A novel thermostable mannanase from a newly isolated Bacillus pumilus GBSW19 has been identified, expressed, purified and characterized. The enzyme shows a structure comprising a 28 amino acid signal peptide, a glycoside hydrolase family 5 (GH5) catalytic domain and no carbohydrate-binding module. The recombinant mannanase has molecular weight of 45 kDa(More)
Agrobacterium tumefaciens-mediated transformation (ATMT) is becoming a popular effective system as an insertional mutagenesis tool in filamentous fungi. To gain more insight into the cellular and molecular mechanisms in the pathogenesis of Ustilaginoidea virens, the causal agent of rice false smut disease, a T-DNA insertion mutant library of U. virens was(More)
Recently, a growing number of researches have focused on the issues raised by the knowledge discovery of online information, particularly the problems of tracking topics, ideas, and users’ spreading influence across the Web. In this paper, the search-engine query logs on Topic Detection and Tracking (TDT) is analyzed other than study of the quality of(More)
Bacillussubtilis is well known for its biocontrol activity against several plant pathogens and for its role in promoting plant growth. HpaGXooc, from rice pathogenic bacterium Xanthomonasoryzae pv. oryzicola, is a member of the harpin group of proteins. It is known to elicit hypersensitive cell death in non-host plants, thereby inducing disease and insect(More)
