CRISPR /Cas9‐mediated editing of 1‐aminocyclopropane‐1‐carboxylate oxidase1 enhances Petunia flower longevity

Summary The genes that encode the ethylene biosynthesis enzyme 1‐aminocyclopropane‐1‐carboxylate oxidase ( ACO ) are thought to be involved in flower senescence. Hence, we investigated whether the transcript levels of Ph ACO genes ( Ph ACO 1 , Ph ACO 3 and Ph ACO 4 ) in Petunia cv. Mirage Rose are associated with ethylene production at different flowering stages. High transcript levels were detected in the late flowering stage and linked to high...
