Local manufacturing: A center for photosystem biogenesis

Abstract

Photosystem biogenesis in the chloroplast requires a concerted effort between synthesis and assembly of components including protein subunits, pigments, and other cofactors that varies both temporally and spatially. Sun et al. (2019) investigate the translation zone (T-zone) of unicellular alga Chlamydomonas reinhardtii (Chlamydomonas) chloroplasts as the primary location for biogenesis of PSI and PSII before redistribution throughout the organelle.
