cDNA corresponding to the genomic segment 6 of avian rotavirus strain PO-13, which has group A common and subgroup I antigens, but does not hybridize in Northern blots with RNA probes from group A mammalian rotaviruses, was cloned and sequenced. When the deduced amino acid sequence was compared between strain PO-13 and eight group A mammalian rotaviruses,(More)
Arabidopsis belongs to the Brassicaceae family and plays an important role as a model plant for which researchers have developed fine-tuned genome resources. Genome sequencing projects have been initiated for other members of the Brassicaceae family. Among these projects, research on Chinese cabbage (Brassica rapa subsp. pekinensis) started early because of(More)
A genetic map for strain C of Escherichia coli was constructed, independently of that available for strain K-12 (Fig.2). The two maps are very similar. The origins of several Hfr derivatives of E. coli C were mapped. An F′ strain transferring the genes for histidine synthesis was isolated. Three different points of attachment (location, I, II and III) for(More)
Mouse sarcoma 180 cells have a polypeptide that has the same molecular weight as actin but it is more acidic than alpha-actin. Its tryptic peptide pattern on reversed-phase HPLC was very similar to that of beta + gamma-actin, an actin sample prepared by affinity chromatography on DNase I-Sepharose contained the acidic polypeptide, and monoclonal anti-actin(More)
The changes of protein kinases (PKs) in the nuclear matrix of HL-60 cells during the differentiation by retinoic acid (RA) were examined by in situ assay after sodium dodecyl sulfate-polyacrylamide gel electrophoresis. In the nuclear matrix of HL-60, at least seven species of PKs (83, 63, 58, 46, 42, 38, and 31 kDa) were always detected. Among these PKs, 63(More)
