Satellite Symposium 5: Molecular Breeding

Description

Hygromycin selection for the hpt gene, expressed from the CaMV-35S promoter, has been successful in transgenesis of a limited number of grass species. As an alternative to hpt selection Altpeter et al., (2000) reported successful transformation using paromomycin selection for the nptII gene expressed by the maize ubiquitin promoter. We have tested the utility of a number of selection cassettes using previously sporadically transformable species which nevertheless had very good tissue culture and regeneration protocols.
