dc.description.abstractThe family Ceratocystidaceae includes economically important plant pathogens that vary in host preference and lifestyle. These fungi are believed to attract insect vectors, for their dispersal through their floral and fruity scents. This study aimed to identify the volatiles produced by a subset of fungi within the Ceratocystidaceae using gas chromatography coupled with mass spectrometry. The primary volatiles produced by most genera in the family were fusel alcohols and fusel acetates, but their emission rates differed significantly between genera and isolates from a single species. Ceratocystis albifundus collected from Protea cynaroides produced higher levels of fusel acetates compared to isolates from Terminalia sericea. In addition, significant differences in volatile biosynthesis were observed between isolates grown under different temperatures. Results of this study demonstrate that Ceratocystidaceae exhibit varied volatile profiles, but further research is needed to understand the ecological and physiological mechanisms underlying this plasticity.
