Overexpression of OsAK3 increased grain length. a Plant phenotype of NIP, OsAK3-OX9 and OsAK3-OX11 at the mature stage. From left to right are grain size (scale bar, 1 cm) and plant profile (scale bar, 20 cm). b RT-qPCR analysis of OsAK3 expression in two overexpression lines. Data are means ± SD (n = 3). P value compared with the wild type by student’s t test. c Statistical data of plant height. Data are means ± SD (n = 10). P value compared with the wild type by student’s t test. d Statistical data of grain length. Data are means ± SD (n = 30). P value compared with the wild type by student’s t test
