摘要: Energization of thylakoid membranes brings about the acidification lumenal aqueous phase, which activates important regulatory mechanisms. Earlier Jajoo and coworkers (2014 FEBS Lett. 588:970) have shown that low pH in isolated plant induces changes excitation energy distribution between two photosystems. In order to elucidate structural background these changes, we used small-angle neutron scattering on exposed p2H show gradually lowering from 8.0 5.0 causes small but well discernible reversible diminishment periodic lamellar repeat distance an increased mosaicity - similar effects elicited by light-induced lumen. Our data strongly suggest thylakoids dynamically respond membrane energization actively participate different
