Disease relevance of Adiantum

7. From these characteristics, CP2/PCB can be attributed to the Pr" photochemical type with gamma1 < or = 0.05, which comprises the minor phyA fraction (phyA"), phyB, Adiantum phy1 and Synechocystis Cph1 in contrast to the major phyA' fraction (Pr' type with gamma1 = 0.5) [1].

High impact information on Adiantum

The fern Adiantum capillus-veneris has an unconventional photoreceptor, phytochrome 3 (phy3), which is a chimaera of the red/far-red light receptor phytochrome and phototropin [2].
Here, we report the isolation of two blue light photoreceptor genes, designated cryptochrome genes 4 and 5 (CRY4 and CRY5), from the fern Adiantum capillus-veneris [3].
Reactive cysteine is protonated in the triplet excited state of the LOV2 domain in Adiantum phytochrome3 [4].
Part of the large subunit of the ribulose-1,5-bisphosphate carboxylase/oxygenase (rubisco) gene (rbcL) was sequenced from three fern species: Adiantum capillus-veneris, Botrypus strictus, and Osmunda cinnamomea var. fokiensis [5].
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 [6].

Biological context of Adiantum

Cryptochrome nucleocytoplasmic distribution and gene expression are regulated by light quality in the fern Adiantum capillus-veneris [3].

Associations of Adiantum with chemical compounds

Photoreaction of the cysteine S-H group in the LOV2 domain of Adiantum phytochrome3 [7].
Normethyl pentacyclic and lanostane-type triterpenes from Adiantum venustum [8].
A new triterpenoid from the fern Adiantum lunulatum and evaluation of antibacterial activity [9].

Analytical, diagnostic and therapeutic context of Adiantum

In this study, we compared light-induced structural changes of the LOV1 and LOV2 domains of a phototropin, Adiantum phytochrome3 (phy3), by means of UV-visible and Fourier transform infrared (FTIR) spectroscopy [10].
