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.
