Abstract excerpt
To elucidate mechanisms that regulate chloroplast RNA splicing in multicellular plants, we sought nuclear mutations in maize that result in chloroplast splicing defects. Evidence is presented for two nuclear genes whose function is required for the splicing of group II introns in maize chloroplasts. A mutation in the crs1 (for chloroplast RNA splicing 1) gene blocks the splicing of only the atpF intron, whereas a...
