“…Similar results were reported by Gusev et al (1987) for species of Ceramium, Laurencia, Gracilaria, Furcellaria and Phyllophora and also by Liu & Gordon (1987) for Pterocladiella capillacea. Other studies reported similar results for Porphyra umbilicalis (Liu & Kloareg, 1991), Grateloupia doryphora (Robaina et al, 1990), Eucheuma denticulatum (Dawes & Koch, 1991), Laurencia sp. (Robaina et al, 1992), Gracilaria verrucosa (Kaczyna & Megnet, 1993) and Solieria filiformis (Robledo & Garcia-Reina, 1993).…”

Micropropagation as a tool for sustainable utilization and conservation of populations of Rhodophyta. Micropropagation, or in vitro clonal propagation, allows the production of a large number of individuals within a short period. These micropropagated clones could be used as seedlings for seaweed cultivation, avoiding collection from natural beds. Consequently, there has been an increasing interest in micropropagation as a tool for preservation of populations of marine red algae on the Brazilian coast and for the sustainable production of raw material for commercial exploration. This paper reviews the literature on tissue culture and micropropagation of red algae published during the three last decades. Based on the literature, we can conclude that the regeneration process is complex and diversified in different species of Rhodophyta and that the success of micropropagation depends on this process. Species belonging to the orders Bangiales and Ceramiales showed low potential for regeneration, while Gigartinales species showed the highest potential for regeneration. Micropropagation of commercially important red algae is fundamental for the conservation of natural populations by providing seedlings for cultivation and for germplasm collections, both for the conservation of genetic diversity and for biotechnological applications.

“…According to Polne-Fuller & Gibor (1987) the development of this callus like structures both in presence and absence of plant growth regulators is due to the wound healing process in seaweeds. Plant growth regulators also promoted callus growth in Kappaphycus alvarezii (Dawes and Koch 1991;Dawes et al 1993). Sahoo and Singh (2006) studied thallus regeneration in Cystoseira indica.…”

“…Dawes and Koch (1991) and Dawes et al (1993) investigated the effect of plant growth regulators on callus development and regeneration process. Similarly, Hurtado and Cheney (2003) through tissue culture studies on Eucheuma denticulatum (Burman) Collins et Harvey generated the new strains.…”

“…Com o intuito de otimizar essa fase, alguns trabalhos foram realizados por Saga & Sakai (1983), Garcia-Reina et al (1987), Lawlor et al (1987) e Chen & McCracken (1993). Apesar dessa dificuldade, estudos sobre micropropagação, particularmente nas rodofíceas, foram realizados, mais recentemente, em vários locais do mundo, enfocando o crescimento, a indução de calos e a regeneração dos talos por Gusev et al (1987), PolneFuller & Gibor (1987), Bradley & Cheney (1991), Robaina et al (1990), Liu & Kloareg (1991), Dawes & Koch (1991), Kaczyma & Megnet (1993), Yokoya et al (1993Yokoya et al ( , 1999Yokoya et al ( , 2003, Yokoya & Handro (1996, Huang & Fujita (1997), Garcia-Jimenez et al (1998) e Yokoya (2000.…”

-(Callus growth and regeneration of apical segments of Hypnea musciformis (Wulfen) Lamouroux (Gigartinales, Rhodophyta): obtention of axenic cultures and agar concentration effects). Axenic cultures of Hypnea musciformis (Wulfen) Lamouroux were established in Provasoli (PES) solid medium with different agar concentrations (0.4%, 0.6%, 0.8% e 1.0%) to evaluate their effects on callus growth and plant regeneration. The cultures in solid medium induced the growth of four types of callus (apical -CApi, lateral 1 -CLat1, lateral 2 -CLat2, and basal -CBas), which consist of pigmented and unisseriate proliferations. The type CApi was the most frequent (rate of 5.3 calli per explant at 1.0% of agar). The highest biomass of regenerated plantlets (7.4 g) was obtained from calli cultured at 1.0% of agar. The growth of the four types of calli is reported for the first time, and indicates that different agar concentrations in the medium induce morphogenetic effects on callus growth and regeneration of apical segments in H. musciformis.Key words -agar effects, axenic culture, callus, Hypnea musciformis, Rhodophyta RESUMO -(Formação de calos e regeneração de segmentos apicais de Hypnea musciformis (Wulfen) Lamouroux (Gigartinales, Rhodophyta): obtenção de culturas axênicas e efeitos da concentração do ágar). Culturas axênicas de Hypnea musciformis (Wulfen) Lamouroux foram estabelecidas em meio de Provasoli (PES) sólido com diferentes concentrações de ágar (0,4%, 0,6%, 0,8% e 1,0%) para avaliar o seu efeito na formação de calos e na regeneração de plantas. O cultivo em meio sólido induziu a formação de quatro tipos de calos (apical -CApi, lateral 1 -CLat1, lateral 2 -CLat2 e basal -CBas), os quais são constituídos internamente por proliferações unisseriadas pigmentadas. O tipo CApi foi o mais freqüente (taxa de 5,3 calos por explante em 1,0% de ágar). A maior biomassa das plântulas regeneradas (7,4 g) foi alcançada a partir de calos cultivados a 1,0% de ágar. A formação dos quatro tipos de calos é um dado inédito e indica que as diferentes concentrações de ágar no meio apresentam efeitos morfogenéticos no crescimento dos calos e na regeneração de segmentos apicais em H. musciformis.
