Abstract/Contents: | "Four varieties of Rhizoctonia circinata; var. agrostis, var. circinata, var. oryzae and var. zeae, are the causal agents of turfgrass diseases during warm seasons. As their symptoms are quite similar, it is difficult to distinguish among these four varieties. Conventional identification technique based on the cultural morphology of the isolated pathogen is laborious and time-consuming. For rapid detection of each variety of R. circinata, specific primers were designed from the sequence data of internal transcribed spacers of ribosomal DNA (rDNA-ITS region). The primers were Agro-1F for R. c. var. agrostis, Cir-2F for R. c. var. circinata, Ory-1F for R. c. var. oryzae and Zea- 2F for R. c. var. zeae. Each primer pair of Agro-1F/ITS 4, Cir-1F/ITS 4, Ory- 1F/ITS 4 and Zea-2F/ITS 4 could respectively produce a single PCR product from pure fungal DNA for each variety of R. circinata. When the primers were tested on other fungal pathogens of turfgrass, they showed no PCR products. The primer pairs of Agro-1F/ITS 4, Cir-2F/ITS 4, Ory-1F/ITS 4 and Zea-2F/ITS 4 are specific and useful for the rapid detection of respective R. circinata varieties." |
