Development of genetic improvement procedures for the bioenergy crop, Miscanthus × giganteus (M×g; triploid), are desired for trait improvement. Agrobacterium tumefaciens has been used in other Miscanthus spp. for genetic improvement, but not in M×g, nor have more than a few genes been introduced at a given time. Transformation procedures for M×g were developed; studies included use of A.tumefaciens (strain LBA4404) and A. rhizogenes (strain A4) for introduction of seven genes isolated (by other researchers) from Sorghum bicolor involved in sorgoleone biosynthesis (an allelopathic compound), and selectable marker gene neomycin phosphotransferase II. Procedural development included generation of embryogenic calli from immature inflorescences, attempts to minimize generation of phenolics by these tissues, transformation procedures for both Agrobacterium spp., selection of transgenic tissues, and tissue screenings via polymerase chain reaction to identify putative transgenic tissues/plants. Although four M×g putative transgenic plants were generated, none were proven to be transgenic.
