Local Selection Shaped the Diversity of European Maize Landraces

Molecular Ecology, EarlyView.
ABSTRACT The introduction of populations to novel environments can lead to a loss of genetic diversity and the accumulation of deleterious mutations due to selection and demographic changes. We investigate how the recent introduction of maize to Europe shaped the genetic diversity and differentiation of European traditional maize populations and ...

Heterosis analysis for grain yield traits in Maize (Zea mays L.)

Electronic Journal of Plant Breeding, 2018
In the present study 6 inbreds were used as parents to make crosses in all possible cross combination in full diallel fashion to obtain total 30 possible F1 hybrids. These 30 F1’s were subjected to heterosis analysis for midparental, heterobeltiosis and

Comparative transcriptome analysis between inbred and hybrids reveals molecular insights into yield heterosis of upland cotton

BMC Plant Biology, 2020
Utilization of heterosis has greatly improved the productivity of many crops worldwide. Understanding the potential molecular mechanism about how hybridization produces superior yield in upland cotton is critical for efficient breeding programs.

Evolutionary History and Rhizosphere Microbial Community Composition in Domesticated Hops (Humulus lupulus L.)

Molecular Ecology, EarlyView.
ABSTRACT Humulus lupulus L., commonly known as hop, is a perennial crop grown worldwide and is well known for its pharmacological, commercial, and most importantly brewing applications. For hundreds of years, hop has undergone intense artificial selection, with over 250 cultivated varieties being developed worldwide, all displaying differences in key ...

Uncovering the Nanozostera japonica species complex suggests cryptic speciation and underestimated seagrass diversity

New Phytologist, EarlyView.
Summary The importance of marine angiosperms, or seagrasses, as foundation species for marine coastal ecosystems is in marked contrast to their low species number of only 70 described taxa. Seagrass species tend to have very similar overall morphologies dictated by hydrodynamic forces of the ocean environment.

TaTCP6 is required for efficient and balanced utilization of nitrate and phosphorus in wheat

Nature Communications
High crop yields require adequate nutrients, particularly nitrate (N) and phosphorus (P). Identifying regulators for efficient N-P utilization is critical in wheat.

Estimation of heterosis in pearl millet [Pennisetum glaucum (L.)] for yield and quality traits

Electronic Journal of Plant Breeding, 2016
Five CMS lines were crossed with nine testers in a line x tester design to study the extent of heterosis in pearl millet for yield and quality traits. Heterosis was observed in both directions for most of the characters.

'Heterosis' in Drosophila [PDF]

Evolution, 1963
In the course of some experiments with Drosophila melanogaster on the adaptive value of several dominant mutants in competition with their wild-type alleles, an anomalous situation arose with respect to Lobe-2. Further investigation of these results produced an explanation which raises some interesting questions about reports of heterosis in Drosophila.

Theory of Heterosis

Journal of Dairy Science, 1985
Abstract The theory of heterosis is expressed by simple genetic models. Relevant population means are deduced for differences in gene frequencies among populations. Heterosis for the one-locus, two-allele model is a function of the square of the difference in gene frequency multiplied by the dominance deviation.
