Quantification of cyclic and linear flows in plants.
A method was developed to quantify the fraction of photosystem I (PSI) centers that operate according to the cyclic or linear mode, respectively. P(700) and plastocyanin oxidation were analyzed under a weak far-red excitation (approximately eight photons per s(-1) per PSI) that induces P(700) oxidation in approximately 20 s and approximately 3 s in dark-adapted and preilluminated leaves, respec...
متن کاملEnergy storage of linear and cyclic electron flows in photosynthesis.
The energy storage of photosynthesis in the green alga Chlorella vulgaris was determined by pulsed, time-resolved photoacoustics. The energy storage of the linear electron transfer process in photosynthesis, of cyclic photosystem (PS) I, and possibly of PSII was determined by selection of excitation wavelength and of flash interval. At 695 nm excitation, a rather large cyclic PSI energy storage...
متن کاملRegulation of cyclic and linear electron flow in higher plants.
Cyclic electron flow is increasingly recognized as being essential in plant growth, generating a pH gradient across thylakoid membrane (ΔpH) that contributes to ATP synthesis and triggers the protective process of nonphotochemical quenching (NPQ) under stress conditions. Here, we report experiments demonstrating the importance of that ΔpH in protecting plants from stress and relating to the reg...

15 صفحه اولQuantification of Gallic Acid in Fruits of Three Medicinal Plants
Triphala is a traditional herbal formulation consisting of dried fruits originating from three medicinal plants, namely Terminalia chebula, Terminalia bellirica and Phyllanthus embelica. It is used in folk medicine for the treatment of headaches, dyspepsia and leucorrhoea. There are some reports regarding Triphala"s pharmacological effects including its anti-cancer, radioprotective, hypocholest...
