Western blotting for comparing 14-3-3 protein and ADPase expressions of superior spikelets (SS) and inferior spikelets (IS) at three grain-filling stages.

<p>Gels were divided into two parts at a molecular mass of approximately 66-3-3 protein and ADPase. EGS, MGS and LGS represent early, mid-, and late grain-filling stage, respectively, of endosperm development stages of SS and IS.
