Abstract

Jasmonic acid (JA) and some of its derivatives are important signals in plant stress responses such as biotic or abiotic stresses during alteration of the environment and are signals in several developmental processes such as trichome development, growth/defense balance, root growth, senescence, or light signaling (Wasternack and Hause 2013). Several specific roles of JA are known for proper organ development of flowers. The most prominent example was found by identification of the JA insensitive mutant of Arabidopsis, CORONATINE INSENSITIVE1 (coi1) which is mutated in the F‐Box protein COI1, a component of the JA receptor complex, the Skp1/Cullin/F‐box (SCF) complex. The mutant coi1 is JA‐insensitive and male sterile (cf. rev. Wasternack and Hause 2013). Surprisingly, the corresponding counterpart jai1 of tomato is also JA‐insensitive and altered in the F‐box protein, but is female sterile (cf. rev. Wasternack and Hause 2013).
