An evolutionarily ancient plant hormone receptor complex comprising the α/β-fold hydrolase KARRIKIN INSENSITIVE 2 (KAI2) and F-box protein MORE AXILLARY GROWTH (MAX2) mediates a range of developmental responses to smoke-derived butenolides called karrikins (KARs) yet elusive endogenous KAI2 ligands (KLs). Degradation SUPPRESSOR OF MAX2 1 (SMAX1) after ligand perception is considered be key step in KAR/KL signaling. However, molecular events which regulate development downstream SMAX1 removal...
The α/β hydrolase KARRIKIN INSENSITIVE 2 (KAI2) functions as a receptor for yet undiscovered phytohormone, provisionally termed KAI2 ligand (KL). In addition, it perceives karrikin, butenolide compound found in the smoke of burnt plant material. KAI2-mediated signaling is involved regulating seed germination and shaping seedling adult morphology, both above below ground. It also governs responses to various abiotic stimuli stresses shapes biotic interactions. being linked an elaborate...
SUMMARY KARRIKIN INSENSITIVE2 (KAI2) is an α/β‐hydrolase required for plant responses to karrikins, which are abiotic butenolides that can influence seed germination and seedling growth. Although represented by four angiosperm species, loss‐of‐function kai2 mutants phenotypically inconsistent incompletely characterised, resulting in uncertainties about the core functions of KAI2 development. Here we characterised developmental grass Brachypodium distachyon using molecular, physiological...
Abstract Karrikins (KARs) are bioactive molecules derived from burning vegetation. Plants perceive KARs through the α/β hydrolase KARRIKIN INSENSITIVE 2 (KAI2) that interacts with F-box protein ubiquitin ligase MORE AXILLARY GROWTH (MAX2). MAX2 also plays a role in perception and signal activation by Strigolactone (SL), phytohormone controlling various developmental processes plants. SL acts as rhizosphere to activate arbuscular mycorrhiza fungi can be exploited parasitic kai2 knockouts...
