Identification of more than 200 glucose-responsive Arabidopsis genes none of which responds to 3-O-methylglucose or 6-deoxyglucose

Plant Mol Biol. 2004 Jul;55(4):467-77. doi: 10.1007/s11103-004-1050-0.

Abstract

The response of some plant genes to glucose analogues 3-O-methylglucose (3OMG) or 6-deoxyglucose (6DOG) has been cited as evidence for metabolism-independent glucose signalling. To analyse such signalling using a genetic approach, we sought to identify Arabidopsis glucose-responsive genes which also respond to 3OMG and 6DOG in seedlings. Microarray analysis of gene expression in glucose-treated seedlings and RT-PCR analysis of glucose-treated leaf sections identified more than 200 glucose-responsive genes, but none responded to 3OMG or 6DOG. These data together with other published data on individual genes fail to identify any Arabidopsis sugar-responsive genes which also respond to 3OMG or 6DOG.
