Cultural characteristics, morphology, and variation within Claviceps africana and C. sorghi from India.
Sorghum ergot in India is caused by Claviceps africana and C. sorghi. The distributions of these two species in India is not known. Eighty-nine sorghum ergot isolates were cultured from young sphacelia obtained from male sterile sorghum plants artificially inoculated using inoculum collected in the field. Based on cultural characteristics, the isolates were separated into two groups which diffe...
متن کاملInoculated Host Range and Effect of Host on Morphology and Size of Macroconidia Produced by Claviceps africana and Claviceps sorghi
Twenty graminaceous plant species were evaluated for their susceptibility to the two sorghum ergot pathogens Claviceps sorghi and Claviceps africana. Five species viz., Sorghum arundinaceum, Sorghum halepense, Sorghum versicolor, Sorghum virgatum and Pennisetum glaucum were found to become infected by both pathogens via inoculation with 10 conidia/ml. Species which did not become infected under...
متن کاملAnalysis of Claviceps africana and C. sorghi from India using AFLPs, EF-1alpha gene intron 4, and beta-tubulin gene intron 3.
Isolates of Claviceps causing ergot on sorghum in India were analysed by AFLP analysis, and by analysis of DNA sequences of the EF-1alpha gene intron 4 and beta-tubulin gene intron 3 region. Of 89 isolates assayed from six states in India, four were determined to be C. sorghi, and the rest C. africana. A relatively low level of genetic diversity was observed within the Indian C. africana popula...
متن کاملSugary disease or Asian ergot of sorghum - Claviceps sorghi
Claviceps sorghi is a pathogen of Sorghum bicolor found only in India and Southeast Asia. The more widespread C. africana is predominant even in India; C. sorghi appears to be marginalized in its restricted range. A significant difference in invasiveness is the relative production of inoculum that spreads plant-to-plant. Claviceps sorghi produces few to no secondary conidia from macroconidia on...
متن کاملInhibition of germination and sporulation of Claviceps africana from honeydew encrusted sorghum with seed treatment fungicides
The inhibitory e!ects of six fungicides on macrospore germination and production of secondary conidia of Claviceps africana were studied. E!ects of these fungicides on germination of sorghum seed also were determined. Panicles from male-sterile sorghums with honeydew exudate were harvested from the USDA-ARS Research Farm, Isabela, Puerto Rico in the Spring of 1997. Honeydew exudate-infested pan...
