Linum usitatissimum AccD Enhances Seed Fatty Acid Accumulation and Tolerance to Environmental Stresses during Seed Germination in Arabidopsis thaliana

Plants, 2023
Flax (Linum usitatissimum L.), as an important oil-producing crop, is widely distributed throughout the world, and its seeds are rich in polyunsaturated fatty acids (FAs).

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 ...

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 ...

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

Reproductive Isolation due to Divergent Ecological Selection Is Accompanied by Vast Genomic Instability in Experimentally Evolved Yeast Populations

Molecular Ecology, EarlyView.
ABSTRACT Populations evolving independently in divergent environments accumulate genetic differences and potentially evolve reproductive isolation as a by‐product of divergence. The speed and mechanisms underlying this process are difficult to investigate because we rarely get the opportunity to witness them in natural settings, and histories of ...

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.

Eco‐Evolutionary Genomics Reveal Mountain Range‐Specific Adaptation and Intraspecific Variation in Vulnerability to Climate Change of Alpine Endemics

Molecular Ecology, EarlyView.
ABSTRACT Alpine plants restricted to rocky habitats exhibit intraspecific diversification due to range fragmentation during Holocene warming, complicating predictions of their climate vulnerability. A lack of understanding of eco‐evolutionary mechanisms driving their response to climate change results in ineffective conservation efforts. To uncover the

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 and inbreeding depression for yield and its components traits in barley (Hordeum vulgare)

The Indian Journal of Agricultural Sciences, 2020
Heterosis and inbreeding depression was analysed using a set of diallel crosses involving 10 diverse parents (excluding reciprocals). Heterosis over standard parent for grain yield per plant ranged from -9.65–45.45 (%) and -14.78–12.05 (%) under normal ...

Hybridization Drives Trait Integration in Telomere‐To‐Telomere Apocynum Genomes

Plant Biotechnology Journal, EarlyView.
ABSTRACT Hybridization drives plant adaptation, yet its genomic mechanisms in non‐model perennials remain elusive. Apocynum species thrive in extreme saline‐alkaline environments. This study establishes A. pictum (APZ) as a homoploid hybrid of A. venetum (AVX) and A. hendersonii (AHG), exemplifying hybrid‐driven resilience.
