Phylogenetic diversity of and fumonisin gene cluster distribution within Fusarium isolates from wild banana in China

Banana fruit is one of the most important crops and is currently the second most important fruit produced all over the world. Several Fusarium species have been identified as important pre- and post-harvest pathogens of cultivated banana. However, there are no studies that have been conducted to identify Fusarium contaminants on wild banana. The first objective of this work was to study the phylogenetic and genetic diversity of Fusarium isolates from the F. fujikuroi species complex contaminating fruits of wild banana plants growing in two southern Chinese Provinces, Hainan and Yunnan. The second objective was to study the distribution and configuration of the fumonisin gene cluster within these Fusarium species.
