A genetically modified tree (GMt, GM tree, genetically engineered tree, GE tree or transgenic tree) is a tree whose DNA has been modified using genetic engineering techniques. In most cases the aim is to introduce a novel trait to the plant which does not occur naturally within the species. Examples include resistance to certain pests, diseases, environmental conditions, and herbicide tolerance, or the alteration of lignin levels in order to reduce pulping costs.

  • Un arbre génétiquement modifié (arbre OGM ou arbre transgénique) est un arbre dont le génome a été modifié à l'aide de techniques de génie génétique, généralement par insertion de fragments d’ADN d’autres espèces. L’objectif est d’introduire dans la plante un caractère (transmissible à sa descendance ou, potentiellement, non transmissible via un gène « terminator ») et n’existant pas naturellement dans la nature ou au sein de l’espèce (ex : résistance à des insectes, bactéries, champignons, virus ou parasites, à des stress environnementaux tels que la sécheresse, la chaleur, le gel et/ou la salinisation, une croissance accélérée, une tolérance à un herbicide total, ou encore un bas taux de lignine pour de réduire les coûts de production de la pâte à papier)°.

  • Генетически модифицированное дерево — дерево, генотип которого был искусственно изменён при помощи методов генной инженерии. Первые результаты исследований были получены в 1988 г. Посадка ГМ-деревьев лесных пород в промышленном масштабе впервые началась в Китае в 2002 г.. (ru)
  • الأشجار المعدلة وراثيا هي شجرة عُدل في حمضها الوراثي باستخدام تقنيات الهندسة الوراثية.تهدف في معظم الحالات إلى إدخال خلة جديدة إلى النبتة لاتوجد بشكل طبيعي في نوعها، مثال إدخال المقاومة لمرض أو وباء معين في النبات، أو لأجل أن تتكيف مع حالة البيئة أو مع المبيدات الحشرية ، تبديل مستويات ليغنين من أجل تقليل كلفة استخراج الورق.
