Abstract The marine diatoms Bellerochea yucatanensis and Thalassiosira rotula were grown at different salinities (20/25, 35, and 40/45‰ salinity (S), respectively) under normal air (0.035 vol.% CO2). No significant variations in the percentage of gross photosynthetic products (e.g. total amino acids, sugar phosphates) were found as a function of salinity during growth. The bulk of the soluble 14C-radioactivity was detected in amino acids. 14C-labelling of glutamine increased markedly with salinity. Low salt - grown algae are characterized by enhanced amino acid pools, mainly of aspartic acid, asparagine and glutamine. It was found that the tested amino acids are not involved in osmoregulation.

Seedlings of white pine (Pinus strobus L.) and detached shoots of white and loblolly (P. taeda L.) pines were exposed to various concentrations of ozone either before or during photosynthetic fixation of 14CO2. The major changes in distribution of 14C as a result of ozone treatment were (1) a reduction of relative activity in soluble sugars; (2) an increase in activity in sugar phosphates; and (3) an increase in activity in free amino acids, especially alanine. Significant differences in 14C fixation patterns were observed at ozone concentrations as low as 10 pphm (parts per hundred million), and during 14CO2 fixation times as short as 10 min. However, other combinations of treatment levels and times did not always result in statistically significant effects.
