Abstract:
Fruits are the reproductive organs of angiosperms and greatly influence the pattern, effectivity, and distance of seed dispersal. Fruit type diversity is partly responsible for the ecological variation among plant taxa and impacts the diversification rates and patterns of flowering plants. This review expounds several key pathways and the evolutionary mechanism of fruit type diversity, discusses the potential factors affecting the evolution of fruit types, and illustrates the evolutionary routes and patterns of fruit types to provide insight into angiosperm fruit diversity and evolution.
