Accumulation of endogenous mRNA for the α subunit of a heterotrimeric G protein in a normal rice cultivar. (A) Northern blot analysis of the mRNA in various tissues at the vegetative growth stage (1.5 mo old). Node A, upper node; Internode, internode between the upper and lower nodes; Node B, lower nodes and internodes. (B) Northern blot analysis of the mRNA from florets at reproductive growth stages (4 mo old). Floret-Be, florets 3 days before fertilization; Floret-Af, florets 3 days after fertilization. (C–E) In situ hybridization of florets, the longitudinal sections of florets on 10 days (C) and 3 days (D) before flowering and 3 days after fertilization (E). The DIG-labeled antisense RNAs were used as a probe. Positive hybridization signals are indicated in blue. Bars = 100 μm. GL, glume; LE, lemma; OV, ovary; PA, palea; PE, pericarp; PI, pistil; ST, stamen.
