Oligosaccharides are important elicitors that can induce resistance of plants against pathogens. In this review, we have summarized the kinds of oligosaccharides and the mechanism of plant induced resistance by oligosaccharides. Oligosaccharides could bind to the receptor on plasma membrane, and excite the burst out of active oxygen species （AOS） in plat cell, increase intrcellular NO and H2O2. oligosaccharides could induce expression of related resistance gene, increase activity of related resistance enzyme such as PAL, chitinase and β-1,3-glucanase. Oligosaccharides could induce the productionn of Phytoalexin.

Viruses from several families may cause epizootics of insects in natron, they are key factors that adjust the density of insect populations. As there are several advantages for insect viruses as bioinsecticides, such as safe for human being and environment, no resistance for insect to virus, and control pest insects for long term, etc. , they are widely and deeply studied around tile world. Here we review recent progresses in the development of wild-type virus as insecticides, the development and bio-safety assessment of genetically modified baculoviruses and new techniques of application of insect viruses in China.

To solve the problems such as the redundant, overlapped, personnel scattered, vague aimed of public welfare and low efficient existing among the scientific research institutions for public welfare （SRIPW） in China, a reform launched in 2001 is expected to make two innovations： separate the business oriented sector from the SRIPW and turn the SRIPW pattern into the nonprofit organization （NPO） pattern. However, the reform practice shows it wouldn＇t be achieved in the short term. This paper analyses the transitional pattern ＂ one institution two systems＂ which occurs in the reform process, evaluates the reform performance of SRIPW and points out the necessity to stabilize the ＂one institution two systems＂ and develop the quasi-NPO at present.
