Perox4 regulates key agronomic traits
We next monitored several key agronomic traits in the perox4mutant to assess its application potential in rice breeding. We compared
agronomic-related traits, including plant height, panicle length, number
of effective panicles, spikelets per panicle, seed setting rate,
thousand-grain weight, grain length, grain width, and grain yield per
plant between parents and knockout lines. The grain width ofperox4 was significantly smaller than WT ZH11 (Fig. 8D and 8E).
Accordingly, the 1,000-grain weight and grain yield per plant were lower
in perox4 than ZH11 (Fig. 8F and Supplemental table 3).
