Table 2 Phosphate content of tuber starches from lines exhibiting silencing of GBSS (1041 lines) or overexpressing SBEII (1047 lines)

From: Overexpression of STARCH BRANCHING ENZYME II increases short-chain branching of amylopectin and alters the physicochemical properties of starch from potato tuber

  1. WT: wild-type; EV: empty vector. Data are mean nmol Glc6P per mg starch ± SD and mean nmol Glc3P per mg starch ± SD (n = 3 biological replicates). Total nmol phosphate per mg starch was calculated as the sum of C6 plus C3 phosphates.
