The Change in Chain Length Distribution of Amylopectin in Rice Endosperm between Various pho1 Mutants and Their Wild-Type Parents (T65 or Kinmaze) as Determined by the APTS-Capillary Electrophoresis Method.
The change in the molar amounts (y axis) of specific size chains (x axis) between various pho1 mutants and their wild-type parent, T65 or Kinmaze, are depicted. For pho1 mutants BMF136 and 134, differences in chain length distribution for pseudonormal (pn), shrunken (sh), and white-core grain (wcg for BMF 134 only) from wild-type T65 are shown. BMF136 and BMF134 are near isogenic lines derived from crosses between the parent cultivar, T65, and EM755 and EM719, respectively. BMF10 is a near isogenic line from a cross between cv Kinmaze and EM141. AMF46 is an amylose-free pho1 double mutant line (pho1/pho1 wx/wx) derived from a cross between a waxy mutant (wx, EM583) and pho1 mutant EM755.
