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

Shanna Romand, Chen Hu, Aurélie Crepin…·Ben Field

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

Madhu Tiwari, Brigitte Ksas, Bertrand Légeret…·Michel Havaux

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