A PLANT OF PAPAVER SOMNIFERUM WITH AN ALTERED ALKALOID PROFILE

摘要

There are described plants of Papaver somniferum having reduced expression or activity of magnesium chelatase where-by the plants yield poppy straw having an altered alkaloid profile. In embodiments of the plants the reduced expression or activity of magnesium chelatase is associated with a trait for a lightened leaf colour. There are also described methods for producing the plants, and poppy straw, latex, concentrate of poppy straw and opium from the plants.
