PRJDB2778 Comparison of gene expression pattern between the hybrid and its parents Heterosis describes the superior performance of heterozygous hybrid plants over their homozygous parental inbred lines. Despite the rediscovery of this phenomenon a century ago, the molecular basis of heterosis remains unknown. To reveal patterns of gene expression that may be associated with heterosis, we analyzed gene expression profiles of the rice hybrids and the parents by RNA-Seq. Profiling gene expression in the rice hybrid and its parents none provided
