This invention relates to several plasmids which are useful for genetically transforming plant cells. A first plasmid, such as pMON120, contains a T-DNA border, one or more marker genes, a unique cleavage site, and a region of Ti plasmid homology. A gene which is expressed in plant cells may be inserted into this plasmid to obtain a derivative plasmid, such as pMON128 which expresses neomycin phosphotransferase in plant cells. The derivative plasmid is inserted into a suitable microorganism, such as A. tumefaciens which contains a Ti plasmid. The inserted plasmids recombine with Ti plasmids to form co-integrate plasmids. Only a single crossover event is required to create the desired co-integrate plasmid. A. tumefaciens cells with co-integrate plasmids are selected and co-cultured with plant cells. The co-integrate Ti plasmids enter the plant cells and insert a segment of T-DNA which does not contain tumorigenic genes into the plant genome. The transformed plant cell(s) may be regenerated into a morphologically normal plant which will pass the inserted gene(s) to its descendants.

The appraisal method of glyphobacterium is a method of identification between bacteria species.It is a bacterial testing technology.At present, there are many tests used for identification of glyphobacterium species, complex steps, difficult to find, and less identification bacteria.The present invention uses 15 tests: oxidase, plasma coagulatases, neonomycin, chitosaccharides, VP, mananose, cotton sugar, eloarose, urea, natin, sucroseAlcohol has established the "Bacteria Identification Form", which overcomes the lack of previous methods.The specific technical solution is: (1) First test with oxidase, plasma coagulant, and texycin to determine the level of unknown staphylococci.(2) Use the test of internal connection at the level of the affiliation.(3) In contrast to the test results with the appraisal table, you can find the bacteria that you want to identify.The characteristics of the present invention: The operation is easy, the steps are clear, and the results are easy to check.Can be appraised for 30 species of bacteria.
