Article Synopsis
  • The chloroplast proteome consists of proteins encoded by both the plastid and nuclear genomes, and its stability relies on a balance between protein synthesis and degradation processes.
  • Intracellular communication pathways, including plastid-to-nucleus signaling and the function of chaperones and proteases, help regulate the chloroplast proteome according to the plant's developmental and stress-related needs.
  • This research demonstrates that modifying the expression of specific nuclear genes related to plastid ribosomal proteins can influence chloroplast degradation and flowering time as a stress response, revealing crucial insights into plant stress management and chloroplast quality control mechanisms.

During a plant's life cycle, plastids undergo several modifications, from undifferentiated pro-plastids to either photosynthetically-active chloroplasts, ezioplasts, chromoplasts or storage organelles, such as amyloplasts, elaioplasts and proteinoplasts. Plastid proteome rearrangements and protein homeostasis, together with intracellular communication pathways, are key factors for correct plastid differentiation and functioning. When plastid development is affected, aberrant organelles are degraded and recycled in a process that involves plastid protein ubiquitination.
