Microspore culture can be used for homozygous dihaploid plant production and the uninuclear origin of microspore-derived dihaploid plant is an excellent basis for plant transformation, as a plant with integrated foreign gene in a homozygous set can be obtained in a considerably short time. An electroporation method for delivery of foreign DNA into mechanically isolated microspores of maize (Zea mays L.) was developed. Different media for electroporation and different concentrations of plasmid DNA were tested. Physical factors affecting efficiency of electroporation (number of pulses, duration of the pulse, voltage, frequency) and plasmid DNA concentration were optimised and discussed, relating to microspore viability, induction of gametic embryogenesis after electroporation, and the number of GUS expressing microspores.
