Description | The gene encodes for vacuolar invertase enzyme. The enzymatic assay involving recombinant Vin2 suggest that it lacks fructan biosynthesis enzyme (FBE) activity and possessed a high fructan exohydrolase activity. Compared to Vin1 (GR:0101173) expression of Vin2 was observed in rice plant's peduncle despite the nonaccumulation of fructan in peduncle. Gene expression was also observed in the panicle, flag leaf, and anther. However, it was upregulated under water deficit/drought like conditions. It is expressed maximally starting from heading till 3 days after (50% flowering stage) the heading stage in a panicle. | ||||||
Curator Comment | Due to absence of genes encoding for proteins with fructan biosynthesis enzyme (FBE) activity, rice is suggested to be a fructan nonaccumulator. The rice Vin2 gene is a homolog of Maize gene invertase2 (ivr2, GR:0203986). |
