The [[anamorph]]s of ''Botryotinia'' are mostly included in the ''[[Deuteromycetes|imperfect fungi]]'' genus '''''Botrytis'''''. The genus contains 22 species and one hybrid. Plant diseases caused by ''Botryotinia'' species appear primarily as blossom [[blight]]s and fruit [[rot]]s but also as leaf spots and bulb rots in the field and in stored products. The fungi induce [[host cell]] death resulting in progressive decay of infected plant tissue, whence they take nutrients. [[Sexual reproduction]] takes place with [[ascospore]]s produced in [[apothecium|apothecia]], [[conidia]] are the means of [[asexual reproduction]]. [[Sclerotium|Sclerotia]] of plano-convexoid shape are typical. Some species also cause [[damping off]], killing seeds or [[seedling]]s during or before [[germination]]. ''[[Botryotinia fuckeliana]]'' (or ''Botrytis cinerea'') is an important species for [[wine]] industry as well as horticulture. Other economically important species include ''[[Botryotinia convoluta]]'' (the [[type species]] of the genus), ''[[Botryotinia polyblastis]]'', ''[[Botrytis allii]]'' and ''[[Botrytis fabae]]''. ==References== *Staats et al.2004[http://mbe.oxfordjournals.org/cgi/content/full/22/2/333] * Synoptic keys to the inoperculate stromatic discomycetes in the Nordic countries[http://biologi.uio.no/bot/ascomycetes/Sclero.key.html#anchor921766] [[Category:Ascomycota]] [[Category:Plant pathogens and diseases]] {{Ascomycetes-stub}} {{plant-disease-stub}} [[de:Botrytis]] [[lt:Kekeras]] ==External links== * [http://www.culturesheet.org/diseases:botrytis Botrytis (gray mould) prevention] on CultureSheet.org
