Different cryptic plasmids are widely distributed in many strains of cyanobacteria. A small cryptic plasmid, pCA2.4, from Synechocystis strain PCC 6803 was completely sequenced, and its replication mode was determined. pCA2.4 contained 2,378 bp and encoded a replication (Rep) protein, designated RepA. An analysis of the deduced amino acid sequence revealed(More)
Both strands of small plasmid pCB2.4 from the unicellular cyanobacterium Synechocystis PCC 6803 have been sequenced and analyzed. pCB2.4 contains 2345 bp and 57% A+T. Three open reading frames (ORFs) were identified in the nucleotide sequence of one strand of pCB2.4. ORF1 and ORF3 may encode basic proteins with calculated pI values of 7.71 and 9.96,(More)
MYB transcription factors play important roles in the abiotic stress response in plants, but their characteristics and functions in buckwheat (Fagopyrum tataricum) have not been fully investigated. Here, a novel R2R3-type MYB gene, designated FtMYB12, was isolated from the cultivated tartary buckwheat F. tataricum. Using quantitative real-time PCR, we found(More)
Little knowledge of DNA replication in cyanobacteria is available. In this study, we report the development and characterization of an in vitro system for studies of replication of the endogenous plasmids from the unicellular cyanobacterium Synechocystis 6803. This system (fraction III) was isolated at high salt concentrations and partially purified on a(More)
