16-4 Pathway engineering in plant plastids improves plant productivity: CAS IGDB

A team around Caixia GAO at CAS Institute of Genetics and Developmental Biology found that the specific activity of phoshpoglucose isomerase PGI localized in cytosol (PGIc) was much higher than its plastidic isoenzyme counterpart (PGIp). Engineering of PGIc into chloroplasts of a pgip mutant of Arabidopsis thaliana (atpgip) resulted in starch over-accumulation, higher photosynthesis rate, up to 19% more plant biomass and 27% seed yield productivity.
