Many bioactive natural products are produced as "secondary metabolites" by plants, bacteria, and fungi. During the middle of the 20th century, several secondary metabolites from fungi revolutionized the pharmaceutical industry, for example, penicillin, lovastatin, and cyclosporine. They are generally biosynthesized by enzymes encoded by clusters of(More)
Umbelopsis isabellina is a fungus in the subdivision Mucoromycotina, many members of which have been shown to be oleaginous and have become important organisms for producing oil because of their high level of intracellular lipid accumulation from various feedstocks. The genome sequence of U. isabellina NBRC 7884 was determined and annotated, and this(More)
Ustilaginoidea virens is a rice pathogenic fungus that causes false smut disease, a disease that seriously damages the yield and quality of the grain. Analysis of the U. virens IPU010 33.6-Mb genome sequence will aid in the understanding of the pathogenicity of the strain, particularly in regard to effector proteins and secondary metabolic genes.
Fatty acids are attractive molecules as source materials for the production of biodiesel fuel. Previously, we attained a 2.4-fold increase in fatty acid production by increasing the expression of fatty acid synthesis-related genes in Aspergillus oryzae. In this study, we achieved an additional increase in the production of fatty acids by disrupting a(More)
