High RH reduced leaf [ABA] more in the sensitive genotype than in the tolerant one Several genes acted together towards genotypic tolerance to high RH.
NCED1, UGT75B2, BG2, OST1, ABF3 and RhAPX seem to be involved in tolerance to high RH.
CYP707A3 and BG1 had a minor contribution to tolerance to high RH.
AAO3, CYP707A1 and DREB1B did not contribute to this genotypic tolerance trait.
