Research Fields
  • Evolution, Phylogenetics and comparative genomics of seed plants

Research Directions

  • 1.Comparative chloroplast genomics of conifers.
    Conifers are of immense ecological and economic value, their chloroplast bioengineering remains undeveloped. Understanding their chloroplast genomic organizations shall facilitate their bioengineering. We are exploring the diversity and structural evolution of chloroplast genomes (cpDNA) of conifers. Using next generation sequencing and comparative genomics approaches, we aim to unravel the evolution of highly variable cpDNA structures in conifers. In addition, study on the evolutionary process for loss of a large inverted repeat and adaption of frequent rearrangements is carrying out in the conifer cpDNAs.
  • 2.Evolution of mitochondrial genomes in gymnosperms.
    Presently, the complete mitochondrial genomes (mtDNAs) of gymnosperms are limitedly known for a cycad, Cycas taitungensis, among the 1,000 species of gymnosperms. Gymnosperms are considered as ‘‘inextricably related to the origins and early divergence of seed plants’’(Chaw et al. 1997). The evolution of mtDNAs is more complex than that of cpDNAs because mtDNAs have horizontal gene transfer, uptake of chloroplast and nuclear DNA sequences, extreme size and rate variations, rapid gene rearrangements, more trans-splicing exons, and RNA editing sites. To expand our understanding of mtDNA organization and evolution, we have been sequencing four representative taxa from each of the four major lineages, ginkgo, gnetophytes, conifers I (Pinaceae), and conifers II.
