Substrate Report for: Karrikin-1

Karrikins (KAR) are butenolide molecules produced during wildfires in smoke and deposited on soil surface. They are absorbed by seeds and activate germination. Strigolactones (SL) are different butenolide plant hormones with tricyclic lactone, that influence root branching leaf shape and senescence. KAI2 and D14 are paralogous alpha/beta hydrolase receptors respectively for KARS and SLs they belong to the RsbQ-like family. KAI2 (KARRIKIN-INSENSITVE-2) and D14 (DWARF14) are both receptors and enzymes.KAR1 showed potent germination activity (<1 nM) with the key bioassayspecies: Grand Rapids lettuce seed (Lactuca sativa cv) and smoke-responsive Australian (Conostylis aculeata, Stylidium affine), South African (Syncarpha vestita) and North American species (Nicotiana attenuata, Emmenanthe penduliflora)
