    Research output: Patent


    The present invention provides isolated nucleic acids encoding Chl d synthase, gene constructs comprising the isolated nucleic acids and cells, chloroplasts, plant tissue and whole plants ectopically expressing cyanobacterial Chl d synthase. The invention also provides isolated antibodies prepared using recombinant Chl d synthase. The antibodies and gene constructs of the invention are used to produce Chl d in organisms that do not normally produce Chl d, and to modify Chl d level in cyanobacterial cells, such as for modifying environmental host range and photosynthetic capacity of organisms in low light and/or red or far-red or near far-red light environments.
