1 The Arabidopsis sweetie mutant is affected in carbohydrate metabolism and defective in the control of growth, development and senescence. Carbohydrates HEAT repeat-containing protein Arabidopsis thaliana
2 Here we report the characterization of a novel Arabidopsis thaliana mutant, sweetie, with drastically altered morphogenesis, and a strongly modified carbohydrate metabolism leading to elevated levels of trehalose, trehalose-6-phosphate and starch. Trehalose HEAT repeat-containing protein Arabidopsis thaliana
3 Here we report the characterization of a novel Arabidopsis thaliana mutant, sweetie, with drastically altered morphogenesis, and a strongly modified carbohydrate metabolism leading to elevated levels of trehalose, trehalose-6-phosphate and starch. trehalose-6-phosphate HEAT repeat-containing protein Arabidopsis thaliana

11 However, SWEETIE encodes a protein that is unrelated to any known enzyme involved in sugar metabolism. Sugars HEAT repeat-containing protein Arabidopsis thaliana
12 We suggest that SWEETIE plays an important regulatory function that influences multiple metabolic, hormonal and stress-related pathways, leading to altered gene expression and pronounced changes in the accumulation of sugar, starch and ethylene. Sugars HEAT repeat-containing protein Arabidopsis thaliana
