Transcription profiling of wild type, mur4 knock-out and prl1 knock-out Arabidopsis plants grown in media with 1% glucose

ABSTRACT: Sugars such as glucose function as signal molecules that regulate gene expression, growth and development in plants, animals and yeast. To understand the molecular mechanisms of sugar responses, we isolated and characterized an Arabidopsis thaliana mutant, high sugar- response 8 (hsr8), which enhances sugar responsive growth and gene expression. Light- grown hsr8 plants exhibited increased starch and anthocyanin and reduced chlorophyll content in response to glucose treatment. Dark- grown hsr8 seedlings show glucose- hypersensitive hypocotyl elongation and development. The HSR8 gene, isolated using map-based cloning, is allelic to the MUR4 gene involved in arabinose synthesis. Dark- grown mur1 and mur3 seedlings also exhibit similar sugar responses to hsr8/mur4. The sugar- hypersensitive p
