ABSTRACT

The global flower industry thrives on novelty (Chandler et al., 2005). Genetic

engineering is providing a valuable means of improving ornamental crops by the addition of

desirable traits to existing horticulturally-adapted cultivars (Hammond, 2006) or by

expanding the floriculture gene pool to promote the generation of new commercial varieties

(Tanaka et al., 2005). Ornamental plant transformation has advanced considerably in the lastdecade. Now over 40 genera have been reported to be transformed. The primary methods of

creating transgenic ornamental species have been Agrobacterium tumefaciens-mediated

transformation and Microprojectile bombardment (Brand, 2006). Since floricultural and

ornamental crops are grown for aesthetic, non edible purpose there is likely to be less concern

in bio safety issues compared to other food crops (Swarnapiria,2009). Hence, there is

considerable potential for developing transgenics in ornamental crops. The production of

novel flower colour has been the first success story in floriculture genetic engineering. Other

traits that have received attention include floral scent, plant architecture, flower longevity,

disease resistance and abiotic stress resistance (Tanaka et al., 2005).

While technical challenges for production of transgenic ornamental plants still exist,

the greatest challenges to realizing the potential benefits of transgenic ornamental plants arequestionable public acceptance of transgenic plants and the prohibitive costs of generating

environmental impact data needed to gain regulatory clearance (Brand, 2006). Bioluminescent

orchids, novel coloured carnations and blue roses are the significant outcomes of the genetic

transformation studies in ornamentals (Swarnapiria,2009).
