Components of Resistance to an Indian Source of Cercospora Arachidicola in Selected Peanut Lines1

Effects of Temperature and Wetness Duration on Infection of Peanut Cultivars by Cercospora arachidicola.

ABSTRACT The effects of temperature and duration of wetness (relative humidity >/=95%) on infection of three peanut cultivars by Cercospora arachidicola were determined under controlled conditions. Plants of the Spanish cv. Spanco and the runner cvs. Florunner and Okrun were exposed to constant temperatures of 18 to 30 degrees C during 12-h periods of wetness each day that totaled 12 to 84 h fo...

Ethylene Production and Leaflet Abscission of Three Peanut Genotypes Infected with Cercospora arachidicola Hori.

Ethylene can induce abscission of leaves and other plant organs. Increased ethylene production by plant tissues can occur after invasion by microorganisms. The fungus Cercospora arachidicola Hori, attacks peanut leaflets and causes defoliation. Our objective was to determine if ethylene was involved in this defoliation. Leaves of three peanut, Arachis sp., genotypes were inoculated with C. arac...

Genetics of Dothistromin Biosynthesis in the Peanut Pathogen Passalora arachidicola

The peanut leaf spot pathogen Passalora arachidicola (Mycosphaerella arachidis) is known to produce dothistromin, a mycotoxin related to aflatoxin. This is a feature shared with the pine needle pathogen Dothistroma septosporum (Mycosphaerella pini). Dothistromin biosynthesis in D. septosporum commences at an unusually early stage of growth in culture compared to most other fungal secondary meta...
