简介
Anthracnose caused by Elsinoë ampelina is one of the most important table grape diseases in humid regions in Brazil and Australia. The objective of this study was to characterize E. ampelina isolates from Brazil and Australia by means of phylogenetic analyses, morphological features and pathogenicity tests. Phylogenetic relationships among 35 isolates were determined based on a data set of internal transcribed spacer (ITS), histone H3 (HIS3) and elongation factor 1‐α (TEF) sequences. In phylogenetic tree analyses, using a combined ITS and TEF sequence alignment, all E. ampelina isolates were clustered together in a single well‐supported clade. In contrast to the absence of genetic variability within ITS and TEF sequences, HIS3 sequences showed 54 polymorphic sites. The haplotype network generated from HIS3 data set showed four distinct haplotypes. EA1 was the predominant haplotype including 29 …
