ornamental-horticulture
Ornamental horticulture is the science and practice of cultivating plants primarily for their aesthetic value, encompassing breeding, propagation, and cultivation of flowering plants, foliage species, and landscape plants. It intersects deeply with plant science through research into traits like flower color, leaf morphology, stress tolerance, and disease resistance that govern both visual appeal and plant health. Advances in this field drive broader understanding of plant genetics, developmental biology, and physiology with applications across agriculture and conservation.

Scientists developed the first reliable method to grow and genetically modify Hosta 'Light Star' in the lab, using a color-changing reporter gene that turns transformed plants red — making it easy to spot successful genetic edits without destructive testing.
Optimal callus induction medium achieved a 53.33% induction rate from leaf explants using MS medium with 6-BA, NAA, and 2,4-D.
Adventitious bud proliferation reached a coefficient of 5.87, and both rooting and transplant survival hit 100% under optimized conditions.
The RUBY reporter gene enabled non-invasive visual screening of successfully transformed plants by turning them red, simplifying the identification of positive transformants.
