Expression of homoeologous molecular systems in wheat alloploids [PDF]
, 1976 Allopolyploidy is widespread in the plant kingdom, where it has been of considerable evolutionary significance. Although the existence of heterotic interactions between the genomes that make up an alloploid have been generally assumed, the precise nature

BMC Plant Biology, 2018 Background The phenomenon of heterosis is critical to plant breeding and agricultural productivity. Heterosis occurs when F1 hybrid offspring display quantitative improvements in traits to levels that do not occur in the parents.

Journal of Integrative Plant Biology, EarlyView.PanGraphRNA is an easy‐to‐use platform that improves RNA‐seq analysis by using graph pangenomes instead of a single reference genome. It increases read alignment accuracy, detects important genes missed by traditional methods, and works across major crops, helping researchers obtain more reliable transcriptome results for diverse plant research and ...

OsLG3 contributing to rice grain length and yield was mined by Ho-LAMap
BMC Biology, 2017 Background Most agronomic traits in rice are complex and polygenic. The identification of quantitative trait loci (QTL) for grain length is an important objective of rice genetic research and breeding programs.

Structural Variations Contribute to Subspeciation and Yield Heterosis in Rice
Plant Biotechnology Journal, EarlyView.ABSTRACT Yield heterosis has been extensively exploited in hybrid breeding, with intersubspecific hybrids often exhibiting the most pronounced effects. However, developing elite hybrids remains a laborious and time‐consuming process. The genetic basis of heterosis has been debated for over a century, hindered largely by the lack of high‐quality genomes.

Effects of outbreeding depression on meristics and bilateral asymmetry in hybrids of spatially separated populations of pink salmon (Oncorhynchus gorbuscha) [PDF]
, 2005 Thesis (M.S.) University of Alaska Fairbanks, 2005Different populations of a species distributed over diverse conditions adapt to their local environments to improve their ability to survive or reproduce. Intraspecific hybridization can alter the locally

Hierarchical additive effects on heterosis in rice (Oryza sativa L.)
Frontiers in Plant Science, 2015 Exploitation of heterosis in crops has contributed greatly to improvement in global food and energy production. In spite of the pervasive importance of heterosis, a complete understanding of its mechanisms has remained elusive.

Dynamics of Gene and Allelic Expression During Modern Hybrid Maize Breeding
Plant Biotechnology Journal, EarlyView.ABSTRACT Maize breeding has greatly improved yield through single‐cross hybrids, but the underlying gene regulatory changes remain unclear. This study analysed transcriptomes of landmark maize hybrids and their parents across developmental stages and planting densities.

Plant Biotechnology Journal, EarlyView.ABSTRACT Male‐sterile systems are pivotal for maize hybrid seed production, yet existing systems are constrained by significant limitations. Here, we identified a novel single‐gene‐controlled recessive genic male sterility (GMS) mutant, defective in filament elongation 1 (def1), which exhibits non‐elongated filaments, unopened glumes, and non‐exserted ...
