Determination of exogenous IAA and DEG functions. A Phenotypic growth assay of transgenic INVSc1 cells under cold stress. Aliquots of serially diluted (1, 10− 1, 10− 2, 10− 3, 10− 4, and 10− 5) cultures on SC-Ura medium after cold treatment with the pYES2 empty vector and pYES2-IAA30. B and C Dynamic physiological changes after addition of exogenous IAA. Different capital letters indicate significant differences within the same treatment of the same variety. Different lowercase letters indicate significant differences among the different treatments of the same variety. p < 0.05
