The present study describes the isolation of pigmentation mutants of Porphyra yezoensis Ueda induced by heavy-ion beam irradiation for the first time. The gametophytic blades were irradiated with 12 C +6 ion beams within a dose range of 25-400 Gy. From the survival rate and cell growth of the irradiated blades, it is suggested that a dose of 150 Gy or less is suitable to induce mutation for the isolation of mutants of P. yezoensis. After irradiation, red, green and deep reddish brown-colored gametophytic blades developed from archeospores that were released from each of the mutated cell clusters of the respective different colors, and the red mutant strain (IBY-R1) and green mutant strain (IBY-G1) were established as a conchocelis colony in culture. Blades of the mutants were characterized by their growth and photosynthetic pigment contents compared with those of the wild-type. From these results, it is clear that heavy-ion beam mutagenesis will be an effective tool for genetic and breeding studies of Porphyra, and also for other algal research.

“…However, there are conflicts between the identifications of various types of pigments in identical species of algae (Kikuchi et al, 1979;Zeng et al, 1984), as well as for criteria of biliprotein purity (Gantt, 1981;Glazer & Hixon, 1975;Glazer et al, 1982). Phycobiliproteins have been purified using various methods including ion exchange chromatographies, reverse phase partition chromatography, gel filtration, preparative electrophoresis and even gradient centrifugation (Swanson & Galzer, 1990).…”

Gel-filtration-purified R-phycoerythrin and phycocyanin from the filamentous phase of Bangia atropurpurea were subjected to high performance anion exchange chromatographic separation. The purified R-phycoerythrin was a mixture of three charged-isomers that were well resolved in a Bio-Gel MA7P column by elution with a NaCl gradient in phosphate buffer. These were tentatively called phycoerythrin charged-isomers and were also separable from phycocyanin and allophycocyanin by the same system. Hence, it is suggested that the ion exchange chromatographic and the sample preparation methods presented in this report can be used to distinguish the various natures of biliproteins in red algae in addition to the polyacrylamide gel electrophoresis technique. Isomers of R-phycoerythrin have the same absorption and emission spectra and were studied for their subunit compositions by a PRP-3 reverse phase column chromatography. All three charged-isomers have the same a and /B subunits in common but differ in their y subunit.

“…Photosynthetic accessory pigments of phycobiliproteins have been extensively studied in the blue-green alga and in some species of the red alga (O'hEocha, 1965). However, there are conflicts between the identifications of various types of pigments in identical species of algae (Kikuchi et al, 1979;Zeng et al, 1984), as well as for criteria of biliprotein purity (Gantt, 1981;Glazer & Hixon, 1975;Glazer et al, 1982).
