| gfp-like chromoproteins as a source of far-red fluorescent proteins. | we have employed a new approach to generate novel fluorescent proteins (fps) from red absorbing chromoproteins. an identical single amino acid substitution converted novel chromoproteins from the species anthozoa (heteractis crispa, condylactis gigantea, and goniopora tenuidens) into far-red fps (emission lambda(max)=615-640 nm). moreover, coupled site-directed and random mutagenesis of the chromoprotein from h. crispa resulted in a unique far-red fp (hcred) that exhibited bright emission at 645 ... | 2001 | 11682051 |
| a purple-blue chromoprotein from goniopora tenuidens belongs to the dsred subfamily of gfp-like proteins. | a number of recently cloned chromoproteins homologous to the green fluorescent protein show a substantial bathochromic shift in absorption spectra. compared with red fluorescent protein from discosoma sp. (dsred), mutants of these so-called far-red proteins exhibit a clear red shift in emission spectra as well. here we report that a far-red chromoprotein from goniopora tenuidens (gtcp) contains a chromophore of the same chemical structure as dsred. denaturation kinetics of both dsred and gtcp un ... | 2003 | 12975373 |
| toxic exudate from the hard coral goniopora tenuidens. | ten colonies of goniopora tenuidens were placed individually in sea water for 1 hr after which time the sea water was assayed using toxicity to another hard coral galaxea fascicularis and to other colonies of g. tenuidens. sea water from eight of the 10 colonies assayed was toxic to at least one of the bioassay organisms. thus, g. tenuidens can extrude biologically active substances that adversely affect potential competitors, both interspecific and conspecific. | 1990 | 1982375 |
| highly organized structure in the non-coding region of the psba minicircle from clade c symbiodinium. | the chloroplast genes of dinoflagellates are distributed among small, circular dsdna molecules termed minicircles. in this paper, we describe the structure of the non-coding region of the psba minicircle from symbiodinium: dna sequence was obtained from five symbiodinium strains obtained from four different coral host species (goniopora tenuidens, heliofungia actiniformis, leptastrea purpurea and pocillopora damicornis), which had previously been determined to be closely related using lsu rdna r ... | 2003 | 14657100 |
| larvotoxic extracts of the hard coral goniopora tenuidens: allelochemicals that limit settlement of potential competitors? | aqueous extracts of goniopora tenuidens inhibited larval metamorphosis and post-metamorphic growth of the hard coral pocillopora damicornis. the extracts killed swimming larvae of four scleractinian corals and modified the behaviour of larvae of p. damicornis at concentrations as low as 3.9 micrograms ml-1. this toxicity may indicate the presence of allelochemicals that limit the settlement of potential competitors. | 1996 | 8730929 |
