Photosynthesis-dependent but neochrome1-independent light positioning of chloroplasts and nuclei in the fern Adiantum capillus-veneris.
Chloroplasts change their positions in the cell depending on the light conditions. In the dark, chloroplasts in fern prothallia locate along the anticlinal wall (dark position). However, chloroplasts become relocated to the periclinal wall (light position) when the light shines perpendicularly to the prothallia. Red light is effective in inducing this relocation in Adiantum capillus-veneris, an...
متن کاملFern constituents: triterpenoids from Adiantum capillus-veneris.
Two new migrated hopane triterpenoids, viz. 4alpha-hydroxyfilican-3-one and fern-9(11)-en-12beta-ol, and olean-18-en-3-one and olean-12-en-3-one as the first example of oleanane compounds from Adiantum ferns were isolated along with many other known triterpenoids from Adiantum capillus-veneris of China and Egypt. Their structures were elucidated by spectroscopic analyses.
متن کاملPhototropins and neochrome1 mediate nuclear movement in the fern Adiantum capillus-veneris.
In gametophytic cells (prothalli) of the fern Adiantum capillus-veneris, nuclei as well as chloroplasts change their position according to light conditions. Nuclei reside on anticlinal walls in darkness and move to periclinal or anticlinal walls under weak or strong light conditions, respectively. Here we reveal that red light-induced nuclear movement is mediated by neochrome1 (neo1), blue ligh...
متن کاملAdiantum capillus-veneris Linn. (Maidenhair fern) in modern phytotherapy
Background and objectives: Maidenhair fern is an herbal medicine belonging to the family Pteridaceae which is extensively found in Atlantic coast as far as Ireland, America and Iran. The fronds of Adiantum capillus-veneris are prescribed for treatment of different diseases. Different phytochemical compositions such as flavonoids, alkaloids, tannins, terpenoids, etc...
متن کاملThe fern Adiantum capillus-veneris lacks stomatal responses to blue light.
We investigated the responses of stomata to light in the fern Adiantum capillus-veneris, a typical species of Leptosporangiopsida. Stomata in the intact leaves of the sporophytes opened in response to red light, but they did not open when blue light was superimposed on the red light. The results were confirmed in the isolated Adiantum epidermis. The red light-induced stomatal response was not a...
