Plastid retrograde signaling: A developmental perspective.

ABSTRACT: Chloroplast activities influence nuclear gene expression, a phenomenon referred to as retrograde signaling. Biogenic retrograde signals have been revealed by changes in nuclear gene expression when chloroplast development is disrupted. Research on biogenic signaling has focused on repression of Photosynthesis-Associated Nuclear Genes (PhANGs), but this is just one component of a syndrome involving altered expression of thousands of genes involved in diverse processes, many of which are upregulated. We discuss evidence for a framework that accounts for most of this syndrome. Disruption of chloroplast biogenesis prevents the production of signals required to progress through discrete steps in the program of photosynthetic differentiation, causing retention of juvenile states. As a result, ex
