Alkaline/neutral invertase CINV1

Gene

CINV1

Organism
Arabidopsis thaliana (Mouse-ear cress)
Status
Reviewed-Annotation score: Annotation score: 5 out of 5-Experimental evidence at protein leveli

Functioni

Cytosolic invertase that specifically cleaves sucrose into glucose and fructose and is involved in the regulation of multiple tissue development including primary root elongation, root hair growth, leaf and silique development, and floral transition. Is involved in osmotic stress-induced inhibition on lateral root growth by controlling the concentration of hexose in cells. May regulate sugar-mediated root development by controlling sucrose catabolism in root cells.4 Publications
