Cover Image

It is widely known that photosynthetic organisms redistribute excessive energy through state transition (ST) mechanism by the movement of light harvesting complexes II (LHCII). However, in situ visualizations of the ST in the single-cell level under room temperature remain limited. Using newly developed noninvasive excitation spectral imaging, Zhang et al observed unicellular green algae called Chlamydomonas reinhardtii under ST induction. The home-built excitation spectral microscope provided powerful spectral information about excitation-energy transfer between Chl-a and Chl-b. The technique is sensitive to the Chl-b spectral component specifically bound to LHCII at a small spatial scale. Zhang et al discovered an ST-driven reversible rearrangement of Chl fluorescence.

The cover image shows reconstructed Whole, Chl-b, Chl-a, and Chl-b/Whole ratio images by using excitation spectra during ST induction. A live Chlamydomonas cell is inducted to state 1 (Bottom plane), state 2 (Middle plane), and again state 1 (Top plane) by using illumination with different colors. Red and the light blue arrow are indicated as 710 and 469 nm light respectively.

Cover Image

Pictured is a section of the optical setup of a high-speed excitation-spectral microscope (ESM). XianJun Zhang et al. used an ESM and high-resolution 3D microscopy to characterize state transition, a regulatory mechanism used by photosynthetic organisms, in the thylakoid membrane of wild-type and mutant strains of Chlamydomonas. The authors found that the thylakoid membrane undergoes fine-scale structural deformations during photosynthesis that were partially irreversible and showed site-dependent differences in state transition efficiency. The results provide insight into the molecular mechanisms underlying photosynthesis in green algae.
