Table I. Starch content at the end of the day in leaves of mutants with starchless or low-starch phenotypes.
Values are means ± se of measurements on six samples, each consisting of fully expanded leaves from the upper part of the shoot of a single plant. n.d., Not detected.

For each genotype, F3 homozygous mutant and wild-type plants for analysis were selected by genotyping individual plants in a single F2 population derived from a cross between the original mutant in Gifu and MG-20. Plants were grown for 7 weeks, as described for starch quantification in “Materials and Methods.”
