Diversity of Botryosphaeria species on horticultural plants in Victoria and New South Wales

Abstract

To help understand the diversity of Botryosphaeria species found on horticultural crops in Victoria and New South Wales, 30 isolates were identified using rDNA ITS sequences and elongation factor 1 ? (EF-1 ?) gene sequences. Cultures had been isolated over the last 25 years and originated from 14 plant species, and about half were from grapevines, stone fruit and pome fruit. The most commonly encountered species were B. australis (8 times), B. obtusa (7 times), B. parva (7 times) and B. dothidea (5 times). Botryosphaeria ribis was identified only once and B. lutea twice. © Australasian Plant Pathology Society 2007.
