Genetic diversity and structure of the critically endangered a crop wild relative of jackfruit ().

Limestone karsts of Southeast Asia can harbor high levels of endemism, but are highly fragmented, increasingly threatened, and their biodiversity is often poorly studied. This is true of the Padawan Limestone Area of Sarawak, Malaysia, home to the endemic the closest known wild relative of two important and underutilized fruit tree crops, jackfruit () and cempedak (). Identifying and conserving crop wild relatives is critical for the conservation of crop genetic diversity and breeding.
