Table 1. Physiological and morphometric measurements of OE lines and single knockout mutants relative to the wild type.

Spikelet fertility, 1,000-grain weight, total tiller count, and total seeds per plant were measured at the whole-plant level (n = 25–50 plants). Area, perimeter, length, width, and length-to-width ratio were measured for individual seeds (n = 700–1,000). Tukey’s test was used for comparing the wild type and mutant lines: *, P < 0.05 and **, P < 0.001.
