Cold tolerance at the early seedling stage of rice is one of the major determinants for uniform seedling growth. The trait is complex and controlled by quantitative trait loci (QTLs). In this study, a linkage map consisting of 129 SSR markers was constructed, spanning 2,051.1 cM with ranging from 4.3 to 36.5 cM between adjacent markers. QTLs analysis at the(More)
Burkholderia sp. strain SJ98 (DSM 23195) utilizes 2-chloro-4-nitrophenol (2C4NP) or para-nitrophenol (PNP) as a sole source of carbon and energy. Here, by genetic and biochemical analyses, a 2C4NP catabolic pathway different from those of all other 2C4NP utilizers was identified with chloro-1,4-benzoquinone (CBQ) as an intermediate.

N-Acetylglucosamine-1-phosphate uridyltransferase (GlmU) catalyzes the formation of UDP-GlcNAc, a fundamental precursor in cell wall biosynthesis. GlmU represents an attractive target for new antibacterial agents. In this study, a theoretical three-dimensional (3D) structure of GlmU from Xanthomonas oryzae pv. oryzae (Xo-GlmU) was generated, and the(More)
Enoyl-acyl carrier protein (ACP) reductase (ENR) is an attractive and potential target for developing selective antibacterial agents. Recent studies showed that FabK is the sole isoform of ENR in Streptococcus pneumoniae, and at the same time an X-ray crystallographic study of FabK from S. pneumoniae (SpFabK) was reported for the first time. Based on above(More)
By structure-based virtual screening and experimental verification, two Chinese medicine monomers, luteolin and curcumin, had been proved to be uncompetitive inhibitors of enoyl-ACP reductase from Escherichia coli (EcFabI) with the inhibition constant (K(i)) of 7.1microM and 15.0microM, respectively. In particular, curcumin had apparent antibacterial(More)
The observations that Lymphopenia is common in severe acute respiratory syndrome (SARS) patients and that peripheral blood mononuclear cell (PBMC) could be infected by SARS-CoV indicate that PBMC could be useful in identifying the gene expression profile in convalescent patients and tracing the host response to SARS-CoV infection. In this study, the altered(More)
Rhodococcus imtechensis RKJ300 (DSM 45091) grows on 2-chloro-4-nitrophenol (2C4NP) and para-nitrophenol (PNP) as the sole carbon and nitrogen sources. In this study, by genetic and biochemical analyses, a novel 2C4NP catabolic pathway different from those of all other 2C4NP utilizers was identified with hydroxyquinol (hydroxy-1,4-hydroquinone or(More)
para-Nitrophenol (PNP), 3-methyl-4-nitrophenol (3M4NP), and 2-chloro-4-nitrophenol (2C4NP) are highly toxic compounds that have caused serious environmental issues. We inoculated an artificially contaminated soil with Burkholderia sp. strain SJ98, which has the ability to degrade PNP, 3M4NP, and 2C4NP, and quantified bioremediation. There was accelerated(More)
