Expression of 35S:ΔCSA1 in the Wild-Type Background Phenocopies the csa1 Plant.
(A) Hypocotyl length of wild-type and two independent transgenic plants expressing the 35S:Δcsa1 construct, grown for 4 d under red or blue light.
(B) Hypocotyl length of plants grown for 4 d under white light with a high red:far-red ratio (8 h light/16 h darkness).
(C) Expression levels of CSA1 in wild-type plants and two independent transgenic plants expressing the 35S:Δcsa1 construct determined by RT-PCR using primers that amplify the first exon.
