Glz2: Important Genes In Arabidopsis Glucose Signaling Pathway

Recent studies have demonstrated that glucose plays an essential role in plant signaling pathways as well as in providing energy and structural components. In this work, we report a new Arabidopsis T-DNA insertion mutant glz2, which exhibits several developmental defects such as reduced apical dorminance, increased auxillary meristem, smaller and darker green rosette, short primary root, and late flowering. Physiological experiments revealed that glz2 mutant was defective in glucose response. Our results indicate that the GLZ2 gene may regulate Arabidopsis growth and development through HXK-dependent signaling pathway.
