"Sorghum ergot, initially restricted to Asia and Africa, was recently found in the Americas and\r\nAustralia. Three species causing the disease have been reported: Claviceps sorghi in India, C.\r\nsorghicola in Japan, and C. africana in all ergot-positive countries. The objective of our study\r\nwas to study the intraspecific variation in C. africana isolates in the Americas, Africa, India,\r\nand Australia. We confirmed C. africana, C. sorghi, and C. sorghicola as different species using\r\ndifferences in nucleotide sequences of internal transcribed spacer 1 and 5.8S rDNA regions.\r\nSequences of this region obtained from the representative American, Indian, and Australian\r\nisolates of C. africana were identical. In addition, random amplified polymorphic DNA (RAPD)\r\nbanding patterns of sorghum ergot pathogen isolates from the United States, Mexico, Puerto\r\nRico, Bolivia, Australia, and India were evaluated with nearly 100 primers. A total of 65 primers\r\ngave identical patterns for all isolates, which confirmed that all were C. africana. The identity\r\nof RAPD pattern and rDNA sequence of Indian isolates with those of C. africana confirmed\r\nthat the species is now present in India. Only 20 primers gave small pattern differences and 7 of\r\nthem were used for routine testing. All of the American isolates were identical and three isolates\r\nof the same type were also found in South Africa, suggesting Africa as the origin of the\r\ninvasion clone in the Americas. Australian and Indian isolates were distinguishable by a single\r\nband difference; therefore, migration from the Asian region to Australia is suspected. Another\r\ndistinct group was found in Africa. Cluster analysis of the informative bands revealed that the\r\nAmerican and African group are on the same moderately (69%) supported clade. Isolates from\r\nAustralia and India belonged to another clade."^^ . "2000" . . "84" . "4" . . "American Phytopathological Society"^^ . . . "Plant Disease"^^ . . .
