Bacterial rhamnolipids are novel MAMPs conferring resistance to Botrytis cinerea in grapevine

2009

International audience; Rhamnolipids produced by the bacteria Pseudomonas aeruginosa are known as very efficient biosurfactant molecules. They are used for a wide range of industrial applications, especially in food, cosmetics and pharmaceutical formulations as well as in bioremediation of pollutants. In this paper, the role of rhamnolipids as novel molecules triggering defence responses and protection against the fungus Botrytis cinerea in grapevine is presented. The effect of rhamnolipids was assessed in grapevine using cell suspension cultures and vitro-plantlets. Ca2+ influx, mitogen-activated protein kinase activation and reactive oxygen species production form part of early signalling…

Evaluation in vitro du potentiel anthelminthique de la graine de lupin, Lupinus spp.

2015

National audience; Le lupin, protéagineux déjà utilisé en nutrition animale, contient des alcaloïdes qui pourraient avoir des vertus anthelminthiques. Notre étude s’attache à valider et quantifier ces propriétés par des tests in vitro exposant Haemonchus contortus, strongle parasite de ruminants, à différents extraits de deux variétés, riche (amère) ou pauvre (douce) en alcaloïdes. L’analyse des alcaloïdes présents a révélé une teneur plus élevée dans la variété amère (3.3% contre 0.04% dans la variété douce), mais une diversité supérieure dans la variété douce (n=5 contre 3 dans la variété amère). Les différents extraits des variétés testées ont paralysé significativement les stades larvai…
