Photosynthetic acclimation of higher plants to growth in fluctuating light environments.

This paper describes a study into the potential of plants to acclimate to light environments that fluctuate over time periods between 15 min and 3 h. Plants of Arabidopsis thaliana (L.) Heynh., Digitalis purpurea L. and Silene dioica (L.) Clairv. were grown at an irradiance 100 mumol m(-2) s(-1). After 4-6 weeks, they were transferred to light regimes that fluctuated between 100 and either 475 or 810 mumol m(-2) s(-1), in a regular cycle, for 7 days. Plants were shown, in most cases, to be able to undergo photosynthetic acclimation under such conditions, increasing maximum photosynthetic rate. The extent of acclimation varied between species. A more detailed study with S. dioica showed that this acclimation involved changes in both Rubisco protein and cytochrome f content, with only marginal changes in pigment content and composition. Acclimation to fluctuating light, at the protein level, did not fully reflect the acclimation to continuous high light - Rubisco protein increased more than would be expected from the mean irradiance, but less than expected from the high irradiance; cytochrome f increased when neither the mean nor the high irradiance would be expected to induce an increase.[1]
