Although heterosis, or hybrid vigor, is widely exploited in agriculture, a complete description
of its molecular underpinnings has remained elusive despite extensive investigation. It …

Nearly 100 genes and functional polymorphisms underlying natural variation in plant
development and physiology have been identified. In crop plants, these include genes …

Heterosis refers to the phenomenon that progeny of diverse varieties of a species or crosses
between species exhibit greater biomass, speed of development, and fertility than both …

Heterosis is a fundamental biological phenomenon characterized by the superior
performance of a hybrid over its parents in many traits, but the underlying molecular basis …

Recent advances in plant genomics and molecular biology have revolutionized our
understanding of plant genetics, providing new opportunities for more efficient and …

Intraspecific hybrids between the Arabidopsis thaliana accessions C24 and Landsberg
erecta have strong heterosis. The reciprocal hybrids show a decreased level of 24-nt small …

Heterosis has historically been exploited in plants; however, its underlying genetic
mechanisms and molecular basis remain elusive. In recent years, due to advances in …

Abstract Background Maize (Zea mays) is a globally produced crop with broad genetic and
phenotypic variation. New tools that improve our understanding of the genetic basis of …

The main objective in this research was the genetic analysis of heterosis in rapeseed at the
QTL level. A linkage map comprising 235 SSR and 144 AFLP markers covering 2045 cM …

Background Heterosis describes the superior phenotypes observed in hybrids relative to
their inbred parents. Maize is a model system for studying heterosis due to the high levels of …
