Marine fungi producing antifungal compounds were screened against Pyricularia oryzae (P. oryzae), and a metabolite of marine fungus M-3 isolated from laver (Porphyra yezoensis) showed potent activity. Novel diketopiperazine (1) was isolated from the culture extracts, and its structure was elucidated by spectroscopic methods. The MIC of 1 against P. oryzae was 0.36 microM.
Xanthomonas oryzae pv. oryzae is the causal agent of bacterial leaf blight, one of the most serious diseases in rice. X. oryzae pv. oryzae Philippine race 6 (PR6) strains are unable to establish infection in rice lines expressing the resistance gene Xa21. Although the pathogen-associated molecule that triggers the Xa21-mediated defense response (AvrXa21) is unknown, six rax (required for AvrXa2...
In Xanthomonas oryzae pv. oryzae, the causal agent of bacterial leaf blight of rice, HrpXo is known to be a transcriptional regulator for the hypersensitive response and pathogenicity (hrp) genes. Several HrpXo regulons are preceded by a consensus sequence (TTCGC-N(15)-TTCGC), called the plant-inducible promoter (PIP) box, which is required for expression of the gene that follows. Thus, the PIP...
Xanthomonas oryzae pv. oryzae causes bacterial blight, a serious disease of rice. Our analysis revealed that the X. oryzae pv. oryzae genome encodes genes responsible for iron uptake through FeoB (homolog of the major bacterial ferrous iron transporter) and a siderophore. A mutation in the X. oryzae pv. oryzae feoB gene causes severe virulence deficiency, growth deficiency in iron-limiting medi...
The landraces and wild species wisely choose their microbiome explored them as a second genome for nutrient acquisition from the limited resources of soil ecosystem can withstand drought diseases. Hence, present study aimed to explore drought-tolerant rice landrace Tamil Nadu putative competitive endophytes develop plant-growth-promoting endophytic bacterial inoculant. Twenty two were authentic...
Aqueous and Solvent extracts of leaves of S. torvum viz., Petroleum ether, Benzene, Chloroform, Methanol and Ethanol were tested in vitro for antimicrobial activity following the procedures of poisoned food technique and cup diffusion method against some important seed borne pathogens of paddy viz, Pyricularia oryzae, Alternaria alternata, Bipolaris oryzae, Tricoconis padwickii, Dreschlera tetr...
Magnaporthaceae is a family of ascomycetes that includes three fungi of great economic importance: Magnaporthe oryzae, Gaeumannomyces graminis var. tritici, and Magnaporthe poae. These three fungi cause widespread disease and loss in cereal and grass crops, including rice blast disease (M. oryzae), take-all disease in wheat and other grasses (G. graminis), and summer patch disease in turf grass...
Aspergillus oryzae is a common fungus for traditional fermentation in Asia, such as spirit, soybean paste, and soy sauce fermentation. We report the 36.7-Mbp draft genome sequence of A. oryzae 100-8 and compared it to the published genome sequence of A. oryzae 3.042.
A Myceliophthora thermophila laccase and a Rhizoctonia solani laccase were mutated on a pentapeptide segment believed to be near the type-1 Cu site. The mutation L513F in Myceliophthora laccase and the mutation L470F in Rhizoctonia laccase took place at a position corresponding to the type-1 Cu axial methionine (M517) ligand in Zucchini ascorbate oxidase. The triple mutations V509L,S510E,G511A ...
