Random amplified polymorphic DNA analysis of China isolates of Phytophthora parasitica var. nicotianae from different districts
China isolates of Phytophthora parasitica var. Nicotianae have been divided into three large pathogenic groups (PGS) (Hv(A), Iv(B), Wv(C)) which came from Yunnan, Shandong and Liaoning. These three districts belong to main tobacco regions in China: 15 isolates derived from Yunnan of the southwest, 13 isolates from Shandong of the east and 20 isolates from Liaoning of the northeast. PGS were det...
متن کاملCharacterization of Pseudomonas aeruginosa in Burn Patients Using PCR- Restriction Frag-ment Length Polymorphism and Random Amplified Polymorphic DNA Analysis
One of the major opportunistic pathogens in patients with burn injuries is Pseudomonas aeruginosa, which causes severe infections in burned patients. The objective of the study was to examine the molecular epidemiology of P. aeruginosa colonization in the burn unit of Shahid Motahari Hospital in Tehran, Iran. Restriction fragment length polymorphism (RFLP) and random amplified polymorphic DNA (...
متن کاملBABA and Phytophthora nicotianae Induce Resistance to Phytophthora capsici in Chile Pepper (Capsicum annuum)
Induced resistance in plants is a systemic response to certain microorganisms or chemicals that enhances basal defense responses during subsequent plant infection by pathogens. Inoculation of chile pepper with zoospores of non-host Phytophthora nicotianae or the chemical elicitor beta-aminobutyric acid (BABA) significantly inhibited foliar blight caused by Phytophthora capsici. Tissue extract a...
متن کاملFungicide Efficacy in Prevention of Root Rot Incited by Phytophthora cactorum and Phytophthora drechsleri in Fraser Fir Seedlings
The most serious disease problem in fraser fir (Abies fraseri) Christmas tree production is phytophthora root rot (PRR). The efficacies of six fungicide treatments in preventing PRR incited by Phytophthora cactorum and P. drechsleri in 2-year-old fraser fir seedlings were evaluated in 2010 and 2011 in central Pennsylvania. The study examined five fungicide drench treatments [dimethomorph, foset...
متن کاملRandom amplified polymorphic DNA (RAPD) fingerprinting of Mycoplasma gallisepticum isolates from chickens
Ten field isolates of Mycoplasma gallisepticum (MG) from different geographical areas of Iran were analyzed by random amplification of polymorphic DNA (RAPD). RAPD analysis produced reproducible banding patterns on the basis of which various distinct amplification patterns could be detected. MG isolates compared with reference strains (S6 and Mg SS) and vaccine strain (ts-11) and demonstrated...
