Hyparrhenia rufa

Recently, a Claviceps sp. on Hyparrhenia rufa was found in southern Africa (Frederickson and Pazoutova, unpublished) whose conidia were very similar to C. africana, and its sclerotia were of the same shape as seeds of the host plant. RAPD patterns showed that it is indeed another population of C. africana, but more different than any of the sorghum isolates, which may be the beginning of speciation based on host adaptation. Although Hyparrhenia plants were neighbors of a sorghum field, no RAPD pattern similar to that of Hyparrhenia population was found among sorghum isolates.
