Abstract:
The pedicel region of Zea mays kernels contains a unique form of maize glutamine synthetase (GS), GSp1. RNA blot analysis using GS gene-specific probes revealed that the expression of the GS1-2 gene was specific to the pedicel and that it increased in the kernels during development. This pattern of the maize GS1-2 gene expression is consistent with the tissue specificity of the GSp1 protein and suggests that it encodes the GSp1 isoform of maize GS.
