A sister protein of the KAR/KL receptor can negatively regulate karrikin signaling in Arabidopsis
Plant Science Research WeeklyKarrikins (KARs) are a class of molecules that are hypothesized to mimic an undiscovered plant hormone KL (KAI2 Ligand). The signaling cascade triggered by KAR/KL is initiated by the α/β-hydrolase, KAI2, and can regulate several traits like germination, stress tolerance, and others. KAI2 is related…
