| The identification of Diaporthe (anamorph Phomopsis) species associated with stem canker of sunflower (Helianthus annuus) in Australia was studied using morphology, DNA sequence analysis and pathology. Phylogenetic analysis revealed three clades that did not correspond with known taxa, and these are believed to represent novel species. Diaporthe gulyae sp. nov. is described for isolates that caused a severe stem canker, specifically pale brown to dark brown, irregularly shaped lesions centred at the stem nodes with pith deterioration and midstem lodging. This pathogenicity of D. gulyae was confirmed by satisfying Koch’s Postulates. These symptoms are almost identical to those of sunflower stem canker caused by D. helianthi that can cause yield reductions... |
