Blue egg coloring is attributed to biliverdin derived from the oxidative degradation of heme through catalysis by heme oxygenase (HO). The pigment is secreted into the eggshell by the shell gland. There is uncertainty as to whether the pigment is synthesized in the shell gland or in other tissues. To investigate the site of pigment biosynthesis, the expression of heme oxygenase (decycling) 1 (H...

4', 6-diamidino-2-phenylindole dihydrochloride (DAPI) is a DNA dye widely used to mark and trace stem cells in therapy. We here studied the effect of DAPI staining on the behavior of mesenchymal stem cells cultured in either a control, non-osteogenic medium or in an osteogenic differentiation medium. In the control medium, the number of stem cells/field, as well as the number of fluorescent cel...

Diversification of cone pigment spectral sensitivities during evolution is a prerequisite for the development of color vision. Previous studies have identified two naturally occurring mechanisms that produce variation among vertebrate pigments by red-shifting visual pigment absorbance: addition of hydroxyl groups to the putative chromophore binding pocket and binding of chloride to a putative e...

this research was aimed to investgate the effect of light quality on micropropagation of pear rootstock oh×f333. first, single nodes explants were cultured in modified ql medium containing ba at four levels (0, 0.5, 1, and 2 mg/l-1) and iaa at three levels (0, 0.1, and 1 mg/l-1) and were evaluated for shoot proliferation. then, plantlets subcultured in modified ql medium containing 1 mg/l-1 ba ...

The effect of high pressure treatment on biochemical changes during storage was investigated using Brassica rapa root. High pressure treated samples with 400 and 600 MPa formed unique green-blue color during 7-d storage at 4 degrees C. The mechanism of green-blue compound formation would be based on biochemical pathway for a unique green-blue pigment synthesis, containing O2-dependent steps and...

This study aims to reconcile industrially suitable strains of higher red pigment producing Monascus purpureus MPA5 and Monacolin K ruber MRA7, were tried fuse for development increased efficacy targeted secondary metabolites production. The optimum concentration protoplast mixture was standardized, before the fusion experiment. effective observed with solution 30 % PEG 6000, CaCl2.2H2O (0.01 M)...

The article presents the results of studying effect light-emitting diodes (LEDs) on efficiency micropropagation valuable woody plants. Commercial use requires optimization various parameters, including light quality and lighting regime. Nowadays, LED have become an alternative source illumination for plant tissue culture, Recently, along with medicinal herbaceous plants, tree crops also widely ...

In studies on the induction of gene mutations by high energy radiation from the Bikini atom bomb, X-ray and other sources, a large number of seedling cultures have been grown for observation. Since January, 1949, maize seedling cultures have been observed by the use of filtered ultraviolet light. Normal seedlings viewed by ultraviolet light have a dull reddish-purple appearance due to the red f...

Green fluorescent protein (GFP)-like pigments have been proposed to have beneficial effects on coral photobiology. Here, we investigated the relationships between green fluorescence, coral heating and tissue optics for the massive coral Dipsastraea sp. (previously Favia sp.). We used microsensors to measure tissue scalar irradiance and temperature along with hyperspectral imaging and combined i...
