Heterosis Is Prevalent for Multiple Traits in Diverse Maize Germplasm

PLoS ONE, 2009
BackgroundHeterosis 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 yield heterosis and commercial use of hybrids.MethodsThe inbred lines ...

Additive and Partially Dominant Effects from Genomic Variation Contribute to Rice Heterosis [PDF]

Advanced Science
Heterosis, or hybrid vigor, describes the superior performance of F1 hybrids relative to their parents. Despite its significant importance in crop breeding, the molecular mechanisms underlying heterosis remain debated, mainly attributable to ...

The Pitfalls of Heterosis Coefficients [PDF]

Plants, 2020
Heterosis (hybrid vigour) is a universal phenomenon of crucial agro-economic and evolutionary importance. We show that the most common heterosis coefficients do not properly measure deviation from additivity because they include both a component ...

Heterosis [PDF]

The Plant Cell, 2010
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 parents. Various models have been posited to explain heterosis, including dominance, overdominance, and pseudo-overdominance.

The effect of sex phytoregulators on cucumber productivity

Овощи России, 2023
Relevance. Gender phytoregulators occupy an important place in the seed production of parental forms of cucumber, they allow you to shift the sex of the plant in the right direction, increase the intensity of selection, obtain purely female lines, and ...

Genome-wide association and genomic prediction for resistance to southern corn rust in DH and testcross populations

Frontiers in Plant Science, 2023
Southern corn rust (SCR), caused by Puccinia polysora Underw, is a destructive disease that can severely reduce grain yield in maize (Zea mays L.). Owing to P. polysora being multi-racial, it is very important to explore more resistance genes and develop

Large-scale genomic and transcriptomic profiles of rice hybrids reveal a core mechanism underlying heterosis

Genome Biology, 2022
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 hybrids from crosses between two testers and 265 rice varieties from a mini ...

Heterosis in plants [PDF]

Current Biology, 2018
Heterosis, also known as 'hybrid vigor', is a well-known phenomenon whereby hybrid offspring resulting from cross pollination exhibit greater vigor than either parent. Here, Hochholdinger and Baldauf provide an overview of this fascinating biological phenomenon and what is known about the underlying genetics and mechanisms.

Brassica napus Transcription Factor Bna.A07.WRKY70 Negatively Regulates Leaf Senescence in Arabidopsis thaliana

Plants, 2023
Leaf senescence is the final stage of leaf development and is essential for storage properties and crop productivity. WRKY transcription factors have been revealed to play crucial roles in several biological processes during plant growth and development,
