Note:
aphosphoproteins number,
bphosphoprotein spots number correspond to those on 2-DE gels shown in Fig. 4;
cscore;
dtheoretical MW (kDa) and pI.
eMatch peptides;
fchanges of phosphoprotein spots in inferior spikelets as compared to superior spikelets, UR: phosphoprotein upregulated in inferior spikelets as compared to superior spikelets; DR: phosphoprotein downregulated in inferior spikelets as compared to superior spikelets; EGS: early grain-filling stage, MGS: mid-grain-filling stage, LGS: late grain-filling stage.
