520 |a From a T-DNA-tagging population in rice, we identified OsGASR1 (LOC_Os03g55290), a member of the GAST (gibberellin (GA)-Stimulated Transcript) family that is induced by salt stress and ABA treatment. This gene was highly expressed in the regions of cell proliferation and panicle development, as revealed by a GUS assay of the mutant line. In the osgasr1 mutants, the second leaf blades were much longer than those of the segregating wild type due to an increase in cell length. In addition, five α-amylase genes were up-regulated in the mutants, implying that OsGASR1 is a negative regulator of those genes. These results suggest that OsGASR1 plays important roles in seedling growth and α-amylase gene expression
