Non-naturally occurring DNA promoters, include MSGT-PFlt, PFlt-UAS-2X and FSgt-PFlt. The MSGT-PFlt was developed and has expression shown to be equivalent to that of CaMV35S promoter. DNA promoters PFlt-UAS-2X and FSgt-PFlt were developed and tested in transient and transgenic system and found to be stronger than the CaMV35S promoter.
