A phosphorylation-deficient ribosomal protein eS6 is largely functional in Arabidopsis thaliana, rescuing mutant defects from global translation and gene expression to photosynthesis and growth

This study shows that a phosphorylation-deficient eS6 isoform in Arabidopsis thaliana largely rescues mutant defects in growth, photosynthesis, and gene expression, with minor residual issues.

Light activates the translational regulatory GCN2 kinase via reactive oxygen species emanating from the chloroplast

The paper shows light-induced reactive oxygen species activate the GCN2 kinase in Arabidopsis, leading to eIF2 phosphorylation and affecting cytosolic translation.
