Relative expression levels of related genes. T1: differentiation stage of the first bract primordium; T2: differentiation stage of the primary branch primordium; T3: differentiation stage of the secondary branch and spikelet primordium; MOC1: MONOCULM1, LAX1:LAX PANICLE1; SP1: Short Panicle1; GS1;1: Glutamine Synthetase1;1; OFA: optimized nitrogen fertilizer application; TFA: traditional nitrogen fertilizer application; * and ** indicate significant difference of the two nitrogen treatments at 0.05 and 0.01 probability levels, respectively.
