expression in Escherichia coli | Chromochloris zofingiensis |
expression in Escherichia coli | Chlamydomonas reinhardtii |
transgenic Arabidopsis thaliana expressing the beta-carotene ketolase from Chlamydomonas reinhardtii develop orange leaves which accumulate astaxanthin up to 2 mg/g dry weight with a 1.8fold increase in total carotenoids. The ketolases with high activity of converting zeaxanthin to astaxanthin triggers transgenic Arabidopsis to accumulate large amounts of astaxanthin in leaves and seeds | Chromochloris zofingiensis |
