متن کاملIn Vitro Toxin Production by Fusarium solani f. sp. piperis
Fusarium solani f. sp. piperis (teleomorph: Nectria haematococca f. sp. piperis), causal agent of root rot and stem blight on black pepper (Piper nigrum), produces secondary metabolites with toxigenic properties, capable of inducing vein discoloration in detached leaves and wilting in transpiring microcuttings. Production of F. solani f. sp. piperis (Fsp) toxic metabolites reached a peak after ...
متن کاملGenetic Analysis of Dodine
HERE has been a small amount of published information on the genetics of the heterothallic ascomycete causing root and fruit rot of cucurbits. In these publications the fungus has been referred to as Hypomyces solani f. cucurbitae. However, according to DINGLEY (1961), this organism belong to the species Nectria haenzatococca and should be called N . haematococca var. cucurbitae. Genetic knowle...
متن کاملReview. Meiotic drive and sex determination: molecular and cytological mechanisms of sex ratio adjustment in birds.
Differences in relative fitness of male and female offspring across ecological and social environments should favour the evolution of sex-determining mechanisms that enable adjustment of brood sex ratio to the context of breeding. Despite the expectation that genetic sex determination should not produce consistent bias in primary sex ratios, extensive and adaptive modifications of offspring sex...
