ROSE PLANTS AND METHODS FOR THEIR PRODUCTION AND GENETIC TRANSFORMATION

摘要

Somatic embryos and plantlets are produced from mature rose plant material by culturing in callus induction medium followed by exposure to regeneration medium. Rose plant cells are transformed by incubation with Agrobacterium cells carrying an exogenous DNA sequence. The callus cells may be obtained from various tissue sources, including stamen filaments, leaf explants, and the like, and whole rose plants may be regenerated from the transformed callus cells. The exogenous DNA will be stably incorporated into the chromosomes of the regenerated rose plant which will be able to express gene(s) encoded by the DNA sequence.
