Ligand-receptor co-evolution shaped the jasmonate pathway in land plants
The phytohormone jasmonoyl-isoleucine (JA-Ile) regulates defense, growth and developmental responses in vascular plants. Bryophytes have conserved sequences for all JA-Ile signaling pathway components but lack...

An OPR3-independent pathway uses 4,5-didehydrojasmonate for jasmonate synthesis
OPR3 is required to reduce the JA-Ile precursor OPDA. Analyses of JA levels in a loss-of-function opr3-3 mutant identified an OPR3-independent pathway for JA-Ile biosynthesis, based on OPDA conversion to 4,5-ddh-...
