Changes in Cell Membrane Permeability in Sunflower Hypocotyls Infected with Sclerotinia sclerotiorum.
Influx and efflux of water and urea and electrolyte leakage are less for sunflower (Helianthus annuus) hypocotyl sections above lesions caused by Sclerotinia sclerotiorum than for those from healthy plants. Urea uptake by sections above lesions is reduced (celery, squash, and tomato) or unchanged (bean) in other hosts after Sclerotinia infection. Efflux of urea from sunflower hypocotyls is biph...
متن کاملMethods of determining the reaction of sunflower genotypes to terminal bud attack by Sclerotinia sclerotiorum ( Lib ) De Bary
as a basis for comparison of the different test methods, since it has been shown that genotype ranking according to reaction to natural attack is stable. Two tests gave results significantly correlated with those of natural attack. A test measuring mycelium extension along the young stem from an explant placed on the terminal bud gave a correlation of r = 0.554 (n = 20). An infection by ascospo...
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 کاملCharacterization of Sclerotinia sclerotiorum Isolated from Paprika
A fungal isolate collected from infected paprika (Capsicum annuum var. grossum) was characterized as Sclerotinia sclerotiorum based on its ability of sclerotium formation, physiological and molecular properties. When the isolate was grown on potato dextrose agar, oatmeal agar, and malt extract agar, it grew most well on PDA. Optimal temperature and pH for its growth were 25℃ and pH 7, respectiv...
متن کاملAnalyses of QTL associated with resistance to Sclerotinia sclerotiorum and Diaporthe helianthi in sunflower (Helianthus annuus L.) using molecular markers
Most traits exhibit continuous variation resulting from the action of multiple genes modified by the environment. Quantitative trait loci (QTL) analysis consists in determining the location and number of genes that condition such quantitative traits and estimating the magnitude of individual gene effect by the use of analytical methods and detailed linkage map. Sclerotinia sclerotiorum and Diap...
