Texte intégralCorn poppy (Papaver rhoeas) is a very widespread cosmopolitan weed in winter crops cereal in Europe which has a high potential for invasion and spread in crops. It is mainly controlled by ALS inhibitor herbicides and auxin herbicides. The intensive use of these two modes of action has led to the evolution of resistance in many poppy populations across Europe. Herbicide resistance involves two categories of mechanisms: target-site-based resistance (TSR) and non-target-site-based resistance (NTSR). In poppy, only NTSR mechanisms have been identified, but the specific genes remain unknown. This work therefore has several goals: (i) identify and potentially validate the genetic determinants of resistance to auxin herbicides in corn poppy and (ii) evaluate resistance status to auxin herbicides in French poppy populations.In a first part, we phenotypically characterized the plant material available using herbicides sensitivity bioassays (Chapter 1) to assess the resistance status of poppies to auxin herbicides in France. We have shown that resistance to 2,4-D in France was widespread, even very well established in certain areas. We also identified two areas in Italy and Greece where resistant plants to halauxifen-methyl were detected, suggesting the beginning of the evolution of resistance to this new synthetic herbicide. Populations with a balanced ratio of resistant and sensitive individuals were used for plant material production for the molecular biology approaches of the second part.In a second part, we studied constitutive resistance to 2,4-D and halauxifen-methyl among 14 populations via RNA sequencing (RNAseq) (Chapter 2). We showed that the expression profiles of sensitive and resistant plants were specific to each population. Among the genes differentially expressed in resistant plants, some gene families potentially involved in the metabolism of herbicides (CYP450, GST, ABC transporters, etc.) or regulatory cascades (transcription factors, protein kinases) have been identified. Based on these results, the expression level of these genes was validated via an RT-qPCR approach using a larger sample of plants. All the results indicate that there is potentially a wide variety of inter- and intra-population resistance mechanisms.The second RNAseq (Chapter 3) aimed to study the transcriptomic response of resistant and sensitive plants between 4h and 48h after the application of 2,4-D in two populations. We identified a large diversity of genes and gene families specifically induced in resistant plants from both populations, but their role in resistance could not be verified. As in constitutive resistance, these can potentially be detoxification enzymes, transporters, or even potential auxin target genes or genes associated with the general stress response. In addition, 2,4-D induces a rapid response which is detectable within 4 hours following treatment regardless of the phenotype and population.Finally, the comparison of constitutively differentially expressed genes between the two RNAseq approaches demonstrates that the absence of common genes is potentially due to a high diversity of intra- and -inter population resistance mechanisms, or to the fact that the mechanisms that contribute the most to resistance are due to structural mutations

Texte intégralIsoprenoids represent important cell constituents synthesized in many living organisms. ln plants, isoprenoid biogenesis occurs in three compartments : plastids, the endoplasmic reticulum-cytosol and mitochondrie.We focused on the molecular and functional studies of the role of Iwo cytosolic isoprenoids ( dolichol andsterol) in the development of plants. The key Io our strategy is the targeted silencing of specific Arabidopsis genes using the RNAi technology (knockdown) and the identification of T-DNA insertion mutants (knockout). ln the first chapter, we show that isoprenoids are involved indirectly in protein N-glycosylation via Dolichol P-Mannose derived from dolichol phosphate mannose synthase (DPMS). We demonstrate that plant DPMSis organized as a heteromeric enzyme complex localized in the endoplasmic reticulum (ER) and consists of DPMS1 acting as the catalytic core and two interacting subunits DPMS2 and DPMS3. The DPMS1-RNAiand dpms1 lines display an altered N-glycosylation pattern and exhibit extensive chlorosis, strong inhibition of root growth and hypersensitivity to ammonium. These phenotypic defects are associated with an «unfolded protein response» in the ER. These data demonstrate that the DPMS genes are essential for the protein N-glycome and plant development. ln the second chapter, we focused on the potentiel roles of sterol biosynthetic intermediates (SBls) in plant development using ERG28 protein, a component of the sterol C-4 demethylation (SC4DM) complex, as a target. We demonstrate that ERG28 is localized in ER and tethers 3 enzymes, sterol 4alpha-methyl oxidase, 4alpha carboxysterol-C3-dehydrogenase/C4- decarboxylase and sterone ketoreductase. We show that the Arabidopsis ERG28-RNAi and erg28 lines develop the hallmarks of altered polar auxin transport (PAT) including the differentiation of pin-like inflorescences, the loss of apical dominance, leaf fusion and inhibition root growth. The observed phenotypes correlate with the accumulation of methylene-cycloartanol-4-carboxy-4-methyl, a cryptic SBI. Our data provide a new level of interaction between sterols and auxin
