The native S. nigrum gene LOX3 (S. nigrum lipoxygenase 3) codes for
a jasmonic acid biosynthesis enzyme.
Jasmonates are known plant signalling substances. They play an
important role in development processes (maturation of pollen,
fruit and seed) and also in plant reactions to biotic and abiotic
stress factors, including the production of antibodies for the
direct and indirect defence of plants against chewing insects.
Constitutive reduction of the lipoxygenase 3 contents can influence
one of the insect-induced plant defence cascades, it can alter the
defence response of the plant to abiotic and other biotic stress
factors, and it can affect the development processes of the plant
