Arabidopsis TIC236 contributes to proplastid development and chloroplast biogenesis during embryogenesis.

ABSTRACT: Plastids are essential, semi-autonomous organelles in plants that carry out a multitude of functions during development. Plastids existing in different subtypes are derived from proplastids progenitors and interconvert in response to environmental and growth cues. Most efforts focus on the differentiation from proplastid to other forms. However, the studies of proplastid development are insufficient and whether proplastid biogenesis affects plant growth is yet to be determined. Arabidopsis TIC236, a translocon component at the inner membrane of the chloroplast envelope, is critical for importing chloroplast-targeted preproteins and chloroplast division. In this study, we uncovered the fundamental influence of proplastid biogenesis on embryo development by exploring the function of TIC236 d
