Large-Scale Analysis of Combining Ability and Heterosis for Development of Hybrid Maize Breeding Strategies Using Diverse Germplasm Resources

open access: yesFrontiers in Plant Science, 2020
Understanding combining ability and heterosis among diverse maize germplasm resources is important for breeding hybrid maize (Zea mays L.). Using 28 temperate and 23 tropical maize inbreds that represent different ecotypes and worldwide diversity of ...

Physio-Morphological Characters of F1 Hybrids of Rice (Oryza sativa L.) in Japonica-Indica Crosses

open access: yesPlant Production Science, 2001
A pot experiment was conducted to study photosynthetic rate in terms of carbon dioxide exchange rate (GER), chlorophyll meter reading (SPAD value) and specific leaf area (SLA) of 12 Fj hybrids from crosses between japonica and indica rice and their ...

Mapping a leaf rust resistance gene LrOft in durum wheat Ofanto and its suppressor SuLrOft in common wheat

open access: yesFrontiers in Plant Science, 2023
Epidemics of leaf rust (caused by the fungal pathogen Puccinia triticina Erikss., Pt) raise concerns regarding sustainability of wheat production. Deployment of resistant cultivars is the most effective and economic strategy for combating this disease ...

Temporal Regulation of the Metabolome and Proteome in Photosynthetic and Photorespiratory Pathways Contributes to Maize Heterosis[OPEN]

open access: yesThe Plant Cell, 2020
Hybrids optimize metabolic abundance through diurnal nonadditive expression of key enzymes in photosynthetic and photorespiratory pathways to enhance photosynthetic efficiency and plant growth.

Hybridization and gene expression: Beyond differentially expressed genes

open access: yesMolecular Ecology, EarlyView.
Abstract Gene expression has a key role in reproductive isolation, and studies of hybrid gene expression have identified mechanisms causing hybrid sterility. Here, we review the evidence for altered gene expression following hybridization and outline the mechanisms shown to contribute to altered gene expression in hybrids. Transgressive gene expression,

Hierarchical additive effects on heterosis in rice (Oryza sativa L.)

open access: yesFrontiers 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.

Assessment of heterosis based on parental genetic distance estimated with SSR and SNP markers in upland cotton (Gossypium hirsutum L.)

open access: yesBMC Genomics, 2020
Background Heterosis has been extensively utilized in different crops and made a significant contribution to global food security. Genetic distance (GD) is one of the valuable criteria for selecting parents in hybrid breeding.

Admixture Increases Genetic Diversity and Adaptive Potential in Australasian Killer Whales

open access: yesMolecular Ecology, EarlyView.
ABSTRACT Admixture is the exchange of genetic variation between differentiated demes, resulting in ancestry within a population coalescing in multiple ancestral source populations. Low‐latitude killer whales (Orcinus orca) populations typically have higher genetic diversity than those in more densely populated, high productivity and high‐latitude ...

A Test of the Long‐Term Efficiency of Genetic Rescue With Drosophila melanogaster

open access: yesMolecular Ecology, EarlyView.
ABSTRACT Genetic rescue is considered a promising but underutilised conservation strategy to mitigate inbreeding depression and restore genetic diversity. Yet, empirical evidence supporting its long‐term efficacy is limited to studies investigating short‐term effects.

Hybridity has a greater effect than paternal genome dosage on heterosis in sugar beet (Beta vulgaris)

open access: yesBMC 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.
