Botryosphaeria dothidea endophytic in Eucalyptus grandis and Eucalyptus nitens in South Africa

Botryosphaeria dothidea is well recognised as a serious pathogen of various woody plants, including species of Eucalyptus. In South Africa, the fungus is associated with die-back and canker diseases of various Eucalyptus species. In the present study, B. dothidea was found to be the dominant taxon o...

Description
Summary:Botryosphaeria dothidea is well recognised as a serious pathogen of various woody plants, including species of Eucalyptus. In South Africa, the fungus is associated with die-back and canker diseases of various Eucalyptus species. In the present study, B. dothidea was found to be the dominant taxon occurring as a latent symptomless endophyte in healthy leaves of E. grandis and E. nitens from two distinct climatic and geographical locations in South Africa. This fungus occurred consistently in trees and apparently infects all leaf parts. Disease symptoms associated with B. dothidea in South Africa may thus result from the manifestation of previous latent infections after the onset of stress.
