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 ...

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 ...

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 ...

Dispersed emergence and protracted domestication of polyploid wheat uncovered by mosaic ancestral haploblock inference

Nature Communications, 2022
The contribution of ancient haplotypes to domestication is largely unknown. Here, the authors develop an ancestral genomic haploblock dissection method to generate a mosaic pan-ancestry genomic map and reveal that the domesticated polyploidy wheat ...

Transcriptomics reveals a core transcriptional network of K-type cytoplasmic male sterility microspore abortion in wheat (Triticum aestivum L.)

BMC Plant Biology, 2023
Background Cytoplasmic male sterility (CMS) plays a crucial role in hybrid production. K-type CMS, a cytoplasmic male sterile line of wheat with the cytoplasms of Aegilops kotschyi, is widely used due to its excellent characteristics of agronomic ...
