Research

A "BIG genus" in plants refers to a genus containing more than 500 species, most of which are found in the tropics. The high diversity of these plants in a highly competitive tropical environment must be due to special mechanisms of speciation. My study, based on the plant systematics of highly diverse taxa such as Elatostema and Begonia, mainly uses molecular phylogenetics, reproductive biology, genomics, and next-generation techniques to investigate a mystery that has long puzzled Darwin - why do plants produce such high diversity so rapidly?

Main research directions:
(1) Plant systematics and phylogenetics
(2) Population genomics in parasitic plants
(3) Evolution of plant sexual system and mechanisms of apomixis
(4) Plant speciation mechanisms
(5) Structural analysis and evolution of plastome and mitochondrion
