From 94 soil samples and 9 bark samples in these areas, 259 Myxobacteria strains were isolated and 140 strains of them were purified. These 259 Myxobacteria strains were primarily identified in genus or species level by their fruiting bodies, myxospores and vegetative cells on the base of Sergey's manual of determinative bacteriology and they belonged to 9 genera(Myxococcus, Corallococcm. Angiococcus. Archangium, Cystobacter. Stigmatella . Hapoangium. Nannocystis. Polyangium) of Myxococcales.

根据菌株的特征性子实体形态和其营养细胞、粘孢子形态，以《Bergey's manualof determinative bacteriology》第九版为依据，将分离纯化出的菌株初步鉴定到属，这259株粘细菌菌株经过初步的分类鉴定，分属于9个属，即粘球菌属139株、珊瑚球菌属20株、囊球菌属18株、原囊菌属21株、孢囊杆菌属5株、标桩菌属36株、单囊菌属9株、小囊菌属3株，和多囊菌属8株。

The open reading frame of Spinacia oleracea Betaine Aldehyde Dehydrogenase was retrieved from Spinacia oleracea and inserted into the Agrobacterium tumefaciens binary vector pBin438, which was driven by CaMV35S promoter, and produced the new binary vector pBSB. A. tumefaciens LBA4404 carrying this plasmid was used in genetic transformation of plants. Forty-five primary transgenic plants were detected by PCR and verified by the Southern blotting from 65 regenerated plants, of which 27 transgenic plants had only one copy of T-DNA.
