Laboratory of Plant Biotechnology
Laboratory of Plant Biotechnology is a one of
the key labs of Chinese Academy of Sciences, and also acts as the Plant
Biotechnology Subcenter of the Research Center for Biotechnology in China
under the International Science and Culture Center-World Laboratory and
the Beijing Program Office of Singapore-China Biotechnology Program. Our
laboratory is engaged in the basic and applied aspects of plant molecular
biology and plant biotechnology, especially those relevant to important
issues in China's agriculture.

The major research projects are related to:
1. structure of plant virus genomes and function
of the viral gene products;
2.development and application of genetically
modified plants resistant to viruses, phytopathogenic microbes, insects
and stress environments;
3.structure and expression regulation of plant
4.transgenic plants as bioreactors for production
of pharmaceutical proteins and vaccines.
Our recent achievements include:
1.genes coding for structural and non-structural
proteins of a number of plant viruses isolated in China have been sequenced.
In particular, the complete structure of the rice yellow stunt rhabdovirus
genome has been determined;
2.using the strategy of pathogen-derived resistance,
virus-resistant transgenic plants of various crops have been produced,
including tobacco, chili pepper, tomato, potato, oilseed rape and rice.
Tansgenic tobacco resistant to both TMV and CMV has been planted over 40,000
ha. and transgenic chili pepper and potato plants are being tested in fields.
3.insect-resistant poplar and cotton expressing
Bt toxins have been developed and the transgenic poplar trees are now in
large-scale field trials;
4.transgenic tobacco and potato resistant to
the bacterial wilt disease are obtained by expressing antimicrobial peptide
and T7 lysozyme;
5.salt-tolerant tobacco and maize have been produced
by using both gutD and mtlD genes of E.coli;
6.the structure and expression patterns of the
plant defense genes e.g.the rice glycine-rich protein gene and hsp70 gene,
have been analyzed.
The Laboratory has a staff of 15 researchers,
among them 4 are Professors and 2 Associate Professors. We provide Ph.D
and Master programs for students and positions for visiting scientists.
Currently there are 6 Ph.D students, 4 Master students and 10 Guest Investigators
in the laboratory.
