Heterosis (or hybrid vigor) has been widely used in crop seed breeding to improve many key
economic traits. Nevertheless, the genetic and molecular basis of this important …

Increasing wheat yield is a key global challenge to producing sufficient food for a growing
human population. Wheat grain yield can be boosted by exploiting heterosis, the superior …

Utilization of heterosis has greatly increased the productivity of many crops worldwide.
Although tremendous progress has been made in characterizing the genetic basis of …

During evolution, mutations produce new lineages that gradually diverge in sequence and
regulatory properties. Related strains or species can hybridize to produce viable offspring …

Background Heterosis is widely used in agriculture. However, its molecular mechanisms are
still unclear in plants. Here, we develop, sequence, and record the phenotypes of 418 …

Hybrid rice breeding for exploiting hybrid vigor, heterosis, has greatly increased grain yield.
However, the heterosis-related genes associated with rice grain production remain largely …

The ever-growing availability of high-quality genotypes for a multitude of species has
enabled researchers to explore the underlying genetic architecture of complex phenotypes …

The abundance of high-quality genotype and phenotype data for the model organism
Arabidopsis thaliana enables scientists to study the genetic architecture of many complex …

Heterosis is most frequently manifested by the substantially increased vigorous growth of
hybrids compared with their parents. Investigating genomic variations in natural populations …

Darwin spent years investigating the effects of self-fertilization, concluding that “nature
abhors perpetual self-fertilization.” Given that selection purges inbred populations of strongly …
