Abstract
Navadna konoplja (Cannabis sativa L.) je razširjena rastlina z zapleteno fitokemijo in bogatim sekundarnim metabolizmom. Sekundarni metaboliti so snovi, katerih vloga je interakcija rastline z okoljem. Njihova sinteza je pogojena s prisotnostjo stresa in je energetsko zelo potratna. Rastline varujejo pred škodljivci in patogeni ter abiotskimi dejavniki. V konoplji so v največji meri prisotni kanabinodi, terpenodi in flavonoidi, skoncentrirani v socvetjih ženskih rastlin. Njihova ekološka vloga in delovanje ni povsem raziskano. Kanabinoidi Δ-9-trans-tetrahidrokanabinol (Δ9-THC), kanabidiolna kislina (CBDA) in drugi naj bi bili vpleteni v antioksidativne procese in obrambni sistem rastline, zaradi prostorsko izolirane sinteze in citotoksičnih stranskih produktov. Ob prisotnosti stresa pride do povečanja njihove vsebnosti in spremembe kemijskega profila. Stres aktivira stresne signalne molekule – jasmonsko kislino in njene derivate, ki vplivajo na sproščanje terpenodiov, ter poveča izražanje genov v fenilpropanoidni poti, ki je ključna za sintezo flavonoidov. Sekundarni metaboliti delujejo sinergično in v povezavi z mikrobiomom – endofitnimi bakterijami in glivami – negativno vplivajo na škodljive organizme ter varujejo rastlino.
