The cruciferous (Brassicales) are an order of the flowering plants (Magnoliopsida).

features

Most representatives of the order are distinguished by the presence of mustard oil glycosides and, associated with them, the enzyme myrosinase . If the tissue is damaged, the myrosinase emerges from special idioblasts and releases mustard oil from the glycosides , which is used to ward off herbivores . Outside of the order, mustard oil glycosides are only known from the genus Drypetes (family Putranjivaceae , order Malpighiae ).

The ovary usually consists of three intergrown carpels and is on top. The placentation is parietal and the embryos are often green.

Systematics

The Brassicales order is the sister group of the Malvales within the Eurosiden II . It includes the following families:
