I. Orchid Comparative Genomics

     Constituting approximately 10% of flowering plant species, orchids display unique flower morphologies, possess an extraordinary diversity in lifestyle, and have successfully colonized almost every habitat on Earth. Comparison of orchid genomes could improve our understanding of their origins and evolution. We are interested in exploring the orchid genomes with genomics tools and try to uncover the evolution mystery of orchid by comparative genomics.

II. Orchid Floral Evolutionary Development

     The diversity and specialization in orchid floral morphology have fascinated botanists and collectors for centuries. The complex flower organization of orchids offers an opportunity to discover new variant genes and different levels of complexity in the morphogenesis of flowers. We are interested in molecular development and evolutionary trajectory of orchid floral morphogenesis.

III. Orchid secondary metabolome

     The use of orchids in herbal medicine has a very long history. Totally 365 plants, including several orchids are listed in the earliest known Shen Nung Pen Tsao Ching. It provides an important direction for people to understanding how to use orchids as herbal medicine. To discover the medical value of novel components in orchid plants is potential for investment.
