Genetic Diversity Trends in the Cultivated Potato: A Spatiotemporal Overview
15 avril 2022, HE CondorcetCARAHArticle scientifiqueRésumé des auteurs : Monitoring the change in genetic diversity over time and space in crop species is essential to facilitating further improvement. As the world’s most important tuber crop for human consumption, and an ideal candidate to help address global food security, the cultivated potato deserves in-depth study in this regard. In this overview, some aspects of spatiotemporal diversity ... -
In Vitro Dual Culture of Polymyxa betae in Agrobacterium rhizogenes Transformed Sugar Beet Hairy Roots in Liquid Media
23 juin 2011, HE CondorcetArticle scientifique"Polymyxa betae is a soil-borne protist and an obligate parasite of sugar beet that transmits the beet necrotic yellow vein virus. Sugar beet hairy roots, transformed by Agrobacterium rhizogenes, were inoculated with surface-sterilized root fragments infected by P. betae. After 10 wk in a liquid medium, typical structures of P. betae were observed in this in vitro system. This first in vitro culture ... -
