Genetic approaches to understanding sugar-response pathways.

abstract：:Sugars regulate the expression of many genes at the transcriptional level. In Arabidopsis thaliana, sugars induce or repress the expression of >1800 genes, including the STP1 (SUGAR TRANSPORTER PROTEIN 1) gene, which encodes an H(+)/monosaccharide cotransporter. STP1 transcript levels decrease more rapidly after the a...
