In southern Africa dying Boabs have been reported and subsequent surveying of these trees has indicated the presence of the fungal pathogen Lasiodiplodia which may be the cause of the decline. Due to the close genetic relationship of the African and Australian Boabs and the fact that these two continents share are large amount of floral families, they may subsequently also share the pathogens of many of these plants. The surveying of the otherwise healthy Australian Boab and surrounding tree species deemed a prudent course of action.
In this study Boabs were surveyed in 25 sites in the Kimberley region and material was also taken from surrounding tree species at 3 sites. Endophytic fungi that were isolated from these samples were identified using both molecular and morphological data and seven new species were described (2). The pathogenicity of identified species to Boabs was determined. This is the first study to identify endophytes of the Adansonia and to conduct pathogenicity trials on these trees.
