Transcription profiling of Arabidopsis to identify genes responsive to non-metabolised glucose analogs: approach to hexokinase-independent glucose sensing

ABSTRACT: It has been strongly argued that plant cells should have a means of sensing sugars at the cell surface, so that extracellular and intracellular sugars can be sensed separately and their metabolism coordinated (Lalonde et al., Plant Cell, 11, 707-26, 2000). There is good evidence for an intracellular hexokinase-dependent pathway of hexose sensing in plants, but very little evidence for a hexokinase-independent signalling pathway, such as that provided by SNF3 or RGT2 in yeast. Many papers on sugar sensing in plants cite work from two laboratories as evidence for hexokinase-independent hexose signalling in plants. The first is that in which cell-wall invertase and sucrose synthase genes were induced by treatment of a Chenopodium suspension culture with 30 mM 6-Deoxyglucose (6DOG) for 24 h (R
