Relative expression levels of OsCKX2 (a) and growth traits (b, c, d) of representative null, heterozygous and homozygous T1 plants derived from OsCKX2-overexpression line, as analyzed by qRT-PCR. a Total RNA was isolated from the leaves of wild type (WT), null lines (1–4, 1–18), CKX2-overexpression heterozygous (1–28, 1–41) and homozygous (1–6, 1–9) lines. 17S rRNA was used as an internal control for normalization. The expression level of WT was used as a reference. Values presented were mean +/− SD of 3 replicates of cDNA samples. b Growth phenotypes of WT, null lines, CKX2-overexpression heterozygous and homozygous lines. (a) Two-month-old plants. b Three-month-old plants. Agronomic traits analyzed upon harvest were (c) panicle number/plant and (d) total biomass/plant
