cyAbrB is a transcriptional regulator unique to and highly conserved among cyanobacterial species. A gene-disrupted mutant of cyabrB2 (sll0822) in Synechocystis sp. PCC 6803 exhibited severe growth inhibition and abnormal accumulation of glycogen granules within cells under photomixotrophic conditions. Within 6 h after the shift to photomixotrophic conditions, sodium bicarbonate-dependent oxyge...

Capillary electrophoresis mass spectrometry (CE/MS) was applied for the comprehensive survey of changes in the amounts of metabolites upon the shift from photoautotrophic to photomixotrophic conditions in Synechocystis sp. PCC 6803. When glucose was added to the photoautotrophically grown culture, the increase in the metabolites for the oxidative pentose phosphate (OPP) pathway and glycolysis, ...

The volatile shoot oil o f Coleonema album was found to be composed o f monoterpenes, ses­ quiterpenes and phenylpropanoids. Heterotrophic and photomixotrophic callus cultures were established from green parts o f the plant. A photomixotrophic cell line contained a heteroge­ neous population o f plastids and synthesized an essential oil, which differed qualitatively and quantitatively from the ...

plantlets grown in conventional tissue culture systems usually encounter physiological and anatomical abnormalities including inability to photosynthesize, low chlorophyll content, open stomata, lack of a cuticle layer in the leaf, abnormal xylem parenchyma etc. photoautotrophic and photomixotrophic systems could diminish these problems. the purpose of this study was to increase the chlorophyll...

Lupinus, Baptisia, Sarothamnus, Diumal Rhythm, Photomixotrophic Cell Suspension Cultures, Quinolizidine Alkaloids Fluctuations of quinolizidine alkaloid content in leaflets of Lupinus polyphyllus, L. hartwegii, Baptisia australis, and Sarothamnus scoparius were studied over a 36 h period. The alkaloid contents reached their maximum at noon or early afternoon, and their minimum during the night....

A biotechnological system for the production of plants biomass and phenylpropanoids maqui was developed in photomixotrophic TIBs. The vitro multiplication evaluated using combinations TDZ BAP TIBs 1L capacity. Treatment MS basal supplemented with 1 mg/L shows best results variables fresh weight rate. Photomixotrophic conditions were standardized media 3%, 2%, 1%, 0% sucrose at a light intensity...

Soybean (Glycine max [L.] Merr.) suspension cultures grown under photoautotrophic and photomixotrophic (1% sucrose) culture conditions were used in 14CO2 pulse-chase experiments to follow cell-wall polysaccharide and starch biosynthesis and turnover. Following a 30-min pulse with 14CO2, about one-fourth of the 14C of the photoautotrophic cells was incorporated into the cell wall; this increased...
