The cyanobacterium Synechocystis sp. PCC 6803 was the first phototrophic organism to be fully sequenced. The genomic sequence has revealed the structure of the genome and its gene constituents (3167 genes), as well as the relative map positions of each gene.

Synechocystis sp. PCC6803 is a strain of unicellular, freshwater cyanobacteria. Synechocystis sp. PCC6803 is capable of both phototrophic growth by oxygenic photosynthesis during light periods and heterotrophic growth by glycolysis and oxidative phosphorylation during dark periods. [2]

为探究细胞大小对光合活性的具体影响研究以集胞藻 (Synechocystis sp.)PCC 6803为对象, 比较了野生型与体积增大突变体的光合活性。结果表明, 小细胞由于较大的比表面积, 具备更高的单位体积叶绿素 a 浓度和叶绿素 a 特异性吸光系数。但其总体叶绿素储量不足及反应中心容量有限, 高光条件下光量子利用效率偏低。大细胞虽在物质交换和光捕获方面存在限制, 但其通过优化光量子的吸收、利用和分配, 在高光条件下呈现出更高的光合作用效率和更好的适应性, 具体表现为更高的 …

3 天之前 · We have shown previously that expressing the ChlF subunit of Chroococcidiopsis thermalis PCC 7203 in the model cyanobacterium Synechocystis sp. PCC 6803 (Syn6803) is sufficient to drive the production of chlorophyll f (Chl f), but only to low levels (0.24% Chl f/Chl a).

The cyanobacteriumSynechocystis sp. PCC 6803 is readily amenable to targeted mutagenesis: Foreign DNA is taken up spontaneously, and after uptake DNA can be integrated into the organism's genome by homologous recombination.

2017年12月7日 · Synechocystis sp. PCC 6803 is a widely used model cyanobacterium, whose substrains can vary on both genotype and phenotype levels. Previously described phenotypic variations include ability of mixotrophic growth, ability of movement on agar plates and variations in pigments composition or cell size.

The cyanobacterium Synechocystis sp. PCC 6803 was the first phototrophic organism to be fully sequenced. The genomic sequence has revealed the structure of the genome and its gene constituents (3167 genes), as well as the relative map positions of each gene.

1982年4月1日 · Strain 6803 might be useful as a test organism for taxonomic analysis via transformation of new isolates in the Synecho- cystis genus. This strain of Synechocystis sp. seems to be a promising recipient for studies of plasmid transformation and for the elaboration of gene cloning systems.

Sequence analysis of the genome of the unicellular cyanobacterium Synechocystis sp. strain PCC6803. I. Sequence features in the 1 Mb region from map positions 64% to 92% of the genome. Journal: DNA Res 2:153-66, 191-8 (1995)

2025年3月15日 · Where, Y e is an actual experimental value, Y p is a predicted experimental value, moreover N is number of test samples.. 2, 2-diphenyl-1-picrylhydrazyl (DPPH) assay. Free radical scavenging activity of the extracted pigment of Synechocystis sp. PCC 6803 was determined using 2, 2-diphenyl-1-picrylhydrazyl (DPPH) assay [].The ANN-MOGA optimized pigment extracts were obtained from cell pellets ...
