  • FUNCTION Cell wall-associated invertase that cleaves sucrose into glucose and fructose and is required for assimilated carbon partitioning during early grain-filling. May be involved in sucrose unloaded in the ovular and stylar vascular tissues for the stimulation of starch synthesis in the developing endosperm during grain-filling (PubMed:18820698). Sugar homeostasis mediated by CIN2/GIF1 plays an important role in constitutive and induced physical and chemical defense against pathogens (PubMed:24118770).CATALYTIC ACTIVITY Hydrolysis of terminal non-reducing beta-D-fructofuranoside residues in beta-D-fructofuranosides.SUBCELLULAR LOCATION Associated with the cell wall.TISSUE SPECIFICITY Expressed in leaves and flowers. Weakly expressed in seeds (PubMed:15759120). Expressed in growing roots, node and the rapidly elongating zone of the internode (PubMed:18820698).DEVELOPMENTAL STAGE Expressed throughout flowering, with higher expression from 1 to 6 days after flowering (PubMed:15759120). During early grain-filling, expressed in the ovular vascular and lateral stylar vascular traces (PubMed:18820698).INDUCTION By sucrose in caryopsis from 1 to 2 and from 9 to 10 days after flowering.DISRUPTION PHENOTYPE Slow grain-filling resulting in reduced weight of grains containing loosely packed starch granules and reduced levels of amylose and amylopectin.BIOTECHNOLOGY CIN2/GIF1 is a potential domestication-selected gene that controls grain filling and yield, and could be used for further crop improvement.SIMILARITY Belongs to the glycosyl hydrolase 32 family.
