The 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...
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 کاملComplete nucleotide sequence of the chloroplast genome from a leptosporangiate fern, Adiantum capillus-veneris L.
We determined the complete nucleotide sequence of the chloroplast genome of the leptosporangiate fern, Adiantum capillus-veneris L. (Pteridaceae). The circular genome is 150,568 bp, with a large single-copy region (LSC) of 82,282 bp, a small-single copy region (SSC) of 21,392 bp and inverted repeats (IR) of 23,447 bp each. We compared the sequence to other published chloroplast genomes to infer...
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...
