5. Identification of pathogenic bacteria of Maize with specific primers by technical Bio - polymerase chain reaction (PCR)
from ใช้เทคนิค. Bio-PCR to check the size of the specific gene 16S rDNA infections of Aaa, the 16S-23S ITS of P infections.Ananatis using Aaa infections and ananatis Erwinia PV. Ananatis from stock Culture Department of plant diseases and plant protection research group, Department of agriculture, simple tea Is a species of primers specific subsp A.avenae infections.Avenae (AcAVF 5. '-' AcAVR GGCTGGATCACCTCCTTTC-3 and 5 '- ACTTGCGAGGTCTTTCACC-3') (Nan District medicine, 2551) and specific primers Pantoea ananatis. (PanITS sn2b 5 'GTC TGA TAG AAA GAA AAG AAG3' PanITS as2b and 5 'TTC ATA TCA CCT TAC CGG CGC3') (Coutinho et, al.2002), it was found that the primer and the reaction it can increase the amount of DNA fragments of bacteria target (picture 1) by pairs of primer. AcAVF AcAVR and can increase the amount of DNA fragments of the bacteria in the J.And 615 BP primer and PanITS sn2b PanITS as2b can increase the amount of DNA fragments of the bacteria in the H by size 398 BP DNA bands.
