Karrikin 2

Karrikin 2 is a seed germination stimulant that has been found in plant-derived smoke. It induces germination of A. thaliana, L. sativa, E. penduliflora, and S. orbiculatum seeds in a concentration-dependent manner. Karrikin 2 (1 µM) increases expression of the gibberellin (GA) biosynthesis genes GA3ox1 and GA3ox2 and the GA4-responsive gene CP1 in A. thaliana seeds.Formal Name: 2H-furo[2,3-c]pyran-2-one.
