| geography, plants, and growing systems shape the genetic structure of tunisian botrytis cinerea populations. | botrytis cinerea, considered for a long time as a generalist fungal pathogen of a multitude of plants, was recently shown to exhibit significant population structure in france according to the host, suggesting sympatric specialization. recent models also showed that adaptation to new hosts may facilitate the process of sympatric speciation in fungal plant pathogens. the present work aimed at investigating if host plants, combined with geographic origin and growing systems, shape the diversity an ... | 2008 | 19000001 |
