Characterization of two groups of Spodoptera exigua Hübner (Lepidoptera: Noctuidae) C-type lectins and insights into their role in defense against th…
2018
Insect innate immunity relies on numerous soluble and membrane-bound receptors, named pattern recognition proteins (PRPs), which enable the insect to recognize pathogen-associated molecular patterns. C-type lectins are among the best-studied PRPs and constitute the most diverse family of animal lectins. Here we have characterized two groups of Spodoptera exigua C-type lectins that differ in their phylogeny, domain architecture, and expression pattern. One group includes C-type lectins with similar characteristics to other lepidopteran lectins, and a second group includes bracoviral-related lectins (bracovirus-like lectins, Se-BLLs) recently acquired by horizontal gene transfer. Subsequently…
Soybean and casein hydrolysates induce grapevine immune responses and resistance against Plasmopara viticola
2014
International audience; Plasmopara viticola, the causal agent of grapevine downy mildew, is one of the most devastating grape pathogen in Europe and North America. Although phytochemicals are used to control pathogen infections, the appearance of resistant strains and the concern for possible adverse effects on environment and human health are increasing the search for alternative strategies. In the present investigation, we successfully tested two protein hydrolysates from soybean (soy) and casein (cas) to trigger grapevine resistance against P. viticola. On Vitis vinifera cv. Marselan plants, the application of soy and cas reduced the infected leaf surface by 76 and 63%, as compared to th…

Unité et scissions dans l’histoire de la CGT
2019
National audience; La question de l’unité tient une place particulière dans l’histoire de la CGT dans la mesure où elle est l’exception qui confirme la règle. En dehors des périodes 1895-1921, 1936-39 et 1943-47, la spécificité du syndicalisme confédéré réside dans sa division et son éclatement. Sur plus de 120 ans d’existence, la CGT n’a connu l’unité organique que durant une trentaine d’années (soit ¼ de son histoire). La division, ou le pluralisme si l’on préfère, est en somme la situation « normale » du syndicalisme français.Ce chapitre propose donc de comprendre les raisons et les processus qui ont conduit à cet état de dispersion ; et inversement, d’analyser les facteurs qui ont rendu…
Study of the role of the CDC48 chaperone protein in plant immunity
2018
The chaperone protein CDC48 (Cell division cycle 48) is a major regulator of the quality control of proteins and is involved in various cellular processes in animals and yeast. In contrast, the role of CDC48 in plants is poorly known. In the present work, we investigated the function of CDC48 in plant immunity thanks to the cryptogein/tobacco biological model, cryptogein being produced by the oomycete phytophthora cryptogea.Three strategies were carried out. First, the dynamic of accumulation CDC48 together with intracellular events inherent to the immune response were analyzed in both wild-type and CDC48 overexpressing tobacco cells (CDC48-TAP line). Second, a list if CDC48 partners was es…

Identification of the cell-wall derived xyloglucan as a new damage-associated molecular pattern (DAMP) eliciting plant immunity in Vitis vinifera and…
2018
Activation of the plant immune responses requires recognition of common pathogen-associated molecular pattern (PAMP) by their cognate pattern recognition receptors (PRR). Chitin, a major component of fungal cell walls, is a well-known PAMP that triggers defense responses in several mammal and plant species.In the first part of this study, we show that two chitooligosaccharides, chitin and chitosan, act as PAMPs in grapevine (Vitis vinifera) as they elicit immune signaling events, defense gene expression, and resistance against pathogens. These two PAMPs are active in grapevine suggesting that at least one perception system exists. Phylogenetic analysis clearly distinguished three V. vinifer…
