The effects of the phytohormone strigolactone (SL) and smoke-derived karrikins (KARs) on plants are generally distinct, despite fact that they perceived through very similar mechanisms. homologous receptors DWARF14 (D14) KARRIKIN-INSENSITIVE2 (KAI2), together with F-box protein MORE AXILLARY GROWTH2 (MAX2), mediate SL KAR responses, respectively, by targeting different SMAX1-LIKE (SMXL) family proteins for degradation. These mechanisms putatively well-insulated, D14-MAX2 SMXL6, SMXL7, SMXL8...
Strigolactones (SLs) are plant hormones with various functions in development, responses to stress, and interactions (micro)organisms the rhizosphere, including seeds of parasitic plants. Their perception for hormonal requires an α,β-hydrolase belonging D14 clade higher plants; host-produced SLs by relies on similar but phylogenetically distinct proteins (D14-like). D14-like peculiar receptors, because they cleave before undergoing a conformational change that elicits downstream events....
In angiosperms, the strigolactone receptor is α/β hydrolase DWARF14 (D14) that, upon binding, undergoes conformational changes, triggers strigolactone-dependent responses, and hydrolyses strigolactones. Strigolactone signalling involves formation of a complex between strigolactone-bound D14, E3-ubiquitin ligase SCFMAX2, transcriptional corepressors SMXL6/7/8, which become ubiquitinated degraded by proteasome. also destabilizes D14 receptor. The current model proposes that degradation occurs...
Abstract Strigolactones (SLs) are carotenoid-derived compounds that regulate various aspects of plant development, physiological responses and interactions with microorganisms. In angiosperms, the SL receptor is α/β hydrolase D14 that, upon binding, undergoes conformational changes, triggers SL-dependent hydrolyses SLs. Arabidopsis signalling involves formation a complex between SL-bound D14, E3-ubiquitin ligase SCF MAX2 transcriptional corepressors SMXL6/7/8 (SMXLs), which become...
