Abstract:
Filaments were induced from cut edges of segments of Gloiosiphonia capillaris, Gloiopeltis furcata, Chondrus ocellatus, Solieria tenuis, Ceramium kondoi, Chondria tenuissima, Laurencia okamurai and from the intact surfaces of Ceramium kondoi and Chondria tenuissima under unialgal culture conditions. The filaments of Gloiosiphonia capillaris can grow vegetatively under free-living conditions, while filaments of Gloiopeltis furcata tended to differentiate after excision from explants and grew autotrophically to the 10- to 20-cell stage. Filaments of other species usually survived attached to generating explants. Two distinct modes of filament regeneration were discerned among the species. In Gloiosiphonia capillaris, Gloiopeltis furcata, Chondrus ocellatus and Solieria tenuis, filaments initially developed into crust or crust-like compact tissue in suspension culture; upright thalli developed from the crusts. In Ceramium kondoi, Chondria tenuissima and Laurencia okamurai, thalli were generated from pseudoparenchyma that was developed from filaments, while creeping parts (rhizoids) formed a prostrate system.
