PLANT BIOTECHOLOGY JOURNAL 21/06/19 CRISPR/Cas9-mediated editing of 1-aminocyclopropane-1-carboxylate oxidase1 enhances Petunia flower longevity. Introduction Petunias, widely used as a bedding plant in the floricultural industry, have become increasingly popular due to their diversity of different flower shapes and colours.

PLANT BIOTECHOLOGY JOURNAL 21/06/19 CRISPR/Cas9-mediated editing of 1-aminocyclopropane-1-carboxylate oxidase1 enhances Petunia flower longevity

Generally, petunias exhibit excellent flower longevity because they continuously produce new flowers over an extended period. However, newly produced individual flowers exhibit rapid senescence in the mother plants. Because petunias are ethylene‐sensitive, their flower senescence is associated with an increase in ethylene production (Woltering and Van Doorn, 1988; Tang et al., 1993; Tang and Woodson, 1996; Huang et al., 2007). Hence, it is necessary to find an effective way to reduce ethylene production. Ethylene is derived from methionine, which is converted to S‐adenosylmethionine (SAM or AdoMet) by SAM synthetase and then to 1‐aminocyclopropane‐1‐carboxylic acid (ACC) by ACC synthetase, before ACC oxidase (ACO) finally converts ACC to ethylene (Yang and Hoffman, 1984).

Résumé traduit : Très peu de variétés ornementales génétiquement modifiées (GM) sont arrivées sur le marché jusqu'à présent. En effet, le processus d'autorisation requis pour de telles usines a un fort impact sur la rentabilité du développement de tels produits. Compte tenu des nombreuses études scientifiques utilisant la modification génétique sur des espèces ornementales d'intérêt, beaucoup de matériel transformé a été produit, pourrait présenter un intérêt commercial et pourrait donc être involontairement mis sur le marché. L'utilisation non intentionnelle de pétunia GM dans les programmes de sélection a en effet été récemment observée. Cette revue répertorie les publications scientifiques utilisant des plantes ornementales GM et tente de déterminer si ces plantes pourraient être détectées par les outils de biologie moléculaire couramment utilisés par les laboratoires de contrôle. – guatemalt

SCIENCEMAG 24/05/17 How the transgenic petunia carnage of 2017 began. Two years ago, plant biologist Teemu Teeri was walking by a train station in Helsinki when he noticed some vivid orange petunias in a planter.

SCIENCEMAG 24/05/17 How the transgenic petunia carnage of 2017 began

The flowers reminded Teeri, who has studied plant pigments at the University of Helsinki, of blooms created in a landmark gene-engineering experiment some 30 years earlier. As far as he knew, those flowers never made it to market. But he was curious, and he stuck a stem in his backpack. Now, that chance encounter has ended up forcing flower sellers on two continents to destroy vast numbers of petunias. Teeri ultimately confirmed that the plants contained foreign DNA, and he tipped off regulators in Europe and the United States, who have identified other commercial strains that are genetically engineered (GE).

EVIRA 27/04/17 Evira removes genetically modified orange petunias from sale. Finnish Food Safety Authority Evira has decided to remove from sale seeds and planting stock of the ornamental plant petunia characterised by the orange colour of the flowers which has been produced by means of genetic engineering.

EVIRA 27/04/17 Evira removes genetically modified orange petunias from sale

Genetically modified varieties of petunia are not authorised for cultivation in the EU. As a result of this, the petunia plants and the seed lot will be destroyed and any plants delivered for further growing on will be recalled from production. GM petunias do not cause any risk to people or the environment In Evira's analyses, one lot of petunia seeds (African Sunset) as well as eight petunia varieties that had already been planted were found to be genetically modified: Pegasus Orange Morn, Pegasus Orange, Pegasus Table Orange, Potunia Plus Papay, Go!

Tunia Orange, Bonnie Orange, Sanguna Patio Salmon and Sanguna Salmon. The cuttings and seeds of the GM petunias have been imported to Finland from Germany and the Netherlands. No risk to people or the environment. MINISTRY OF ENVIRONMENT (LITHUANIA) 02/06/17 Lithuania takes urgent measures to eradicate detected genetically modified petunias from the market.

After request by the European Commission to check whether the genetically modified petunias with orange flowers have spread around the EU member states, they have been discovered in Lithuania as well.

MINISTRY OF ENVIRONMENT (LITHUANIA) 02/06/17 Lithuania takes urgent measures to eradicate detected genetically modified petunias from the market

These plants have already been detected in twelve EU member states: Finland, Germany, the Netherlands, the United Kingdom, etc. “Lithuania,” says Vice-Minister of Environment Mr. Martynas Norbutas, “like all EU member states, where the genetically modified petunias or their seeds have been found, is taking urgent measures to remove them from the market.” This decision was taken during a meeting of specialists of the Ministries of Environment and Agriculture as well as the State Plant Service under the Ministry of Agriculture urgently called yesterday.

It was unanimously agreed that sellers of petunia seeds and seedlings should remove the genetically modified plants from the market and destroy them (seeds should be returned to suppliers). GARDENCENTERMAG 17/05/17 Unauthorized GE petunias: USDA, industry weigh in. On May 14, Garden Center and Greenhouse Management magazines first reported that the United States Department of Agriculture (USDA) is testing potentially genetically engineered (GE) petunias following the news released at the end of April that orange-colored petunia varieties in Europe had been found to be genetically engineered.

Since our initial report, the USDA has responded to several questions regarding a guidance document released May 11 that listed 20 implicated varieties from several breeders that were potentially genetically engineered, and issued instructions for destroying them. The USDA says testing is not complete and that “at least some of the petunias listed are genetically engineered.” They released a bulletin May 16 with an update of the varieties that they have confirmed to be genetically engineered, which includes different varieties than the list from the May 11 document: Chris Berg of Westhoff echoed this sentiment that the industry was taken aback by this news.

SEPPI OVER BLOG 14/11/17 Pétunias « OGM » : le ridicule exposé et expliqué. Il y a quelques mois, un biologiste des plantes finlandais de l'Université d'Helsinki se promenait dans la ville, lorsqu'il a remarqué des pétunias oranges dans des jardinières sur une place publique.

Il était intrigué, car il n'y a pas de variété naturelle de pétunia de cette couleur. Une histoire vieille de 20 ans d'une expérience de recombinaison de gènes lui est alors venue à l'esprit. Il a acheté les mêmes plantes dans un magasin, les a analysées et a découvert qu'elles étaient des « descendantes » des produits d'une vieille expérience : d'une manière ou d'une autre, ces semences étaient devenues disponibles sur le marché, probablement depuis des années. Une fois l'histoire rendue publique, une ruée vers la localisation et la destruction des graines et des fleurs « OGM » a été déclenchée par les agences de régulation, de la Finlande au Royaume-Uni, de l'Australie aux États-Unis et d'autres pays.
