Title: Recursive polyploidizations and related biological consequences during the
evolution of land plants (with grasses as models)
Abstract: The evolution of land plants has featured recursive polyploidizations,
affecting nearly main plant lineages and possibly contributing to their fast divergence
and expansion on the land surface of the earth. Accumulated researches report their
contributions to genome repatterning, illegitimate recombination (resulted in gene
conversion and crossing-over), innovation of biological pathways, and adaption to
environmental stresses.
Xiyin Wang is currently the Professor and the Dean, College of Life Sciences, Hebei
United University; and Visiting Research Professor, University of Georgia. He
obtained his PHD (Molecular Biology and Bioinformatics) from Beijing University in
2005. Previously, he obtained his B.S. (Mathematics) from Jilin University, 1995. He
has been involved in many plant genome sequencing efforts as one of key members,
by leading comparative genomics explorations, in sorghum, papaya, tomato,
*Brassica rapa* (Chinese cabbage), *Brassica oleracea*, and cotton; and has made
diverse contributions in diverse directions:
