Simulating diversity hotspots of wild relatives of aquatic vegetable crops in China
Aquatic vegetable crops are a unique group of domesticated crops from the farming civilization of the Yangtze River Basin,and their wild relatives are valuable genetic resources for breeding and variety improvement.This study utilized online database information from the iPlant and the Chinese Virtual Herbarium to obtain the geographical distribution data of 36 wild relatives of 10 aquatic vegetable crops.We used the maximum entropy model(MaxEnt)to construct an ecological niche model in conjunction with climatic factor data to predict future changes in species distributions.The results revealed that diversity hotspots for these wild relatives are concentrated in the Dongting Lake and Poyang Lake basins,aligning with the origin of the Yangtze River Basin farming civilization,indicating a historical proximity between the civilization and its plant resources.Under the climate scenario of future warming,the suitable distribution hotspots of wild relatives of aquatic vegetable crops may expand further,and the centers of diversity hotspots may migrate to high latitudes.This scenario could favor the maintenance and enhancement of wild relatives'diversity,providing a theoretical basis for their conservation.
