The microbiota of four individual deep water sponges, Lissodendoryx diversichela, Poecillastra compressa, Inflatella pellicula, and Stelletta normani, together with surrounding seawater were analysed by pyrosequencing of a region of the 16S rRNA gene common to Bacteria and Archaea. Due to sampling constraints at depths below 700 m duplicate samples were not collected. The microbial communities ...

In order to find a way to induce rooting on cuttings of Hemarthria compressa cv. Ya'an under controlled conditions, a project was carried out to study the effect of naphthalene acetic acid (NAA) on rooting in stem cuttings and related physiological changes during the rooting process of Hemarthria compressa. The cuttings were treated with five concentrations of NAA (0, 100, 200 300, 400 mg/l) at...

Luteimonas sp. strain JM171 was cultivated from mucus collected around the coral Porites lobata The JM171 draft genome of 2,992,353 bp contains 2,672 protein-coding open reading frames, 45 tRNA coding regions, and encodes a putative globin-coupled diguanylate cyclase, JmGReg.

To test the hypothesis that ammonium uptake by coral reefs is mass-transfer limited and to determine the relative effects of water velocity and community roughness on uptake, we measured the rates of ammonium uptake by reefs at velocities ranging from 3.3 to 37.5 cm sI. Two assemblages of coral rubble (relatively rough and relatively smooth) and two assemblages of live coral (Porites compressa ...

Annual density banding provided growth characteristics for 245 similar-sized, massive colonies of Porites from similar locations on 29 reefs from across the length and breadth of the Great Barrier Reef (GBR), Australia. Values obtained were density, extension rate, and calcification rate. Tissue thickness, the depth to which skeletons were occupied by tissue at the time of collection, was also ...

The causative agent of the Indo-Pacific coral disease, Porites ulcerative white spot syndrome (PUWS), that affects Porites spp. and a few other coral genera has so far remained unidentified. Inoculation of thiosulphate citrate bile sucrose (TCBS) agar with tissue material from Porites cylindrica infected with white spot produced colonies of approximately 3 mm diameter consisting of Gram-negativ...
