Comparative transcriptome analysis of inbred lines and contrasting hybrids reveals overdominance mediate early biomass vigor in hybrid cotton

Through genome-wide comparative transcriptome analysis, we strongly predict that overdominance at gene expression level plays a pivotal role in early biomass vigor of hybrids. The combinational contribution of circadian rhythm and other metabolic processes may be controlled vigorous growth in hybrids. Our result provides an important foundation for dissecting molecular mechanisms of biomass vigor in hybrid cotton Overall design: 42 samples, triplicates
