Northern blot analysis of RNA from different parts of the rice plant. N2, second highest node; N1, highest node containing the apical meristem; L2b, basal 2 cm of the second leaf blade; L2s, basal 2 cm of second leaf sheath; L1, youngest leaf; Co, coleoptile, 3 days after germination; Ro, root, 3 days after germination; 0–3, internodal region 0–3 mm above N2, containing the intercalary meristem; 3–8, internodal region 3–8 mm above N2, containing mostly the elongation zone; 8–18, internodal region 8–18 mm above N2, containing the upper part of the elongation zone and the differentiation zone; old, oldest part of the internode. (Upper) The hybridization signals with Os-RPA1 as probe. (Lower) The hybridization signals with E37 used as internal loading control.
