Northern hybridization analysis of TRAB1. Thirty micrograms of RNA was subjected to Northern hybridization analysis by using a TRAB1 cDNA probe. RNA was from leaves (lanes 1 and 2) and roots (lanes 3 and 4) of young rice plants (14 days old) treated with 10−4 M ABA for 6 h (lanes 2 and 4) or receiving no ABA (lanes 1 and 3), suspension-cultured cells (Oc cells) treated with 5 × 10−5 M ABA for 6 h (lane 6) or receiving no ABA (lane 5), and rice embryos at 13–14 days after flowering (lane 7) or at dry mature stage (lane 8). The entire TRAB1 cDNA was used for the probe.
