Microcycle Conidiation in Cercospora zeae-maydis.
ABSTRACT Conidia of Cercospora zeae-maydis are the primary inoculum causing gray leaf spot of maize. On nutrient-deficient substrates, but not on water on the leaf surface, conidia germinate and develop secondary conidia on conidiophores produced from germ tubes or conidial cells. A population of conidia increases its numbers more than twofold by 2 days on the surface of a water droplet and by ...
متن کاملPolyamines as modulators of microcycle conidiation in Aspergillus flavus.
Since polyamines (PAs) play a potential role in the regulation of growth and developmental processes in a wide variety of organisms, we have examined the influence of the PAs putrescine (Put) and spermidine (Spd) and the PA biosynthetic inhibitors alpha-difluoromethylornithine (DFMO), alpha-difluoromethylarginine (DFMA), methylglyoxal bis-(guanylhydrazone) (MGBG) and cyclohexylamine (CHA), sing...
متن کاملThe production of conidiophores and conidia by newly germinated conidia of Aspergillus niger (microcycle conidiation).
The ability of Aspergillus niger conidia to produce conidiophores after germination in shaken culture at 30" was stimulated by the inclusion of glutamate in the medium. Incubation of the conidia at 35" to 41" increased swelling of the conidia and also the proportion which produced conidiophores. Although conidio phore initiation was stimulated at temperatures between 35" and 41 ", maturation wa...
متن کاملCarbon Concentration and Carbon-to-Nitrogen Ratio Influence Submerged-Culture Conidiation by the Potential Bioherbicide Colletotrichum truncatum NRRL 13737.
We assessed the influence of various carbon concentrations and carbon-to-nitrogen (C:N) ratios on Colletotrichum truncatum NRRL 13737 conidium formation in submerged cultures grown in a basal salts medium containing various amounts of glucose and Casamino Acids. Under the nutritional conditions tested, the highest conidium concentrations were produced in media with carbon concentrations of 4.0 ...
متن کاملImprovement of Xylanase Production by Cochliobolus sativus in Submerged Culture
The xylanase production by a new Cochliobolus sativus Cs5 strain was improved under submerged fermentation. The xylanase was induced by xylan and repressed by glucose, sucrose, maltose, xylose, starch and cellulose. Highest enzyme production (98.25 IU/mL) was recorded when wheat straw (4 % by mass per volume) was used as a carbon source after 120 h of incubation. NaNO3 increased xylanase produc...
