (Pisum Sativum L.) genes implicated in arbuscular mycorrhiza formation and function
2010
The arbuscular mycorrhizal (AM) association results from a successful interaction between the genomes of the two symbiotic partners. In this context, the aim of my research was to better characterize the role of the late stage symbiosis-related pea genes PsSym36, PsSym33 and PsSym40 in the functional AM (i) by investigating the effect of mutations in the three genes on fungal and plant gene responses and (ii) by creating conditions for the localization of two of the genes, PsSym36 and PsSym40, on the pea genetic map for future map-based cloning. The expression of a subset of ten fungal and eight plant genes,previously reported to be activated during mycorrhiza development, was compared in G…
Diagnosis of non target site based resistance within rye grass(Lolium sp): development of quick and reliable tests
2013
Non target site resistance (NTSR) is the major threat for effective herbicide-based control of grass weeds. NTSR, still largely unknown, is endowed by the regulation of a subset of the genes involved in the response of the weed to herbicide treatment. This study aims at identifying NTSR genes in rye-grass to develop resistance diagnosis tests. The transcriptome of plants resistant or sensitive to ALS inhibitors collected before and after herbicide application was sequenced using a deep sequencing technology. We identified genes differentially expressed between resistant and sensitive plants. We developed a RT-qPCR test to measure gene expression levels in individual plants from several popu…
