Elicitation of anthocyanin production in callus cultures of Daucus carota and involvement of calcium channel modulators
The effect of fungal elicitors and calcium-channel modulators on the anthocyanin production in callus cultures of Daucus carota was studied. It was found that the addition of fungal elicitors resulted in higher anthocyanin accumulation on the 3rd day of culture, but they resulted in lower levels of anthocyanin on the 21st day. Fungal elicitor treatment also affected growth of the cultures, as e...
متن کاملIsolation and Characterization of Vacuoles from Cell Suspension Cultures of Daucus carota
A reliable procedure for the isolation o f vacuoles from anthocyanin-containing cells o f Daucus carota cell suspension cultures has been developed. From cells o f the late linear growth phase, protoplasts were prepared and purified in a sucrose/sorbitol gradient. Vacuoles were liberated from these protoplasts by osmotic shock and purified in a Metrizamide step gradient. The vacuolecontaining f...
متن کاملPurification and Interconversion of Homoserine Dehydrogenase from Daucus carota Cell Suspension Cultures.
Homoserine dehydrogenase from cell suspension cultures of carrot (Daucus carota L.) has been purified to apparent homogeneity by a combination of selective heat denaturation, ion exchange and gel filtration chromatographies, and preparative gel electrophoresis. Carrot homoserine dehydrogenase is composed of subunits of equal molecular weight (85,000 +/- 5,000). During purification, the enzyme e...
متن کاملTolerance and metabolism of phenol and chloroderivatives by hairy root cultures of Daucus carota L.
Hairy root cultures are shown to be suitable experimental systems to screen higher plants for tolerance to various inorganic and organic pollutants, and for determining the role of the root matrix in the uptake and further metabolism of contaminants. A number of clones were obtained by infection of carrot tissues with Agrobacterium rhizogenes and two (the fastest and the slowest growing root cl...
متن کاملIndigenous Production of Synthetic Seeds in Daucus Carota
Embryogenic callus culture of carrot (Daucus carota L.) was induced from the hypocotyl explants in MS medium supplemented with Casein hydrolysate, 2,4-D and BAP for somatic embryogenesis In vitro cell suspension cultures for high multiplication rate. Embryogenic callus was transferred to liquid basal Murashige and Skoog medium The mature somatic embryos were encapsulated in a Sodium alginate mi...
