LUH Regulates a Subset of PIF1-Regulated Genes in Imbibed Seeds.
(A) The expression levels of GA and ABA biosynthetic genes in wild-type, luh-3 mutant, and pif1 mutant seeds treated with a far-red light pulse for 5 min and incubated for 12 h in darkness (phyBoff condition) (sd, n = 3 biological replicates).
(B) The expression levels of PIF1-regulated targets under the phyBoff condition (sd, n = 3 biological replicates).
