Abstract Background Next-generation transgenic plants will require a more precise regulation of transgene expression preferably under the control of native promoters. A genome-wide T-DNA tagging strategy was therefore performed for the identification and characterization of novel banana promoters. Embryogenic cell suspensions of a plantain-type banana were transformed with a promoterless codon-optimized luciferase luc gene and low temperature-responsive luciferase activation was monitored in real time. Results Around l6 000 transgenic cell .
