Analysis of Phycodnaviridae Tetrapyrrole Enzymes: Subcellular Localization and Functional Divergence from Host Homologs

The paper analyzes Phycodnaviridae viral homologs of heme oxygenase-1 and Phycocyanobilin:Ferredoxin oxidoreductase to predict their subcellular localization and functional divergence from host enzymes.

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 cytochrome P450 involved in apocarotenoid signaling enhances plant photosynthetic capacity and photooxidative stress tolerance

This study identifies CYP81D11 as a cytochrome P450 that enhances photosynthetic capacity and photooxidative stress tolerance in Arabidopsis through apocarotenoid signaling.

Acclimation of photosynthesis began with a Cu-binding superoxide detoxifying enzyme

The paper identifies APE1 as a Cu-binding superoxide detoxifying enzyme essential for photosynthetic acclimation to oxygenic environments.
