Abstract excerpt

Karrikin signaling, mediated by the KARRIKIN INSENSITIVE 2 (KAI2) receptor, promotes seed germination, inhibits hypocotyl elongation, regulates root architecture, and mitigates abiotic stresses in plants. DWARF14-LIKE2 (DLK2), encoding a close homolog of KAI2, has been considered a marker gene in karrikin signaling pathway. However, the biological roles of DLK2 in plant growth, development, and abiotic stress...
