説明

<p>Offspring with non-parental phenotypes is often observed from biallelic genes in diploid eukaryotic organisms. Heterosis arises from allelic interactions between parental genomes and progeny of intra- or inter-species cross exhibit greater biomass, speed of development, and stress tolerance than parental lines. Although numerous studies have been carried out to understand its genetic and/or molecular basis, the molecular mechanisms underlying heterosis and heterotic gene activity remain elusive. Recent advances in technical innovations for whole-genome/epigenome analyses have accelerated understanding of mechanisms underling heterosis. In this review, we introduce the overview of heterosis and heterotic patterns in Arabidopsis and discuss the correlation between epigenetic/genetic alteration and heterosis.</p>
