Department of Botany, University of Wisconsin, Madison, WI 53706, USA
Plant Cell Environ 29:353-66. 2006..Under cold-stress conditions, maltose increases and BAM3 expression is induced. We hypothesize that maltose metabolism is a bridge between transitory starch breakdown and the plants' adaptation to changes in environmental conditions... - The role of cytosolic alpha-glucan phosphorylase in maltose metabolism and the comparison of amylomaltase in Arabidopsis and Escherichia coliYan Lu
Department of Botany, University of Wisconsin, Madison, Wisconsin 53706, USA
