Streptomyces saraceticus strain N45, a saprophytic Gram-positive bacteria, has been shown to harbor high chitinase activity. Due to its potential use in biological control, the cloning of chitinase genes and the development of methods to quickly and precisely detect its presence have become necessary. In this study, PCR-based random amplified polymorphic(More)
Citrus bacterial canker caused by Xanthomonas axonopodis pv. citri is a devastating disease resulting in significant crop losses in various citrus cultivars worldwide. A biocontrol agent has not been recommended for this disease. To explore the potential of bacilli native to Taiwan to control this disease, Bacillus species with a broad spectrum of(More)
We have shown the usefulness of the heteroduplex mobility assay (HMA) for phylogenetic analysis and for the discrimination of closely related Colletotrichum species. Because the heteroduplex mobility of a tested strain shows a unique banding pattern that is the function of the sequence of the referred strain, we further explored the potential use of(More)
The photodynamic effect of methionine-riboflavin mixture (MR) on membranous system of living cells was examined using rabbit red blood cells (RBCs) as an assay system. Evident increases of thiobarbituric acid (TBA) reactive substances, which reflected presumably the production of malondialdehyde (MDA) and the peroxidation of membrane lipid, were detected(More)
