High impact information on Dryopteris

• The effect of pH on the (1)H NMR spectrum, reduction potential, and self-exchange rate constant of the novel plastocyanin (PCu) from the fern plant Dryopteris crassirhizoma has been studied [1].
• L-methionine decarboxylase from Dryopteris filix-mas: purification, characterization, substrate specificity, abortive transamination of the coenzyme, and stereochemical courses of substrate decarboxylation and coenzyme transamination [2].
• Phloroglucinol derivatives of eleven Dryopteris species from Japan [3].
• Three new kaempferol glycosides, called crassirhizomosides A (1), B (2) and C (3), were isolated from the rhizome of Dryopteris crassirhizoma (Aspidiaceae), together with the known kaempferol glycoside, sutchuenoside A (4) [4].
• CONCLUSION: Compound 1 is a new one, the others were isolated from Dryopteris for the first time [5].

Biological context of Dryopteris

• L-Methionine decarboxylase from Dryopteris filix-mas catalyzes the decarboxylation of L-methionine and a range of straight- and branched-chain L-amino acids to give the corresponding amine products [6].

Anatomical context of Dryopteris

• Luminal chloroplast connections with endoplasmic reticulum-like cisterns and cell wall in Dryopteris filix-mas gametophytes [7].

Associations of Dryopteris with chemical compounds

• L-Methionine decarboxylase from the male fern Dryopteris filix-mas has been purified 256-fold from acetone powder extracts to very near homogeneity [2].
• METHODS: Fresh plant of Dryopteris sublaeta ching et hsu was extracted twice with boiling water, concentrated to small volume under reduced pressure at 50 degrees C. The concentrated material was partitioned with ether, ethyl acetate, and n-butanol [8].
• A new stilbene glycoside from Dryopteris sublaeta [8].
• The distribution pattern of total lipids, glyco- and phospholipids, and one betaine lipid (DGTS) in the fronds ofthe ferns Dryopteris filix-mas and Matteuccia struthiopteris was studied [9].

Gene context of Dryopteris

• Evidence for the association of acyl transferases with the production of nuclear evaginations in maturing eggs of the fern Dryopteris filix-mas [10].
