CHLOROPLAST RIBOSOME ASSOCIATED Supports Translation under Stress and Interacts with the Ribosomal 30S Subunit.

abstract：:Several lines of evidence support the proposal that the unusual chloroplast-specific lipid acyl group Delta3,trans-hexadecenoic acid (trans-C(16:1)) stimulates the formation or maintenance of the oligomeric form of the light-harvesting chlorophyll a/b complex (LHCP). To assess the functional significance of this appar...
