QuaRVeg

Carrot is the most widely consumed root vegetable worldwide. Because of its fibers and its carotenoid high accumulating organs it is often recommended for a healthy diet. In France, it is a very economically important species both in vegetable (2nd vegetable product in France) and seed (France shares with US the position of world leaders) production. Constantly seeking higher performance, the carrot sector’s players wonder about nutritional quality and fungicide use reduction.

QuaRVeg main purpose focuses on two topics that are the determinism of carotenoid accumulation in a taproot and mechanisms involved in partial resistance. For the first, the central question is to understand how is controlled the accumulation of carotenoids in carrots? For the latter, efforts are concentrated on Alternaria dauci (Ad), responsible for the most damaging foliar disease on this species, aiming to find which components of the host and pathogen determine the resistance to A. dauci. As a support to these studies, QuaRVeg also investigates the diversity extent and structure within wild and cultivated genetic resources. The programs combine several complementary approaches such as fine phenotyping (biochemical and sensory analyses), genetic control analysis (association genetics and QRLs analysis), gene expression analysis and functioning of biosynthetic pathways.

L'équipe QuaRVeg

All QuaRVeg staff is either from University of Angers or from Agrocampus ouest, all of them are invested in research as well as in teaching activities at all levels. QuarVeg is also invested in life-long learning as well as in distant e-learning, and in European courses. Main scopes of teaching are genetics, genetic diversity, plant–pathogen interactions, disease resistance, biochemistry, product quality, post-harvest, biotechnology, experimental designs and statistics, fruit and vegetable cropping systems, mediterranean and tropical horticulture, urban and periruban horticulture, organic horticulture, horticulture in developing countries.
