Novel insights on the contribution of plastoglobules and reactive oxygen species to chromoplast differentiation

The paper shows that inducing phytoene synthase in leaf chloroplasts leads to chromoplast differentiation, with plastoglobules accumulating carotenoids and other isoprenoids, and that reactive oxygen species promote this process.

Chloroplast protein import determines plant proteostasis and retrograde signaling

This study shows that chloroplast protein import and proteases regulate polyQ proteostasis in plants, with implications for human disease therapy.

The intrinsic chaperone network of Arabidopsis stem cells confers protection against proteotoxic stress

This study identifies enhanced proteostasis mechanisms in Arabidopsis root stem cells that protect against proteotoxic stress by maintaining protein homeostasis through high levels of TRiC/CCT chaperones.

Synthetic biogenesis of chromoplasts from leaf chloroplasts

This study shows that artificially increasing phytoene production in chloroplasts triggers chromoplast differentiation in leaves, requiring reduced photosynthesis and increased carotenoid synthesis.
