Proposed working model for the function of AtNusG in chloroplasts. AtNusG couples the chloroplast PEP complex and chloroplast ribosomes to ensure the rapid synthesis of chloroplast-encoded photosynthetic proteins. In the atnusg mutant, the uncoupling reduced the translation efficiency of these photosynthetic proteins, which could not satisfy the needs of rapid chloroplast development and the establishment of photosynthetic ability in emerging young leaves; cold stress exacerbated the effect on chloroplast development.
