A model of ABA response in an ONSEN-integrated mutant.
ONSEN is inserted into an intron of an ABA-responsive gene. (a) An ABA-insensitive mutant is crossed with nrpd1. The ABA-insensitive phenotype appears in an F2 segregant that is homozygous on the ONSEN insertion locus. (b) An ABA-insensitive mutant is crossed with a wild-type plant. IBM2 is recruited on the ONSEN insertion locus by RdDM and ONSEN insertion is masked in the F1 and F2 segregants, resulting in ABA-sensitive phenotypes.
