High impact information on Algae, Green

• The binding of cytochrome c6 to PSI in green algae involves interaction of a negative patch with a positive domain of PSI [4].
• We infer that the common ancestor of green algae and land plants harbored a tightly packed, gene-rich, and relatively intron-poor mitochondrial genome [5].
• The group II introns in this ancestral genome appear to have spread to new mtDNA sites during the evolution of bryophytes and charalean green algae, accounting for part of the intron diversity found in Chara and land plant mitochondria [5].
• Three of the Nephroselmis genes (nad10, rpl14, and rnpB) have not been identified in previously sequenced mtDNAs of green algae and land plants [6].

• The results indicated that: (1) the decreasing order of the average acute toxicity to cyanobacteria and green algae of five dissimilar organotins and pyrethroids pesticides was: fentin hydroxide > cyhexatin > azocyclotin > fenbutatin oxide > beta-cyfluthrin [10].
• Also, five pure cultures isolated from various sites (two unicellular green algae and three dinitrogen-fixing cyanobacteria) were tested for their ability to metabolise DDT [11].
• This study analyzed the toxicity of three pesticides (the herbicide atrazine, the insecticide chlorpyrifos and the fungicide chlorothalonil) individually, and in two mixtures (atrazine and chlorpyrifos; atrazine and chlorothalonil) to the marine phytoplankton species Dunaliella tertiolecta (Chlorophyta) [12].

Biological context of Algae, Green

• The availability of cells transformed with a CO2-regulated reporter gene should facilitate further studies on the metabolic adaptations that occur in some green algae in response to the external CO2 level [13].
• Molecular genetics of xanthophyll-dependent photoprotection in green algae and plants [14].
• They are found in prokaryotes and in red and green algae, where they provide electrons at low potentials for the reduction of nitrogen by nitrogenase, for the light-dependent reduction of NADP+ in photosynthesis, and for the reduction of sulfite [15].
• Results are presented showing the sorption of Cr(VI) from solutions by biomass of filamentous algae Spirogyra species [16].
• Genetic polymorphism in eight Chilean strains of the carotenogenic microalga Dunaliella salina Teodoresco (Chlorophyta) [17].

Anatomical context of Algae, Green

• The chloroplast genome of chromophytic and rhodophytic algae differs from the plastid genome of plants and green algae in that it encodes the gene for the small subunit (rbcS) of ribulose 1,5-bisphosphate carboxylase/oxygenase [18].
• The results presented here show that this is a general property of D1 as it can be demonstrated in thylakoids of cyanophytes, Dasicladaceae, green algae, and C3 and C4 plants [19].
• We report that green algae and human centrin delay cleavage and promote the formation of abnormal blastomeres in which the distribution of microtubule asters and of nuclei is dramatically impaired [20].
• Lobomonas piriformis is a member of an order of green algae (Volvocales) that have crystalline glycoprotein cell walls [21].
• The cytoplasm (with its organelles) of intact cells of Ernodesmis verticillata (Chlorophyta) can be induced to contract in the presence of calcium ionophores and phenothiazine antipsychotics [22].

Associations of Algae, Green with chemical compounds

• The central photochemical reaction in photosystem II of green algae and plants and the reaction center of some photosynthetic bacteria involves a one-electron transfer from a light-activated chlorin complex to a bound quinone molecule [23].
• Unlike higher plants and green algae, the genes encoding the large and the small subunits of ribulose-1,5-bisphosphate carboxylase/oxygenase are chloroplast-encoded and closely associated (Hwang and Tabita, 1989) [24].
• Earlier work using mutants and heterologous expression has shown that a high-affinity nitrate transport system from the unicellular green algae, Chlamydomonas reinhardtii required two gene products for function [25].
• We provide evidence that ammonium, nitrate, and light regulate GS transcript accumulation in green algae [26].
• Purification and characterization of pentagalloylglucose, and alpha-glucosidase inhibitor/antibiotic from the freshwater green alga Spirogyra varians [27].

Gene context of Algae, Green

• Here we report that centrins from yeast, green algae, and humans bound with high affinity to a peptide of the yeast centrosomal component Kar1p [28].
• These experiments along with sequence analysis disclosed the presence, in both green algae, of a single IA1 intron in the psaB gene and of two group I introns (IA2 and IA1) in the psbC gene [29].
• The C. paradoxa petF gene predicts a protein of 99 amino acids (aa) which is more similar to type-I ferredoxins of diverse cyanobacteria than to those of green algae, dinoflagellates, and higher plants [30].
• The chlL gene product is involved in the light-independent synthesis of chlorophyll in photosynthetic bacteria, green algae and non-flowering plants [31].
• In this study we compared sequences of the rbcL (Rubisco large subunit-encoding) genes of pyrenoid-less Chloromonas species with those of closely related pyrenoid-containing Chlamydomonas species in the "Chloromonas lineage" and with those of 45 other green algae [32].
