FRET as a tool for the studies of structural changes in full-length bacterial phytochrome, Agp1

Bacteriophytochromes (BphPs) are light-regulated biliprotein photoreceptors widely occurring in bacteria. BphPs exists in two spectral distinct states: the red-light absorbing state (Pr) and the far-red light-absorbing state (Pfr). BphPs are composed of an N-terminal photosensory core module and a light-controlled C-terminal histidine kinase module. The detailed mechanism on how photoconversion, initiated by a...

Root and hypocotyl growth of Arabidopsis seedlings grown under different light conditions and influence of TOR kinase inhibitor AZD

We set up six light conditions to investigate the changes in the development of Arabidopsis thaliana hypocotyls and roots. Seedlings grown for 96 h under darkness were scored with shorter roots and longer hypocotyls. In shoot-shaded conditions, seedlings were unable to carry out photosynthesis, resulting in insufficient stored nutrients for root development. In the three groups of different light intensities applied to...

Gene regulating effects of Cymbopogon citratus on glucose metabolism of normal albino rats

Cymbopogon citratus has been reported to have hypoglycaemic and antidiabetic activities. This study evaluates the insulinotropic properties of C. citratus via gene expression. C. citratus was administered to normal rats as pulverized leaves (2, 10 and 30%) mixed with animal feed for one week; as aqueous and ethanol extracts at a dosage of 30 and 100 mg/kg body weight for 30 days; and as isolated saponins, flavonoids and...
