Abstract excerpt

Chloroplast biogenesis is a complex process in higher plants. Screening chloroplast biogenesis mutants, and elucidating their molecular mechanisms, will provide insight into the process of chloroplast biogenesis. In this paper, we obtained an early chloroplast biogenesis mutant atecb2 that displayed albino cotyledons and was seedling lethal. Microscopy observations revealed that the chloroplast of atecb2 mutants...
