Plastid gene expression derived signaling
Treatment of plants with inhibitors of chloroplast translation represses expression levels of certain nuclear-encoded proteins indicating that plastid protein synthesis generates a signal that is a prerequisite for the expression of a subset of nuclear genes. However, how inhibition of the synthesis of plastid-encoded proteins releases plastid-derived signals to the cytoplasm/nucleus and which genes are target of these transmitted signals remain open questions with pivotal significance for our understanding of plastid-nucleus-interactions.
