Innate immunity to microorganisms relies on the specific sensing of pathogen-associated molecules by host recognition receptors. Whereas studies in animals have largely focused on the recognition of extracellular pathogen-associated molecules by the TLR (toll-like receptor) superfamily, few studies have been carried out in plants, and it is not understood how these molecules are secreted or mod...

BACKGROUND The organic acid producer Aspergillus oryzae and Rhizopus delemar are able to convert several alternative carbon sources to malic and fumaric acid. Thus, carbohydrate hydrolysates from lignocellulose separation are likely suitable as substrate for organic acid production with these fungi. RESULTS Before lignocellulose hydrolysate fractions were tested as substrates, experiments wit...

Acidovorax avenae subsp. avenae is a phytobacterium which is the causative agent of several plant diseases with economic significance. Here, we present the draft genome sequence of strain RS-1, which was isolated from rice shoots in a rice field in China. This strain can cause bacterial stripe of rice.

Pectates lyase (Pel) plays an important role in bacteria pathogenicity. The crystal structure of Pel from Acidovorax citrulli (AcPel) has been solved to 1.37 Å resolution. AcPel belongs to the polysaccharide lyase family 1 (PL1), which has a characteristic right-handed β-helix fold. AcPel is similar with other Pels in the PL1 family, but also shows some differences at the substrate binding site.

Aspergillus oryzae glucoamylases encoded by glaA and glaB, and Rhizopus oryzae glucoamylase, were displayed on the cell surface of sake yeast Saccharomyces cerevisiae GRI-117-UK and laboratory yeast S. cerevisiae MT8-1. Among constructed transformants, GRI-117-UK/pUDGAA, displaying glaA glucoamylase, produced the most ethanol from liquefied starch, although MT8-1/pUDGAR, displaying R. oryzae gl...

flour beetles, Tribolium confusum. Efficacy was assessed on wheat and maize at three dosages of spinosad dust formulation (corresponding to 0.0625, 0.1875 and 0.625ppm of active ingredient [AI] for S. oryzae and to 0.1875, 0.625 and 1.25 ppm of AI for T. confusum), alone or combined with SilicoSec at 150ppm for S. oryzae and 250 ppm for T. confusum. The mortality of S. oryzae exposed for 14d on...

ninety one monoconidial bipolaris isolates were obtained from lesions on different parts of rice in different locations of mazandaran province during the summer of 2009. bipolaris species were identified using morphological features such as color and shape of colony and color and size of conidia and conidiophores. the isolates were separated into two species; 85 (93.4%) isolates belonged to bip...

Kosakonia oryzae KO348 is an endophytic and plant growth-promoting strain isolated from the roots of rice in Italy. Here, we report the draft genome sequence of Kosakonia oryzae KO348.
