Abstract
Modification of plant growth, especially to develop a more compact plant architecture, is commonly used in commercial ornamental plant production. Such modifications are usually accomplished by means of chemical plant growth regulators that affect the gibberellin synthesis and action. Restrictions over the use of chemical compounds in commercial plant production systems, especially in countries within the European Union, highlight the need for alternative, environmentally friendly methods to achieve such desired goals. Genetic manipulation for compact growth in selected, commercially important, ornamental potted plants such as Kalanchoë blossfeldiana and Petunia hybrida is among the new strategies that are currently being investigated. Overexpression of Arabidopsis thaliana MAP Kinase Substrat-1 (MKS1) resulted in substantial growth reduction in both above-mentioned species. Significant effects were also attained by up-regulation of Nicotiana tabacum GA2ox genes. Introduction of rol-genes by Agrobacterium rhizogenes is considered an alternative strategy for reducing growth in ornamentals. In addition to compactness, some lines also expressed an improved post-production life of the flowers. Most importantly, the resulting lines are not considered as genetically modified organism (GMO) plants, which assists with the introduction of these new lines into commercial production chains. In this review, we will provide an overview of novel methods available for the creation of compact potted ornamental plants.
