Reconstruction of evolutionary history of several plant families using bioinformatics as a framework
for comparative studies
Bioinformatics is getting vital in the genomic era with the advance of sequencing techniques leading to large amounts of
datasets generated around the world. Similarly is the emerging importance of the comparative studies, instead of focusing
on understanding one particular model species in previous days, to find the mechanisms basal and universal to most of the
species as well as the ones specified to a few organisms. However, a well-resolved and robust phylogeny is required for many of
the comparative studies to make assumptions as well as possible. Thus, we focus on resolving the phylogeny of angiosperms,
hoping to provide a framework for comparative studies in plants. Using large numbers of transcriptomic datasets, we selected
hundreds of low-copy or single-copy nuclear genes to reconstruct the phylogeny of several angiosperm families such as
Asteraceae, Rosaceae and Brassicaceae. In these studies, we first provide a solid relationship among members of these families by
using different approaches to confirm the results, and then reconstruct the history of morphological characters or gene/genome
duplications based on the model phylogeny. We have found repeated and nested whole-genome duplications in Asteraceae, and
also reveal the evolutionary history of fruit type in Rosaceae . Furthermore, we especially focus on and anticipate providing a
solid framework and sufficient information for Brassicaceae to be used as a model family in plant biology.
