  • Title: The maize glutamine synthetase GS1-2 gene is preferentially expressed in kernel pedicels and is developmentally-regulated.
    Author: Rastogi R, Chourey PS, Muhitch MJ.
    Journal: Plant Cell Physiol; 1998 Apr; 39(4):443-6. PubMed ID: 9615467.
    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.
