Extended Data Fig. 6: Functional analysis of su1 alleles.

Significant differences between Su1-RC and Su1-B73 alleles across the sweet corn population in sucrose (a), maltose (b), glucose (c), and fructose (d), respectively. e, Significant differences in expression levels among four su1 alleles. f, Significant differences in flavor values among four alleles of su1. g, Correlation analysis between pericarp thickness from taste rating experiments and su1 expression levels. h, Sweetness from taste rating experiments, showing no difference between Su1-B73 and Su1-RC types. Differences between groups were assessed using a two-tailed unpaired t-test.
