Investigation of agronomic characters
To investigate the effect of OsAP79 on rice agronomic characteristics, the plant height (PH), panicle length (PL), tiller number (TN), setting rate (SR), and 1000-grain weight (GWT) of the NIP, OE, and knockout lines were surveyed. As a result PL, SR, and GWT showed no significant differences among the three lines. However, the PH of the OE and knockout lines was significantly less than that of NIP (73.7 cm). Moreover, the TN of the knockout lines was significantly lower than that of NIP, which was significantly lower than that of the OE79 lines (Table 1).
