High impact information on Acetabularia

• Temperature dependence of cycloheximide-sensitive phase of circadian cycle in Acetabularia mediterranea [1].
• Temperature is known to influence the function of the circadian regulatory system in Acetabularia, but the effect on frequency is small (Q10 approximately equal to 0.8) due to the existence of a temperature-compensating feature [1].
• The midpoint potential for Acetabularia kinase activity in the dark is 120 +/- 10 mV and is compatible with the involvement of plastoquinone in the kinase activation via reduction of the cytochrome complex [2].
• The occurrence of an enzyme that catalyses the conversion of cytidine into deoxycytidine was demonstrated in homogenates of Acetabularia [3].
• This hypothesis prompted experiments aimed at defining the site of translation of thymidylate kinase in a species closely related to Acetabularia but long ago separated from it: Batophora oerstedii [4].

Biological context of Acetabularia

• Evidence for a cycloheximide-sensitive component in the biological clock of Acetabularia [5].
• Southern analysis suggests that several other kn1-like homeobox genes exist in the Acetabularia genome [6].
• Amino acid sequences of the small subunit of ribulose-1,5-bisphosphate carboxylase (SSU) of Acetabularia cliftonii and A. mediterranea were derived from five cDNA sequences of each of the two species of algae and by direct amino acid sequence determination of the isolated protein [7].
• Nucleo-cytoplasmic interactions in the regulation of thymidine phosphorylation in Acetabularia [8].
• Circadian rhythm of polysaccharide synthesis in Acetabularia [9].

Anatomical context of Acetabularia

• The giant unicellular green alga Acetabularia was labeled with the lipophilic fluorochrome DiOC6 (3,3'-dihexyloxacarbocyanine) and examined by confocal laser scanning microscopy to study the distribution of the endoplasmic reticulum (ER) and its dynamic changes after the application of inhibitors [10].
• Effects of isoflurane on measurements of delayed lumininescence in Acetabularia acetabulum [11].

Associations of Acetabularia with chemical compounds

• Regulation of UDPG pyrophosphorylase in Acetabularia mediterranea [12].
• Strong homology between the small subunit of ribulose-1,5-bisphosphate carboxylase/oxygenase of two species of Acetabularia and the occurrence of unusual codon usage [7].
• Isolation and characterization of different forms of thioredoxins from the green alga Acetabularia mediterranea: identification of an NADP/thioredoxin system in the extrachloroplastic fraction [13].
• We have used isoflurane in a unicellular alga, Acetabularia acetabulum, to test the dynamics of choloroplast organization [11].
• Poly(A)+ RNA during vegetative development of Acetabularia peniculus [14].

Gene context of Acetabularia

• The function of the translation product of cDNA for Acetabularia vacuolar H(+)-pyrophosphatase was examined using the Saccharomyces cerevisiae VMA3-deficient strain [15].
• Thymidylate kinase from Acetabularia. I. Properties of the enzyme [16].
• The occurrence of a dCMP deaminase in Acetabularia mediterranea has been demonstrated [17].
• A procedure has been developed for the simultaneous purification to apparent homogeneity of chloroplast thioredoxins f and m, and nonchloroplast thioredoxin h, from the green alga Acetabularia mediterranea [13].
• Isolated chloroplasts of Acetabularia incorporate radioactive amino acids into more than 30 polypeptides in the light, including the apoprotein of the P700-chlorophyll a protein complex, the reaction centre core of photosystem I [Biochim. Biophys. Acta, 609. 107-120 (1980)] [18].
