Biocontrol of seedborne Botrytis cinerea in chickpea with Gliocladium roseum

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

Nematicidal epipolysulfanyldioxopiperazines from Gliocladium roseum.

Five new verticillin-type epipolysulfanyldioxopiperazines, gliocladine A (1), B (2), C (3), D (4), and E (5), were isolated from wheat solid-substrate fermentation of Gliocladium roseum 1A, along with four known compounds, verticillin A (6), 11'-deoxyverticillin A (7), Sch52900 (8), and Sch52901 (9). Their structures were elucidated by extensive 1D and 2D NMR studies, MS, and chemical transform...

The Biocontrol Efficacy of Streptomyces pratensis LMM15 on Botrytis cinerea in Tomato

LMM15, an actinomycete with broad spectrum antifungal activity, was isolated from a diseased tomato leaf using the baiting technique. A phylogenetic tree analysis based on similarity percentage of 16S rDNA sequences showed that the bacterium was 97.0% affiliated with the species Streptomyces pratensis. This strain was therefore coded as S. pratensis LMM15. The ferment filtrate of LMM15 had abil...

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...

ISOLATION AND SELECTION OF EPIPHYTIC YEAST FOR BIOCONTROL OF Botrytis cinerea PERS. ON TABLE GRAPES

Botrytis cinerea Pers., the causal agent of gray mold, infects more than 200 plant species. This pathogen has traditionally been controlled by fungicides. However, with the increasing demand for pesticide-free foods new control strategies are needed. The objective of this study was to isolate and select grapevine (Vitis vinifera L.) epiphytic yeasts for the biocontrol of B. cinerea in table gra...
