Ethylene biosynthesis in Botrytis cinerea.
Ethylene is often released during plant pathogenesis. Enhanced ethylene biosynthesis by the attacked plant, and formation of ethylene by the attacking pathogen may be involved. We defined the biosynthetic pathway of ethylene in the pathogenic fungus Botrytis cinerea, and characterized the conditions that affect ethylene production in vitro. During the first 48 h of culture the fungus uses methi...
متن کاملEthylene production by Botrytis cinerea in vitro and in tomatoes.
A laser-based ethylene detector was used for on-line monitoring of ethylene released by the phytopathogenic fungus Botrytis cinerea in vitro and in tomato fruit. Ethylene data were combined with the results of a cytological analysis of germination of B. cinerea conidia and hyphal growth. We found that aminoethoxyvinylglycine and aminooxyacetic acid, which are competitive inhibitors of the 1-ami...
متن کاملInfection Strategies of Botrytis cinerea
Botrytis cinerea is a ubiquitous filamentous fungal pathogen of a wide range of plant species. The fungus is able to infect all aerial parts of its host plants to a certain extent. Infection may cause enormous damage both during plant growth and in the post-harvest phase (during cold storage or transport). B. cinerea is a major cause of economic loss in the production chain of cut flowers, bulb...
متن کاملRipening-regulated susceptibility of tomato fruit to Botrytis cinerea requires NOR but not RIN or ethylene.
Fruit ripening is a developmental process that is associated with increased susceptibility to the necrotrophic pathogen Botrytis cinerea. Histochemical observations demonstrate that unripe tomato (Solanum lycopersicum) fruit activate pathogen defense responses, but these responses are attenuated in ripe fruit infected by B. cinerea. Tomato fruit ripening is regulated independently and cooperati...
متن کاملThe P450 monooxygenase BcABA1 is essential for abscisic acid biosynthesis in Botrytis cinerea.
The phytopathogenic ascomycete Botrytis cinerea is known to produce abscisic acid (ABA), which is thought to be involved in host-pathogen interaction. Biochemical analyses had previously shown that, in contrast to higher plants, the fungal ABA biosynthesis probably does not proceed via carotenoids but involves direct cyclization of farnesyl diphosphate and subsequent oxidation steps. We present...
