Fusarium fujikuroi causing fusariosis of pineapple in peninsular Malaysia

摘要

Fusariosis symptoms were detected on pineapple fruits and leaves in several states in Peninsular Malaysia. Eight Fusarium fujikuroi isolates were isolated and identified using a partial Translation Elongation Factor -1α (TEF) and β-tubulin sequences. The isolates showed 98–100?% similarity with F. fujikuroi NRRL43610. Phylogenetic analysis of the combined TEF and β-tubulin sequences showed that the eight isolates clustered with F. fujikuroi from rice. Koch’s postulates were fulfilled on pineapple fruits and leaves confirming pathogenicity of the F. fujikuroi isolates.
