Abstract
Karrikins are a family of compounds produced by
wildfires that can stimulate the germination of dormant
seeds of plants from numerous families. Seed plants
could have ‘discovered’ karrikins during fire-prone times
in the Cretaceous period when flowering plants were
evolving rapidly. Recent research suggests that karrikins
mimic an unidentified endogenous compound that has
roles in seed germination and early plant development.
The endogenous signalling compound is presumably
not only similar to karrikins, but also to the related
strigolactone hormones.
