qRT-PCR analysis of the expression pattern of REL2. Total RNA was extracted from various tissues from callus and WT plants. Rice Actin1 gene was used as a control. The expression of REL2 in roots at heading stage was set to 1. The 1^st leaf blades or 2^nd leaf blade mean the position of leaf blades or leaf sheaths. From up to down of a rice plant, the first leaf blade or leaf sheath is the 1^st leaf blade or leaf sheath and the second leaf blade or leaf sheath is the 2^nd leaf blade or leaf sheath. The values are the mean ± SEM with three biological replicates
