In Streptomyces coelicolor, bldG encodes a putative anti-anti-sigma factor that regulates both aerial hypha formation and antibiotic production, and a downstream transcriptionally linked open reading frame (orf3) encodes a putative anti-sigma factor protein. A cloned DNA fragment from Streptomyces clavuligerus contained an open reading frame that encoded a protein showing 92% identity to the S....
A novel mycovirus belonging to the proposed family “Fusariviridae” was discovered in Alternaria solani by sequencing a cDNA corresponding double-stranded RNA extracted from this phytopathogenic fungus. The virus tentatively named “Alternaria fusarivirus 1” (AsFV1). AsFV1 has single-stranded positive-sense (+ssRNA) genome of 6845 nucleotides containing three open reading frames (ORFs) and poly(A...
The phoM gene is one of the positive regulatory genes for the phosphate regulon of Escherichia coli. We analyzed the nucleotide sequence of a 4.7-kilobase chromosomal DNA segment that encompasses the phoM gene and its flanking regions. Four open reading frames (ORFs) were identified in the order ORF1-ORF2-ORF3 (phoM)-ORF4-dye clockwise on the standard E. coli genetic map. Since these ORFs are p...
Among oncogenic adenoviruses, human adenovirus type 9 (Ad9) is unique in eliciting exclusively estrogen-dependent mammary tumors in rats and in not requiring viral E1 region transforming genes for tumorigenicity. Instead, studies with hybrid viruses generated between Ad9 and the closely related nontumorigenic virus Ad26 have roughly localized an Ad9 oncogenic determinant(s) to a segment of the ...
Chronic bee paralysis virus (CBPV) is responsible for chronic paralysis, an infectious and contagious disease of adult honey bees (Apis mellifera L.). The full-length nucleotide sequences of the two major RNAs of CBPV have previously been characterized. The Orf3 of RNA1 has shown significant similarities to the RNA-dependent RNA polymerase (RdRp) of positive single-stranded RNA viruses, whereas...
OBJECTIVE Bombyx mori parvo-like virus is a type of virus containing two single-stranded linear DNA molecules (VD1, VD2). In the present work, the structural proteins of B. mori parvo-like virus (China Zhenjiang isolate) (BmDNV-Z) were identified. METHODS The virions were purified by cesium chloride density gradient centrifugation from the feces of B. mori larvae infected with BmDNV-Z and ana...
A cloned 2.5 kb DNA fragment that can restore antibiotic production and sporulation to a bldG mutant encodes a 113 aa protein showing similarity to a family of anti-anti-sigma factors from Bacillus and Staphylococcus; and the deduced product of a closely spaced downstream ORF, designated ORF3, shows similarity to cognate anti-sigma factors. The homologues in Bacillus regulate the activity of sp...
Intersubspecific hybrid sterility is a common form of reproductive isolation in rice (Oryza sativa L.), which significantly hampers the utilization of heterosis between indica and japonica varieties. Here, we elucidated the mechanism of S7, which specially causes Aus-japonica/indica hybrid female sterility, through cytological and genetic analysis, map-based cloning, and transformation experime...
