Expression

GA2ox6, its mRNAs accumulated in leaves after the phase transition from vegetative to reproductive growth. GA2ox6 mRNA could also be detected in leaves at early seedling stage and transiently at high level during the active tillering stage.Since expression of most GA2oxs terminated after the active tillering stage, the pattern of tiller growth throughout the rice life cycle was examined. Tiller number increased from 30 to 50 DAI (active tillering), remained constant until 75 DAI, and then increased again until 90 DAI (late tillering)when the experiment was terminated (Figure 3C). Expression of each group of GA2oxs paralleled the active and late tillering stages (cf. Figures 3B with 3C).Germination was observed from 1 DAI and reached almost 100% at 2 DAI (Figure 4A). Total RNA was isolated from embryos after imbibition of seeds, and temporal expression profiles of six GA2oxs were analyzed by RT-PCR. The accumulation of most GA2ox mRNAs was detectable starting from 0 to 1 DAI and maintained at similar levels afterward, GA2ox6 had a distinct expression pattern, as its mRNA quickly accumulated from 0.5 to 1 DAI and then decreased significantly from 2 to 4 DAI.
