Abstract
Conventional breeding of ornamental plants is a long and costly process.
Transgenesis has been used to accelerate the improvement of ornamental plants and to bring genetic diversity.
Research on transgenic ornamentals including roses, chrysanthemums, petunias, and carnations has been conducted to improve biotic and abiotic stress resistance, modification of flower color, plant growth and development, flowering time, and fragrance compounds.
Since 2012 a total of 150 ornamental species genomes have been sequenced.
The emergence of gene-editing tools such as the CRISPR-Cas system (Clustered Regularly Interspaced Short Palindromic Repeats (CRISPR)-associated protein) along with genome sequencing can accelerate breeding programs and meet the demands of the ornamental horticulture industry.
Several species have been edited, such as chrysanthemum, euphorbia, ipomoea, lily, petunia, torenia, and the orchid family, modified mainly for delaying petal senescence, the color of flowers and leaves, and to obtain double flowers.
We present the current state of sequenced plant genomes, the potential of new genomic techniques, and their regulations in the countries.
