Abstract

Derived from burnt vegetation, karrikins (KAR) are butenolide chemicals that stimulate seed germination and enhance seedling responses to light. Genetic and biochemical studies have identified KARRIKIN INSENSITIVE2 (KAI2) as a putative karrikin receptor protein (reviewed by Waters et al., 2014). KAI2 is an α/β-fold hydrolase and a paralog of DWARF14 (D14; AtD14 in Arabidopsis), and both possess the conserved catalytic triad of Ser, His, and Asp residues typical of this class of hydrolytic enzymes.
