Guanosine tetraphosphate (ppGpp) promotes tolerance to 2 excess light in Arabidopsis thaliana.

This study shows that ppGpp over-accumulation in Arabidopsis thaliana increases tolerance to excess light through physiological changes, not NPQ.

A Unique LHCE Light-Harvesting protein Family is involved in Photosystem I and II Far-Red Absorption in Euglena gracilis

This study identifies a unique Lhce light-harvesting complex in Euglena gracilis that dynamically associates with PSII and expands PSI light harvesting, revealing an alternative strategy for light acclimation in secondary plastids.

A high-light tolerant alga from the desert is protected from oxidative stress by NPQ-independent responses

This study identifies NPQ-independent mechanisms in Chlorella ohadii that protect against oxidative stress under high light.

Cyclic electron flow in Chlamydomonas reinhardtii

This study measures cyclic electron flow (CEF) in Chlamydomonas reinhardtii using spectroscopic methods, showing it operates at a constant rate regardless of oxygen concentration and revealing inconsistencies in proposed CEF pathways.

Photosynthesis is heavily chlororespiration-sensitive under fluctuating light conditions

This study shows that chlororespiration, via PTOX2, is critical for maintaining chloroplast redox balance during light transitions in Chlamydomonas reinhardtii.
