Transcription factors, like MYB4 are capable of activating the expression of multiple genes involved in protection against environmental stresses. The HvWRKY38 or OsMYB4 expression cassettes were introduced into bahiagrass cv. Argentine via biolistic gene transfer and transgenic plants over-expressing these transcription factors have been identified by RT-PCR. Transgenic bahiagrass plants over-expressing HvWRKY38 or OsMYB4 are currently being evaluated under field conditions in Northern Florida to determine productivity and persistence during seasonal environmental stress conditions. In addition we will present physiological data on dehydration and freezing tolerance of bahiagrass plants over-expressing HvWRKY38 or OsMYB4 under controlled environment conditions.
