HIGHLIGHTS
- who: Jianyin Xie from the China Agricultural University have published the research: Large-scale genomic and transcriptomic profiles of rice hybrids reveal a core mechanism underlying heterosis, in the Journal: (JOURNAL)
- what: The authors develop sequence and record the phenotypes of 418 hybrids from crosses between two testers and 265 rice varieties from a mini-core collection. The authors show that nonadditive QTLs are more sensitive to the genetic background and environment than additive ones. The authors propose in most cases is not due to heterozygote advantage but homozygote disadvantage under the insufficient genetic background . . .
