LEFKOTHEA Regulates Nuclear and Chloroplast mRNA Splicing in Plants (Developmental Cell)

Daras et al. show that in higher land plants, both nuclear and chloroplast pre-mRNA splicing involve a common nuclear-encoded protein, LEFKOTHEA. Starting in the early stages of embryo development, LEFKOTHEA coordinates the expression of the nuclear and chloroplast genomes, thus regulating plant growth.
