Conidia were falcate, hyaline, unicellular and aseptate, formed in acervuli, with variable dimensions. truncatum sequences from other regions around the world, while others were related to alternative hosts. Intraspecific genetic diversity revealed 27 distinct haplotypes in 51 fungal isolates some of which were identical to C. All isolates clustered only with Colletotrichum truncatum species in three well-separated clusters. Methods and Resultsīayesian phylogenetic inference of GAPDH, HIS3 and ITS- 5.8S rDNA sequences, the morphologies of colony and conidia, and inoculation tests on seeds and seedlings were performed. Colletotrichum isolates from soybean plants with anthracnose symptoms were studied from different regions and time periods in Brazil using molecular, morphological and pathogenic analyses. ![]() ![]() ![]() Fungal diseases are among the main factors limiting high yields of soybean crop.
