Cyanobacterial Acclimation to Photosystem I or Photosystem II Light.
The organization and function of the photochemical apparatus of Synechococcus 6301 was investigated in cells grown under yellow and red light regimes. Broadband yellow illumination is absorbed preferentially by the phycobilisome (PBS) whereas red light is absorbed primarily by the chlorophyll (Chl) pigment beds. Since PBSs are associated exclusively with photosystem II (PSII) and most of the Ch...
متن کاملIn-vitro Antitumor Activity and Antifungal Activity of Pennogenin Steroidal Saponins from paris Polyphylla var. yunnanensis
Paris polyphylla Smith var. yunnanensis, has been used in traditional Chinese medicine for its antibiotic and anti-inflammatory properties; in addition it has been used to cure liver cancer in particular. In this current study, β-ecdysterone (1) and three pennogenin steroidal saponins (2-4) were isolated from the EtOH extract of Paris polyphylla var. yunnanensis, and then tested for their antit...
متن کاملResponses of Photosystem I Compared with Photosystem II to Fluctuating Light in the Shade-Establishing Tropical Tree Species Psychotria henryi
Shade-establishing plants growing in the forest understory are exposed to constant high light or fluctuating light when gaps are created by fallen trees. Our previous studies indicate that photosystem I (PSI) is sensitive to constant high light in shade-establishing tree species, however, the effects of fluctuating light on PSI and photosystem II (PSII) in shade-establishing species are little ...

متن کاملPolymorphic microsatellite markers in the traditional Chinese medicinal plant Paris polyphylla var. yunnanensis.
Paris polyphylla var. yunnanensis is a traditional Chinese medicinal plant and is listed as vulnerable by the IUCN. This medicinal herb is well known for its analgesic and anti-inflammatory properties, most notably as an ingredient of the hemostatic compound "Yunnan Baiyao". However, over-exploitation of the plant for economic purposes is pushing the species to the brink of extinction. Therefor...
