Fatty acid desaturases are enzymes that introduce double bonds into the hydrocarbon chains of fatty acids. The fatty acid desaturases from 37 cyanobacterial genomes were identified and classified based upon their conserved histidine-rich motifs and phylogenetic analysis, which help to determine the amounts and distributions of desaturases in cyanobacterial(More)
In 2008, a massive Ulva prolifera bloom, with a 3-million-ton biomass covering an area of 1.29 × 10(4) km(2) at its largest, suddenly appeared from May to July in South Yellow Sea. The mechanism behind the rapid growth of these seaweeds was investigated. Molecular phylogenetic analysis of free-floating algal samples from the Yellow Sea suggested that U.(More)
In this study, a cDNA encoding a novel acyl-CoA:diacylglycerol acyltransferase (DGAT)-like protein is identified and isolated from the diatom microalga Phaeodactylum tricornutum (PtDGAT3). Analysis of the sequence reveals that ptDGAT3 cDNA encodes a protein of 504 amino acids with a molecular mass of 64.5 KDa. The putative ptDGAT3 protein has two catalytic(More)
Solar radiation absorbed by marine phytoplankton can follow three possible paths. By simultaneously measuring the quantum yields of photochemistry and chlorophyll fluorescence in situ, we calculate that, on average, ~60% of absorbed photons are converted to heat, only 35% are directed toward photochemical water splitting, and the rest are reemitted as(More)
Seaweed genetic engineering is a transgenic expression system with unique features compared with those of heterotrophic prokaryotes and higher plants. This study discusses several newly sequenced seaweed nuclear genomes and the necessity that research on vector design should consider endogenous promoters, codon optimization, and gene copy number. Seaweed(More)
Coastal biotechnology is developing fast with exciting achievements being realized in biological, chemical, and environmental sciences and technologies. The aim of the 1st International Conference on Coastal Biotechnology (1st ICCB) on " Coastal Biotechnology for Sustainable Development , " which was successfully held in the Australian winter of 2012 in(More)
