Comparative survival of Sclerotia of Sclerotinia minor and S. sclerotiorum.
Survival of sclerotia of Sclerotinia minor and S. sclerotiorum was compared in irrigated fields during the summer in two major lettuce production areas in California. More than 50% sclerotia of S. sclerotiorum compared with 4 and 35% of S. minor remained viable after 24 weeks of burial at 15 and 5 cm depths, respectively, in the San Joaquin Valley while >80% of sclerotia survived in the Salinas...
متن کاملAntagonism of Aspergillus Terreus to Sclerotinia Sclerotiorum
An Aspergillus terreus strain showed in vitro antagonistic activity against the plant pathogen Sclerotinia sclerotiorum (Lib.) de Bary. The interaction between A. terreus and sclerotia revealed that the mycoparasite sporulated abundantly on the sclerotial surface. Cell breakdown due to host cell wall disruption was observed in inner rind cells, by a scanning electron microscopy.
متن کاملComparative Transcriptomic Analysis of Virulence Factors in Leptosphaeria maculans during Compatible and Incompatible Interactions with Canola
Leptosphaeria maculans is a hemibiotrophic fungus that causes blackleg of canola (Brassica napus), one of the most devastating diseases of this crop. In the present study, transcriptome profiling of L. maculans was performed in an effort to understand and define the pathogenicity genes that govern both the biotrophic and the necrotrophic phase of the fungus, as well as those that separate a com...
متن کاملAscospore release and survival in Sclerotinia sclerotiorum.
The release and survival of ascospores of a UK Sclerotinia sclerotiorum isolate were studied. Apothecia placed in a spore clock apparatus with different lighting regimes at 15 degrees C released ascospores continuously with an increasing rate for the duration of experiments (72-84 h). Spore release was not confined to light or dark periods in alternating regimes and occurred in continuous dark ...
متن کاملSeasonal and Diurnal Patterns of Spore Dispersal by Leptosphaeria maculans
Canola (Brassica napus L. and B. rapa L.), is one of the major oilseed crops grown worldwide. With significant expansion of acreage sown to canola during the past two decades, concern about blackleg, the most serious disease of canola, has increased (3,4). Blackleg disease is caused by Leptosphaeria maculans (Desmaz.) Ces. & De Not. (anamorph: Phoma lingam (Tode:Fr.) Desmaz.). The pathogen can ...
