“…In contrast, the seawater temperature at Shimoda is as high as around 25°C in summer (Sakanishi et al 1989); consequently, the photosynthetic activity of E. cava collected from Shimoda decreased when the temperature was increased to 30°C. In relation to the expression of photosynthesis-related proteins at high temperature, it is known in seaweeds that the optimum temperature for photosynthesis is generally higher than the environmental temperature under comfortable light condition and is different between individuals with different growing temperature (Hata and Yokohama 1976;Serisawa et al 2001;Yokohama 1973). The seawater temperature at Shimoda is as high as around 25°C in summer; consequently, the photosynthetic activity of E. cava collected from Shimoda decreased when the temperature was increased to 30°C (Sakanishi et al 1989).…”

Proteomic profiling on Ecklonia cava Kjellman grown under various seawater temperatures was conducted to search for biomarkers that were useful to evaluate the health of the colonies and formulate actions for the maintenance of marine forests. In the cultivated strains, protein expression was not significantly changed when the cultivation temperature was lowered from 15°C (control) to 10°C. On the contrary, it was markedly changed, i.e., photosynthesis-related proteins were up-regulated and metabolic enzymes were down-regulated, when the temperature was heightened to 20°C. With the cultivation at 30°C, 25 spots within 27 spots expressed at this temperature peculiarly could be identified and classified into ten proteins. Of the distinctive 27 spots at 30°C, 20 spots were detected in the wild strains cultured at the same temperature for a brief time. It is presumed that the proteins including vanadium-dependent bromoperoxidase are heat stressinduced proteins.

“…Explants used in this experiment were approximately 1016 ±0.009 mg wet weight (mg ww ; ±standard deviation) and were acclimated overnight with sterilized seawater in the incubator (Muraoka et al 1998;Serisawa et al 2001). To start the experiment, we randomly selected at least five explants and placed them in 100 mL BOD bottles containing sterilized natural seawater.…”

The effect of irradiance and temperature on the photosynthesis and growth of a Vietnamese-cultivated red alga, Kappaphycus alvarezii, was determined by laboratory and field measurements. Dissolved oxygen sensors and pulse amplitude modulated (PAM) fluorometry were used for the measurements of photosynthetic efficiency. A Diving-PAM revealed that in situ measurements of the effective quantum yield (Φ PSII ) were negatively correlated with incident irradiance. Φ PSII decreased as irradiance increased at noon and recovered in the evening, suggesting photo-inhibition. A model of the net photosynthesis-irradiance (P-E) relationship determined in a laboratory experiment at 26°C revealed that the net photosynthetic rate quickly increased at irradiances below the estimated saturation irradiance of 154 μmol photons m −2 s −1 (95 % Bayesian credible interval (BCI) of 117-203 μmol photons m −2 s −1 ). Gross photosynthesis and dark respiration under the laboratory measurements were also determined over a range of temperatures (8-42°C), revealing that the gross photosynthetic rates of 8.0 (BCI 7.03-9.59) μg O 2 g ww −1 min −1 at 31.1 (BCI 30.2-32.0)°C, and the dark respiration rate increased exponentially from a low of 0.22 μg O 2 g ww −1 min −1 at 10°C to a high of 1.88 μg O 2 g ww −1 min −1 at 42°C. The estimated highest value of the maximum quantum yield (Φ PSII at 0 μmol photons m −2 s −1 = F v /F m ) determined with the Imaging-PAM and occurred at 22.2 (BCI 20.8-23.5)°C and was 0.51 (BCI 0.48-0.54).Relative growth rate (RGR) and the survival rate after 2 weeks of laboratory culture showed that the relatively high growth rates (ca. 1.5 %) occurred at 28 and 32°C; however, mortality was 100 % at 36°C. This species is considered to be well-adapted to the natural temperature range of study site; however, it is likely close to the marginal temperature conditions. Furthermore, daytime incident irradiance on the frond under fine clear sky might be too strong for the effective photosynthesis of this species, suggesting that optimum irradiance for gross photosynthesis with the minimum decline of Φ PSII seems to be much lower.
