We report here the draft genome sequence of Burkholderia gladioli strain NGJ1. The strain was isolated from healthy rice seeds and exhibits broad-spectrum antifungal activity against several agriculturally important pathogens, including Rhizoctonia solani, Magnaporthe oryzae, Venturia inaequalis, and Fusarium oxysporum.

Eighteen polymorphic microsatellite markers suitable for population genetic studies and protein kinase encoding genic variation measurement were developed for rice blast fungus Magnaporthe grisea. Polymorphism was evaluated by using 46 isolates collected from diverse geographical locations and rice varieties. Preliminary results indicate that each locus harbors two to

In our ongoing screening culture fluid extracts of Gloeoporus (Caloporus) dichrous strain 83065 inhibited the germination of Magnaporthe grisea and Fusarium graminearum spores. While isolating the active metabolites two new caloporosides, caloporoside G and caloporoside H, in addition to the known caloporoside derivatives F-16438G, caloporoside A, and 2-hydroxy-6-(16-hydroxyheptadecyl)benzoic a...

The whole-genome assembly of a unique rice isolate from India, Magnaporthe oryzae RMg-Dl that causes blast disease in diverse cereal crops is presented. Analysis of the 34.82 Mb genome sequence will aid in better understanding the genetic determinants of host range, host jump, survival, pathogenicity, and virulence factors of M. oryzae.

Non-host resistance (NHR) is the resistance of plants to a plethora of non-adapted pathogens and is considered as one of the most robust resistance mechanisms of plants. Studies have shown that the efficiency of resistance in general and NHR in particular could vary in different plant organs, thus pointing to tissue-specific determinants. This was exemplified by research on host and non-host in...

Exogenous application of the protein elicitors MoHrip1 and MoHrip2, which were isolated from the pathogenic fungus Magnaporthe oryzae (M. oryzae), was previously shown to induce a hypersensitive response in tobacco and to enhance resistance to rice blast. In this work, we successfully transformed rice with the mohrip1 and mohrip2 genes separately. The MoHrip1 and MoHrip2 transgenic rice plants ...

The aim of this study is a functional characterization of 10 putative histidine kinases (HIKs)-encoding genes in the phytopathogenic fungus Magnaporthe oryzae. Two HIKs were found to be required for pathogenicity in the fungus. It was found that the mutant strains ΔMohik5 and ΔMohik8 show abnormal conidial morphology and furthermore ΔMohik5 is unable to form appressoria. Both HIKs MoHik5p and M...

The rice blast fungus Magnaporthe oryzae is a model for studying fungal-plant interactions. Although it produces two types of spores (microconidia and macroconidia), previous infection studies have exclusively dealt with macroconidia. Germination of microconidia has not been reported, and their role in plant infection is not defined. Here we show that approximately 10% of microconidia germinate...
