“…50 analogs (Nelson et al 2012). In one of the studies (Krawczyk et al 2017), tricyclic butenolides (KAR 1 with an additional aromatic ring or an aromatic ring without the methyl group at the C3 position of karrikin) were applied to dormant and non-dormant A. fatua caryopses. A low stimulatory effect on germination of dormant caryopses was shown only by those butenolides without the methyl group.…”

Plant-derived smoke, its water extract-the smoke water (SW), and karrikin (KAR 1) present in the smoke stimulate seed germination in plants from fire-prone and fire-free areas, including weeds and cultivated plants. There are also plants, the seeds of which can respond only to smoke, but not to KAR 1 , and vice versa. Smoke and/or KAR 1 can be applied in horticulture, agriculture, and revegetation. This review describes effects of smoke and KAR 1 on weed seed germination and focuses mainly on the recent knowledge about the physiological role of these factors in dormancy release and germination of Avena fatua caryopses. The involvement of gibberellins, ethylene, and abscisic acid (ABA) in the response to smoke or KAR 1 is discussed. Effects of smoke or KAR 1 on the contents of reactive oxygen species (ROS), non-enzymatic antioxidants, and activity of the enzymes participating in ROS removal are presented. Cell cycle activity in the response to SW and KAR 1 is also considered. Effects of KAR 1 on thermodormancy release in A. fatua caryopses are highlighted, as well.

“…Smoke generating from burning plant material has been known to contain karrikins (KAR 1 )—chemicals that are powerful germination promoters. KAR 1 plays a major role in natural systems as it is highly active at very low concentrations, shows great potential in agriculture [1] and is promising to be a new plant growth regulator [2,3,4,5,6,7,8]. Until now the effects and potential mechanisms of KAR 1 on the accumulation of secondary metabolite in medicinal plants has not been reported.…”

Smoke-Isolated Karrikins Stimulated Tanshinones Biosynthesis in Salvia miltiorrhiza through Endogenous Nitric Oxide and Jasmonic Acid

Although smoke-isolated karrikins (KAR1) could regulate secondary metabolism in medicinal plants, the signal transduction mechanism has not been reported. This study highlights the influence of KAR1 on tanshinone I (T-I) production in Salvia miltiorrhiza and the involved signal molecules. Results showed KAR1-induced generation of nitric oxide (NO), jasmonic acid (JA) and T-I in S. miltiorrhiza hairy root. KAR1-induced increase of T-I was suppressed by NO-specific scavenger (cPTIO) and NOS inhibitors (PBITU); JA synthesis inhibitor (SHAM) and JA synthesis inhibitor (PrGall), which indicated that NO and JA play essential roles in KAR1-induced T-I. NO inhibitors inhibited KAR1-induced generation of NO and JA, suggesting NO was located upstream of JA signal pathway. NO-induced T-I production was inhibited by SHAM and PrGall, implying JA participated in transmitting signal NO to T-I accumulation. In other words, NO mediated the KAR1-induced T-I production through a JA-dependent signaling pathway. The results helped us understand the signal transduction mechanism involved in KAR1-induced T-I production and provided helpful information for the production of S. miltiorrhiza hairy root.
