In the fission yeast Schizosaccharomyces pombe, we found that the putative NO dioxygenase SPAC869.02c (named Yhb1) and the S-nitrosoglutathione reductase Fmd2 cooperatively reduced intracellular NO levels as NO-detoxification enzymes. Although both mRNA and protein levels were increased with exogenous NO, their expression patterns were different during(More)
As a cellular signaling molecule, nitric oxide (NO) is widely conserved from microorganisms, such as bacteria, yeasts, and fungi, to higher eukaryotes including plants and mammals. NO is mainly produced by NO synthase (NOS) or nitrite reductase (NIR) activity. There are several NO detoxification systems, including NO dioxygenase (NOD) and(More)
Fungal leaf blast, caused by Pyricularia oryzae, is a devastating disease of rice plants that annually causes severe production losses worldwide and is one of the top 10 fungal diseases that threaten global food security. Thus, a reliable control strategy against this disease is essential. In this study, the antagonistic activity of indigenous phyllosphere(More)
