The pedicel region of Zea mays kernels contains a unique form of maize glutamine synthetase (GS), GSpl. RNA blot analysis using GS gene-specific probes revealed that the expression of the GS,.2 gene was specific to the pedicel and that it increased in the kernels during development. This pattern of the maize GS,.2 gene expression is consistent with the tissue specificity of the GSpl protein and suggests that it encodes the GSpl isoform of maize GS.
