Les "mots" de la résistance

2020

Avant d'entamer le dossier, voici un petit glossaire à l'usage des gestionnaires de la résistance aux produits phytopharmaceutiques.La résistance aux PPP est un phénomène souvent complexe, faisant appel à des notions de biochimie, génétique, sciences de l’évolution. De ce fait, pour apprécier au mieux les articles de ce dossier, il apparaît utile d’avoir sous la main un mémento donnant une définition scientifique des termes les plus courants.

Une première à Avignon, les JÉR, journées d'échanges sur les résistances

2014

Pour le professionnel du conseil à l'utilisation de produits de protection des plantes, il n'est pas toujours évident d'accéder aux connaissances scientifiques sur les résistances à ces produits (cas de résistance, mécanismes d'évolution, stratégies de gestion de résistances...). Pour le scientifique, il n'est pas toujours facile d'avoir une vue actualisée de la situation au champ (problèmes émergents, questions que se posent les professionnels...). La solution ? Les JÉR, dont le but est de permettre un dialogue direct entre recherche et " terrain " !

Isolation and characterization of a Vitis vinifera transcription factor, VvWRKY1, and its effect on responses to fungal pathogens in transgenic tobac…

2007

International audience; Pathogen attack represents a major problem for viticulture and for agriculture in general. At present, the use of phytochemicals is more and more restrictive, and therefore it is becoming essential to control disease by having a thorough knowledge of resistance mechanisms. The present work focused on the trans-regulatory proteins potentially involved in the control of the plant defence response, the WRKY proteins. A full-length cDNA, designated VvWRKY1, was isolated from a grape berry library (Vitis vinifera L. cv. Cabernet Sauvignon). It encodes a polypeptide of 151 amino acids whose structure is characteristic of group IIc WRKY proteins. VvWRKY1 gene expression in …

Genetic Transformation of Serratula tinctoria (Dyer’s Savory) for Ecdysteroid Production

1999

Serratula tinctoria is a perennial plant of the Compositae family with medium-sized, serrated leaves and purple flowers (Loste 1937). This plant, also known as dyer’s savory, is widespread in Europe but with an irregular distribution. Inflorescences (capitula) are purple and are usually unisexual, staminate, or pistillate. In Europe, the flowering period extends from July to September. More than 40 species have been described in Europe, North Africa, and Asia. The plants produce large amounts of secondary metabolites, in particular ecdysteroids at very high concentration in roots (up to 2% dry wt.), in flowers, and in leaves (Bathori et al. 1986; Rudel et al. 1992; Corio-Costet et al. 1993b…

Chenopodium album L. (Fat Hen): In Vitro Cell Culture, and Production of Secondary Metabolites (Phytosterols and Ecdysteroids)

The name Chenopodium is derived from the Greek words chenos (goose) and podos (foot), because the leaves often resemble goose feet. This genus consists of ca. 120 species, widely distributed over the world, 45 of which have been described in India.

Serratula tinctoria (L.) (Dyer's savory): In vitro culture and the production of ecdysteroids and other secondary metabolites

1996

The name Serratula is derived from the Latin word serra, which means saw. It designates perennial plants of the Compositae family with medium-sized, serrated leaves and purple flowers (Loste 1937). More than 40 species have been described in Europe, North Africa, and Asia. The most common is Serratula tinctoria, also known as dyer’s savory. This species, 30 to 80 cm high, grows on all kind of soils, and is widely distributed in central and northern Europe (synonym: Carduus tinctoria, Scop; French name: serratule des teinturiers; German name: Faberscharte). In France, for example, Serratula tinctoria is widespread but with an irregular distribution, rare in the north and near the Mediterrane…

Sterol and ecdysteroids profiles of Serratula tinctoria (L.) : plant and cell cultures producing steroids

1993

Abstract Cell suspension cultures have been obtained from Serratula tinctoria, a plant producing ecdysteroids. Sterol profiles and ecdysteroid contents have been analysed and compared in plants and cell cultures. In particular, the composition of free and esterified sterols was investigated using appropriate analytical techniques. In plants, esterified sterols were more abundant (50–70% of the total sterol) than in cell cultures (13–36%). A selectivity for sterol esterification was noted: in plants, the triterpenes (as amyrins) were esterified, whereas it was the 4-desmethylsterols (sitosterol and cholesterol) in cell cultures. Ecdysteroids were present in higher quantities in plant (0.1–1.…

Effects of the ingestion ofSerratula tinctoria extracts, a plant containing phytoecdysteroids, on the development of the vineyard pestLobesia botrana…

1997

We describe here the effects of extracts from Serratula tinctoria, a plant producing phytoecdysteroids, on the growth and development of Lobesia botrana, an economically important pest in vineyards. Leaves, hairy roots, or semi-purified (by Sep-Pak procedure) methanolic extracts from this plant were incorporated into an artificial diet given to insects. Larval growth, mortality, weight, and sex-ratio were investigated, as well as sterol and ecdysteroid contents. Experimental diets induced an important mortality in the first, second, and third larval instars, but also in pupae. As males appeared more sensitive to extracts, sex ratio was significantly modified on experimental diets (particula…
