  The regulation of recA expression occurs both at transcriptional and post-transcription levels in Synechocystis sp. PCC (Oliveira and Lindblad, ). In cyanobacteria, LexA regulate multiple processes such as oxidative stress, fatty acid and toxins biosynthesis and heavy metal tolerance (Kumar et al., ).Cited by: 3. Advances in Cyanobacterial Biology presents the novel, practical, and theoretical aspects of cyanobacteria, providing a better understanding of basic and advanced biotechnological application in the field of sustainable agriculture. Chapters have been designed to deal with the different aspects of cyanobacteria including their role in the evolution of life, cyanobacterial diversity and Price: $ The expression of the cyanobacterial recA gene, isolated from Anabaena variabilis, has been examined at the levels of transcript and protein abundance. Exposure of the cyanobacterium to a variety of DNA-damaging agents, including mitomycin C, methyl methanesulfonate, and UV irradiation, results in a rapid increase in the abundance of the recA Cited by: Briggs LM, Pecoraro VL and Mcintosh L () Copper-induced expression, cloning, and regulatory studies of the plastocyanin gene from the cyanobacterium Synechocystis .

However, in the cyanobacteria, in the chloroplasts of the eucaryotic red algae, and in the cyanelles of certain phylogenetically ambiguous eucaryotes such as Cyanophora paradoxa, the light-harvesting antenna complexes for Photosystem II are large, multiprotein complexes composed of water-soluble proteins, the phycobilisomes, which are attached. Part of the Advances in Experimental Medicine and Biology book series (AEMB but instead will focus on the genetic tools and the inherent aspects of cellular physiology that influence gene expression in cyanobacteria. Cassier-Chauvat C () Function and regulation of the cyanobacterial genes lexA, recA and ruvB: LexA is critical to the.   A practical antibiotics-free plasmid expression system in cyanobacteria was developed by using the complementation of cyanobacterial recA null mutation with the Escherichia coli recA gene on the plasmid. This system was applied to the production of polyhydroxyalkanoate (PHA), a biodegradable plastic, and the transgenic cyanobacteria stably maintained the pha genes for PHA . Identification and Expression Analysis of cDNA Encoding a Chloroplast Recombination Protein REC1, the Chloroplast RecA Homologue in Chlamydomonas .

To enable circadian control of gene expression in cyanobacteria, we constructed a genetic logic gate (NAND) using orthogonal promoters via modular CRISPR interference. The NAND gates were tested in Synechococcus elongatus PCC using a fluorescent reporter. The NAND gate dynamics were characterized based on the affinity of the dCas9 complex to the output element. Upon connecting tight . Cyanobacteria are an ancient group of prokaryotes with an immense impact on the evolution of other organisms and the global ecosystem. In this chapter, I will focus on a genetically diverse yet morphologically similar group of cyanobacteria merged under the name er with Prochlorococcus, Synechococcus may be the most abundant cyanobacterium and amongst the most .   The complete nucleotide sequence of the Agrobacterium tumefaciens recA gene was determined. A comparison of the translated open reading frame of the gene with other known recA sequences revealed significant sequence conservation. However, unlike its Escherichia coli equivalent, A. tumefaciens recA lacks the upstream ‘SOS box’, suggesting a different mechanism of regulation for . The expression of the cyanobacterial recA gene, isolated from Anabaena variabilis, has been examined at the levels of transcript and protein abundance. Exposure of the cyanobacterium to a variety of DNA-damaging agents, including mitomycin C, methyl methanesulfonate, and UV irradiation, results in a rapid increase in the abundance of the recA.
