Two new oxazole/thiazole derivatives, named tetroazolemycins A (1) and B (2), have been isolated from the acetone extract of the mycelium of Streptomyces olivaceus FXJ8.012 derived from deep-sea water, together with three known compounds, spoxazomicins A-C (3-5), isolated from the fermentation supernatant. The planar structure and relative configuration of(More)
The genome-wide transcriptional responses of S. cerevisiae to heterologous carotenoid biosynthesis were investigated using DNA microarray analysis. The results show that the genes involved in metal ion transport were specifically up-regulated in the recombinant strain, and metal ions, including Cu2+, Fe2+, Mn2+, and Mg2+, were deficient in the recombinant(More)
Water uptake across cell membranes is a principal requirement for plant growth at both the cellular and whole-plant levels. Water movement through plant membranes is regulated by aquaporins. We examined the expression of the OsAQP gene, encodes a tonoplast intrinsic protein (TIP), which was isolated from a rice panicle cDNA library. Semi-quantitative RT-PCR(More)
INTRODUCTION Cell nuclei are important indicators of cellular processes and diseases. Segmentation is an essential stage in systems for quantitative analysis of nuclei extracted from microscopy images. Given the wide variety of nuclei appearance in different organs and staining procedures, a plethora of methods have been described in the literature to(More)
Five new dibenzoxazepinone derivatives, mycemycins A-E (1-5), were isolated from the ethanol extracts of mycelia of two different streptomycetes. 1 and 2 were isolated from an acidic red soil-derived strain, Streptomyces sp. FXJ1.235, and 3-5 from a gntR gene-disrupted deep-sea strain named Streptomyces olivaceus FXJ8.012Δ1741. The structures of mycemycins(More)
Staphylococcus aureus is an important human pathogen that causes a variety of diseases, ranging from localized skin infections to life-threatening systemic infections. The success of S. aureus as a pathogen is partly due to its ability to adhere to a wide range of host tissues by binding to host extracellular matrix proteins such as fibrinogen, fibronectin,(More)
