Transcriptome profiling of two super hybrid rice provides insights into the genetic basis of heterosis

BMC Plant Biology, 2022
Background Heterosis is a phenomenon that hybrids show superior performance over their parents. The successful utilization of heterosis has greatly improved rice productivity, but the molecular basis of heterosis remains largely unclear.
