Occurrence of Botrytis Crown Rot Caused by Botrytis cinerea in Lettuce in Southern New Mexico

Symptomless, Systemic, and Seedborne Infection of Lettuce by Botrytis Cinerea

Three new metabolites from Botrytis cinerea.

Three new metabolites, gamma-abscisolactone (1), botrytisic acids A (3) and B (4) were isolated from the fermentation broth of Botrytis cinerea TB-3-H8. Their structures were elucidated on the basis of MS, IR, UV, and NMR spectroscopic data. Compound 2 was isolated from natural resource for the first time. The structure of 1 was further confirmed by single-crystal X-ray diffraction (CCDC-265897).

Occurrence of Narcissus Smoulder Caused by Botrytis narcissicola in Korea

Leaf blight and bulb rot symptoms were observed on narcissus plants grown in Yongin, Cheongwon and Namhae areas in Korea during disease survey from 1999 to 2002. A total of 15 isolates of Botrytis sp. were obtained from the infected plant parts of narcissus. All the isolates were identified as Botrytis narcissicola based on their morphological and cultural characteristics. Three isolates of B. ...

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...

Oxidation of alcohols by Botrytis cinerea.

Crude cell-free preparations of Botrytis cinerea were found to oxidize straight-chain primary alcohols (except methanol), aromatic primary alcohols, and unsaturated primary alcohols. The resulting products were the corresponding aldehydes and an equal molar quantity of hydrogen peroxide.
