Eight antagonistic bacteria against Xanthomonas oryzae pathovar oryzae as well as the causal bacterial leaf blight disease in rice, have been isolated from rice phyllosphere of Wonogiri and Sukoharjo Regency, Central Java, Indonesia, using dual plate method. The aims of this study were to identify molecularly of 16S rDNA and polyketide synthase (PKS) genes of antagonist bacteria. The PKS gene is recorded as one of antibiotic compounds class which encode the polyketide biosynthesis. The amplification of 16S rDNA gene was performed using 63f and 1387r primers, while PKS gene detection was performed using degKS2F.gc and degKSR5.gc primers. The nucleotide sequences of 16S rDNA and PKS genes was aligned using GenBank database and BLAST-N program from NCBI site was operated. The results showed that the eight isolates identity of SH2a, MO142, MO22g, MO34h, MO34i, MO34j, MO43a and MO63j were Pseudomonadaceae SH2a, Pantoea sp. MO142, Pantoea sp. MO22g, Erwinia sp. MO34h, Pantoea sp. MO34i, Pantoea sp. MO34j, Pantoea sp. MO43a and Pantoea sp. MO63j, respectively. Bacterial antagonists of PKS genes have similarities with the gene of nonribosomal peptide synthetase-polyketide synthase hybrid (cpbI) Lysobacter lactamgenus. This indicates that the antagonist mechanism of antagonist bacteria is antibiosis.","PeriodicalId":101708,"journal":{"name":"Asian Journal of Plant Pathology","volume":"4 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2015-04-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"123175219","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

The tested concentrations of humic acid had no inhibitory effect on Phytophthora infestans. While, thyme at concentrations 8.0 mL LG caused complete inhibition in linear growth of P. infestans. The highest inhibition in linear growth was obtained with thyme at 6.0 mL LG which reduced the linear growth by 92.2%. Moreover, under field conditions, results revealed that the most effective treatments are humic acid at 6.0 or 8.0 g LG combined with thyme at 6.0 or 8.0 mL LG which reduced the late blight incidence more than 81.3 and 78.4% during first and second growing seasons, respectively.

During field survey, a potential charcoal rot pathogen Macrophomina phaseolina was isolated and identified. About 10 different rhizosphere soils of healthy groundnut plants were selected for isolation of fungi. Among 25 isolates assayed for antagonism, ten different fungi significantly inhibited colony growth of M. phaseolina in dual culture plates and morphological identification was done at (400X). Antagonistic fungi inflicted 25.6-41% mycelial growth inhibition in M. phaseolina. Colony growth and sclerotia production of M. phaseolina ceased effectively by Emericella nidulans and E. rugulosus, respectively. Mutual inhibition between Alternaria alteranata, Aspergillus flavus, A. terreus, Penicillium chrysogenum and M. phaseolina was observed.
