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.
Necrotrophic fungi are unable to occupy living plant cells. How such pathogens survive first contact with living host tissue and initiate infection is therefore unclear. Here, we show that the necrotrophic grey mold fungus Botrytis cinerea undergoes massive apoptotic-like programmed cell death (PCD) following germination on the host plant. Manipulation of an anti-apoptotic gene BcBIR1 modified ...
Fungal endophytes are important in plant ecology and common in plants. We attempted to test cointroduction and host-jumping hypotheses on a community basis by comparing endophytes isolated from invasive spotted knapweed (Centaurea stoebe, Asteraceae) in its native and invaded ranges. Of 92 combined, sequence-based haplotypes representing eight classes of Fungi, 78 occurred in only one of the tw...
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. ...
In our earlier investigation, a fungal isolate Penicillium citrinum VFI-51 and its secondary metabolite was reported to have antagonistic potential against Botrytis cinerea, the causative agent of Botrytis gray mold disease in chickpea. In the present investigation, P. citrinum VFI-51 was further evaluated for its antagonistic potential against Macrophomina phaseolina, the causative agent of ch...
Plant-microbial interactive relations with respect to determine mycoflora of the Sorbus domestica L.--fruits, crust, leaves and pollen were studied in 2 Slovak regions. On the fruit samples the genera Alternaria, Botrytis, Cladosporium, Mucor and Penicillium occurred, on the leaves the genera Alternaria, Cladosporium and Penicillium prevailed and on crust the genera Alternaria, Cladosporium, Pe...
T he p reny la ted isoflavone, 2 ,3-dehydrokievitone [5 ,7 ,2 ',4 '-tetrahydroxy-8-(3 ,3-dim ethylally l)isoflavone, 1], was m etabolized by both Aspergillus flavus and Botrytis cinerea to yield the sam e th ree com pounds, a dihydrofurano-isoflavone (D K -M 1, 2), a d ihydropyrano-isoflavone (D K M 2, 3), and a glycol (D K -M 3, 4). A lthough structure 3 has previously been assigned to lunaton...
Botrytis cinerea is a ubiquitous necrotrophic fungal pathogen that infects over 200 different plant species. We have analyzed 17 Arabidopsis ecotypes for natural variations in their susceptibility to B. cinerea, and found compatible and incompatible Arabidopsis–Botrytis interactions. We determined that Arabidopsis ecotype Ler is resistant to 5 B. cinerea isolates used in this study. To further ...
