Resumen
- A list of known plant species that serve as hosts of Botrytis spp. is presented. Botrytis species are reported to attack a total of 596 genera of vascular plants (tracheophytes), representing over 1400 plant species, although the host range is most probably much wider since there are limited reports of diseases on wild plants. B. cinerea was found on 586 genera, while the other species have narrower host ranges. Of the 596 genera, the majority (580) belongs to the Spermatophyta, 15 to the Pteridophyta and only 1 to the Lycopodiophyta. In the Spermatophyta, one genus belongs to Cycadophyta (cycads), 18 genera to the Pinophyta (conifers), one genus to the Ginkgophyta (ginkgo), and 562 genera to the Magnoliophyta (also known as flowering plants or Angiospermae). Geographically, Botrytis spp. occur wherever their host plants are grown, ranging from tropical and subtropical areas to cold temperate zones of Northern and Southern globe regions including regions where plants are grown in extreme cold weather or where agriculture is practiced in the desert.
