"Isozyme variation in ""helminthosporium-type"" species pathogenic on maize"
Abstract
dc:descriptionThe population structure of three species of fungi pathogenic on Zea mays L.; Cochliobolus carbonum, C. heterostrophus, and Septosphaeria turcica were studied using isozyme analysis. Forty isolates of S. turcica were evaluated using nineteen enzyme stains. Polymorphisms were identified with aspartate aminotransferase (EC 2.6.1.1), fumarase (EC 4.2.1.2), glucose-6-phosphate dehydrogenase (EC 1.1.1.49), and mannose-6-phosphate isomerase (EC 5.3.1.8). Associated electrophoretic and virulence phenotypes were found, indicating that populations exist in S. turcica as asexually propagated clonal groups. Use of the UPGMA method to calculate overall similarity between isolates found that isolates of race 1 were more similar to race 2 than isolates of race 3.
