Abstract
The spatial organization of the de novo assembly of photosystem II (PSII) in cyanobacteria, particularly its subcellular starting point, is a matter of ongoing scientific debate. Here, we use fluorescence microscopy and biochemical experiments to demonstrate that the most likely marker of early PSII biogenesis, i.e., the precursor of the D1 protein of the PSII reaction centre, accumulates primarily at thylakoid convergence zones close to the periphery of the cell.
期刊介绍:
Physiologia Plantarum is an international journal committed to publishing the best full-length original research papers that advance our understanding of primary mechanisms of plant development, growth and productivity as well as plant interactions with the biotic and abiotic environment. All organisational levels of experimental plant biology – from molecular and cell biology, biochemistry and biophysics to ecophysiology and global change biology – fall within the scope of the journal. The content is distributed between 5 main subject areas supervised by Subject Editors specialised in the respective domain: (1) biochemistry and metabolism, (2) ecophysiology, stress and adaptation, (3) uptake, transport and assimilation, (4) development, growth and differentiation, (5) photobiology and photosynthesis.
