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 ...

What are the consequences of water stress on the development of late postzygotic reproductive isolation in an orchid hybrid zone?

Plant Species Biology, EarlyView.
Hybrids vulnerable to drought may increase postzygotic isolation in hybrid zones. Drought experiments can reveal the influence of climate change on hybrid zones. Crassulacean acid metabolism in parental species and hybrids was negatively affected by drought.

Genome-wide identification and expression analysis of the kinesin gene superfamily suggests roles in response to abiotic stress and fertility of wheat (Triticum aestivum L.)

BMC Genomics
Background Kinesin is a motor for microtubule-based motility. It plays a vital role in plant growth and development. The kinesin superfamily members are known mainly from Arabidopsis.

Divergent selection and genetic introgression shape the genome landscape of heterosis in hybrid rice

Proceedings of the National Academy of Sciences of the United States of America, 2020
Significance The application of heterosis (hybrid vigor) in hybrid rice since the 1970s has tremendously improved rice productivity worldwide. But how breeders construct hybrid parents to obtain hybrid rice heterosis remains unclear.

Rapid design of transgene‐free cabbage with desired anthocyanin contents via HI‐Edit

Journal of Integrative Plant Biology, EarlyView.
The HI‐Edit system combines haploid induction and CRISPR/Cas‐based genome editing to provide a promising way to design crops with desired traits in a rapid, precise and transgene‐free manner. HI‐Edit was applied to produce cabbages with desired anthocyanin contents.

Morphological and metabolomics profiling of intraspecific Arabidopsis hybrids in relation to biomass heterosis

Scientific Reports, 2023
Heterosis contributes greatly to the worldwide agricultural yield. However, the molecular mechanism underlying heterosis remains unclear. This study took advantage of Arabidopsis intraspecific hybrids to identify heterosis-related metabolites.

Negative dominance and dominance-by-dominance epistatic effects reduce grain-yield heterosis in wide crosses in wheat

Science Advances, 2020
Breeding exploits the phenomenon of heterosis for an improved productivity, but negative effects reduce heterosis in wide crosses. The genetics underlying heterosis, the difference in performance of crosses compared with midparents, is hypothesized to ...

TaIRE1‐mediated unconventional splicing of the TabZIP60 mRNA and the miR172 precursor regulates heat stress tolerance in wheat

Journal of Integrative Plant Biology, EarlyView.
In wheat, INOSITOL‐REQUIRING ENZYME 1 (IRE1) helps plants cope with heat stress by regulating unconventional splicing of the mRNA encoding the bZIP transcription factor TabZIP60, which activates heat‐responsive genes, and cleavage of the precursor of the microRNA miR172 during heat stress.

Dissection of two QTL clusters underlying yield-related heterosis in the cabbage founder parent 01–20

Horticultural Plant Journal, 2023
Cabbage has significant heterosis and most commercial cultivars are hybrids. To explore genetic basis of cabbage heterosis and promote cabbage heterosis utilization, we constructed two populations by crossing 100 DH lines derived from a cabbage hybrid 01–
