“…The effect has been described independently of the possible involvement of photoreceptors on pigment synthesis. Such involvement has been proposed in red algae (Lopez-Figueroa & Niell 1989, Lopez-Figueroa et al 1989b) and a phytochrome-like protein has even been detected in Corallina elongata using monoclonal antibodies (Lopez-Figueroa et al 1989a). Nevertheless, the identification of these photoreceptors is still not established.…”

Effects of interactions between light quality and irradiance level were tested on photosynthetic pigments of the red intertidal alga Corallina elongata EUis et Soland. During a short-tern~ accommodation process (0 to 5 h), pigments adapted chromatically to light quality. R-phycoerythrin and R-phycocyanin increases were induced under green light at 180 pm01 m-2 S-' In contrast, chlorophyll a increased only under red light at the same irradiance level. In a n energy-limited situation, at a n irradiance (20 pm01 m-2 S-') close to the photosynthetic compensation point of C. elongata, the accommodation process was inhibited and no chromatic response was detected. The use of antibiotics (rifamycin and chlorarnphenicol) that inhibit chloroplastic protein synthesis revealed that red light acts on phycobiliprotein synthesis in the same way as antibiotics that suppress transcription and translation. The short-term accommodation process involves ' d e novo' synthesis of phycobiliproteins The rnechanism ot pigment accommodation is discussed in the frame of chromatic adaptation theory

“…Early work on this species examined photosynthetic performances (Häder et al, 1996(Häder et al, , 1997, synthesis of chlorophylls and phycobiliproteins in response to light composition (López-Figueroa et al, 1989;López-Figueroa and Niell, 1990) and effects of red and blue light on the N-metabolism (Figueroa, 1993). Estimates of productivity and calcification rates were provided by El Haikali et al (2004) for French populations.…”

“…So it is clear that the higher photosynthetic activity in red light, compared with blue light, might result from the greater amounts of pigments absorbing red photons. Indeed, cells grown in red light had more Chl a (Table 5 ) and the amount of PCBs, i.e., chromophores of APC, could also be significant as their synthesis depends on the PC content (Lemasson et al 1973 ; López-Figueroa et al 1989 ). As for blue light, it might be speculated that the decrease in the rate of photosynthesis was due to its reduced accessibility to Chl a because the amount of carotenoids was comparable with the content of Chl a (Table 5 ).…”

“…The difficulties arise, however, when the content of the individual pigment is dependent not only on light quality during cultivation but also on the duration of the measurement. López-Figueroa et al ( 1989 ) showed in red macroalga Corallina elongata that even short-term (30 min) illumination with red light ( λ max = 630 nm) greatly enhanced the synthesis of Chl a , PC, and APC, but not PE. In addition, Ojit et al ( 2015 ) reported that the production of APC in cyanobacterium Anabaena corcinalis cultured under red light was three times higher than under blue light.…”

Photosynthesis of the Cyanidioschyzon merolae cells in blue, red, and white light

Photosynthesis and respiration rates, pigment contents, CO2 compensation point, and carbonic anhydrase activity in Cyanidioschizon merolae cultivated in blue, red, and white light were measured. At the same light quality as during the growth, the photosynthesis of cells in blue light was significantly lowered, while under red light only slightly decreased as compared with white control. In white light, the quality of light during growth had no effect on the rate of photosynthesis at low O2 and high CO2 concentration, whereas their atmospheric level caused only slight decrease. Blue light reduced markedly photosynthesis rate of cells grown in white and red light, whereas the effect of red light was not so great. Only cells grown in the blue light showed increased respiration rate following the period of both the darkness and illumination. Cells grown in red light had the greatest amount of chlorophyll a, zeaxanthin, and β-carotene, while those in blue light had more phycocyanin. The dependence on O2 concentration of the CO2 compensation point and the rate of photosynthesis indicate that this alga possessed photorespiration. Differences in the rate of photosynthesis at different light qualities are discussed in relation to the content of pigments and transferred light energy together with the possible influence of related processes. Our data showed that blue and red light regulate photosynthesis in C. merolae for adjusting its metabolism to unfavorable for photosynthesis light conditions.
