Agronomic traits of OsSYF2 transgenic lines. a The phenotype of ZH11, Ri9 and Ri11 7 d seedings. Bar = 1 cm. b and c Morphology and statistical epidermal cell length of the second leaf sheath at three-leaf stage seedlings. Bar = 40 μm. Data are given as mean ± SD (n = 30). Letters indicate significant differences determined by a LSD test (P < 0.05). Letters showed the significant differences, which was ranked by Least Significant Difference (LSD) test (P < 0.05). d The plant height of ZH11 and OsSYF2 transgenic plants measured at maturity. Error bar means SD, at least 7 plants were calculated. Letters indicate significant differences determined by a LSD test (P < 0.05). e-g The panicle morphology, inflorescence length, and the number of primary branches of ZH11 and OsSYF2 transgenic plants at maturity, respectively. Error bar means SD. At least 10 plants were calculated. Bar = 1 cm. Letters indicate significant differences determined by a LSD test (P < 0.05)
