Opposing action of photosystem II assembly factors RBD1 and HCF136 underlies light-regulated psbA translation in plant chloroplasts

Margarita Rojas, Rosalind E. Williams-Carrier, Prakitchai Chotewutmontri…·Alice Barkan

This study shows that RBD1 and HCF136 opposingly regulate psbA translation in response to light-induced D1 damage in chloroplasts.

Light activates psbA translation in plants by relieving inhibition of translation factor HCF173 by the psbA ORF in cis

Rosalind E. Williams-Carrier, Prakitchai Chotewutmontri, Sarah Perkel…·Alice Barkan

The paper shows that light activates psbA translation in plants by relieving repression from the psbA ORF, which is mediated by HCF173 and HCF244.

Translational activation by a synthetic PPR protein elucidates control of psbA translation in Arabidopsis chloroplasts

Margarita Rojas, Prakitchai Chotewutmontri, Alice Barkan

A synthetic PPR protein substitutes for HCF173, elucidating its role in activating psbA translation and demonstrating synthetic PPRs' ability to control chloroplast gene expression.
