GRF5 Represses CBF Gene Expression in a GA-Modulated Manner.

(A) Schematic representation of the interactions in response to cold stress as determined in this study with a special emphasis on a possible crosstalk of the GA- and DELLA-dependent GRF5 regulation in the cold and cold stress-induced gene expression.

(B) and (C) Graphs displaying reads per kilobase of transcript per million mapped reads (RPKM) values of CBF1 to CBF3 (B) and CBF target (C) gene expression of seedlings grown in ambient temperature (21°C) or in cold stress (4°C) in the absence (mock) and presence of 100 µM GA₃. Shown are means and sd of three biological replicate samples from pooled seedling shoots.
