Abstract Check the type of bacteria that contaminated corn seed from seed collected corn from the major varieties of 58 samples from monitoring of contamination of Pantoea ananatis bacteria and characterization of bacterial species based on molecular, biochemical and morphology characteristics which separate seed from 1991.Total corn นธุ์ 34 I presented the letter of credit solutions paves the way for a breakdown by fuel type acute response reaction (HR) on plants and non-living plants; the test Koch postulation; Style your curve and biochemical confirmation inspection 16S-23S area; ITS new sequence and wokli properties are found at nearby tide with P. ananatis AI letter comparing fuel solutions. By its letter of credit solutions from corn to distinguish from P. ananatis I let another group so clearly by analyzing cross-infection transplantation on heterogeneous plants (rice, cassava, onions, eucalyptus and mail it), and gene sequencing of YgbK studies, which found that the disease was 25 I let so only on corn plants as green.้น 9 letter, while it was another disease can be so on another type of test plants with multiple infections into 4 groups: Group 1. I let that particular disease solution on plants rely on corn only. (The letter I-12 solo) 2 group. Can cause disease on onion with (7 AI Letter Sou) 3 group. Cause disease in both aromatic and mail it (let it 12 solo) and 4 groups promoters disease on mail it (let it 3 solo) while another group of the letter P. ananatis so it does not cause disease on maize (eucalyptus and pineapple) When developing the primers YgbK DNA band sizes found 596 genes bp can occur with P. ananatis corn group, only 34 so I let. These primers are specific tools that facilitate monitoring of P. ananatis I let corn seed solutions quickly, following precise. As a result, all studies show that bacteria cause disease in plants from seed corn it is P. ananatis which should be classified as Group 4, all other races, with additional analysis of specific genes, including the genes related to avr.
