Abstract

Fusarium is a large and diverse genus of fungi that includes many economically important plant pathogens, which cause wilts, blights, root and stalk rots and cankers in a wide variety of crops. Multiple pathogenic and endophytic species of Fusarium have been isolated from sorghum crops in Australia, the taxonomic position of many of which remains unknown. The Fusarium spp. associated symptomatic and asymptomatic sorghum stalk in Queensland was investigated to elucidate the taxonomy of species associated with with symptomatic infection and those which may be investigated further to determine potential benefit to the soil microbiome. Using molecular techniques, three novel Fusarium spp. were identified and described, and several species were identified that have been previously reported in Australia. These included F. andiyazi, F. thapsinum, F. nygamai, F. verticillioides and F. proliferatum. Several Fusarium spp. were reported for the first time in Australian sorghum, including F. atrovinosum, F. vasinfectum and F. clavatum in sorghum and F. nanum and F. tardicrescens in Australia. No significant difference was found in the number or variety of species isolated from either symptomatic or asymptomatic sorghum. Pathogenicity studies and co-infection trials are recommended to clarify pathogenicity of the species isolated.
