Arameiosis Lab

In flowering plants, meiosis generates spores with a halved ploidy, which ensures fertilization and maintains genome stability over generations. Meanwhile, meiotic recombination during prophase I leads to exchange of DNA fragments between homologous chromosomes through formation of crossovers, which create genetic diversity and facilitate evolution.

We have special interests to study the following aspects or questions:

1. The genetic mechanisms controlling meiosis in plants;

2. How does meiosis in plants respond to environmental stresses, especially extreme temperatures?

3. How does tapetum, the somatic cell layer surrounding meiocytes or developing pollen grains in the anthers, involve in regulation of meiosis?

We expect that our studies could contribute to the understanding of plant meiosis and its application on breeding.
