Research Interests
  1. Morphogenesis and developmental genetics of flower shape, anisocotyly and bulbils
  2. Phylogeography of East Asia relic gymnosperm and endemic angiosperm species
  3. Molecular phylogenetics, phylogeography and polyploidization of ferns
Lab Introduction: Plant evo-devo Lab

My research focuses on: (1) understanding the evolutionary developmental genetics of flower shape, anisocotyly and bulbil development in respects to floral symmetry and ectopic meristem formation; (2) resolve the phylogeographic patterns and speciations of East Asia endemic species, especially relic gymnosperms, disjunctly distributed ferns and flowering plants, by integrating evidence from morphology, cytology, breeding and molecules.

My laboratory has taken an evo-devo approach to study the evolution of floral bilateral symmetry in Gloxinia (Sinningia speciosa), the evolution of anisocotyly and anisophyly in Streptocarpus rexii and other Gesneriaceae species, and the development of bulbils inflorescence in Titanotrichum oldhamii. The strategies include using fluorescence cytological stains to identify meristem positions, hormone treatments on cotyledon development, real-time PCR and in-situ hybridizations to examine candidate genes’ expression patterns and artificial crossings for genetic analysis. I developed a transformation protocol in S. speciosa allowing functional analysis of these developmental genes. We aim to elaborate Gesneriaceae species as a model to gain insight into the evolution of body plans and various life history traits that exemplify vascular plants.

I also use an explicit comparative phylogeography framework to examine evolutionary, ecological and spatial processes have shaped the present day distribution and population structure of East Asia relic and endemic species. I am interested in the application of genetic markers and DNA analysis, such as chloroplast and nuclear barcoding markers, genome-wide AFLP and microsatellite analysis, to answer questions regarding population history, population genetic structure, hybridizations, polyploidization, adaptation and for conservation suggestions. Analysis of molecular data on these representative ferns, gymnosperm and angiosperm species should provide us a working hypothesis that explain high endemism and the great biodiversity of Taiwan flora.
