Abstract : Mango (Mangifera indica) malformation caused by Fusarium mangiferae has been reported in many mango-growing regions of the world. The disease was also observed in Yunnan and Sichuan provinces of China. To identify the pathogen, samples of malformed and healthy mango seedlings were collected from affected plants. Based on morphology, the isolate was identified as F. mangiferae. Pathogenicity tests were conducted and reisolations from the induced malformed shoots yielded the same fungus, and no fungal growth was observed from the control plants. To confirm the identity of the causal fungus, the gene encoding translation elongation factor 1 alpha was amplified and sequenced. The sequence (GenBank Accession No. HM068871) was 99.68% similar to sequences of FD_011667 in the Fusarium ID database. This is thought to be the first report of F. mangiferae causing mango malformation in China.
