The black honey bee genome: insights on specific structural elements and a first step towards pangenomes Genet. Sel. Evol. (IF 3.6) Pub Date : 2024-06-28 Sonia E. Eynard, Christophe Klopp, Kamila Canale-Tabet, William Marande, Céline Vandecasteele, Céline Roques, Cécile Donnadieu, Quentin Boone, Bertrand Servin, Alain Vignal
The honey bee reference genome, HAv3.1, was produced from a commercial line sample that was thought to have a largely dominant Apis mellifera ligustica genetic background. Apis mellifera mellifera, often referred to as the black bee, has a separate evolutionary history and is the original type in western and northern Europe. Growing interest in this subspecies for conservation and non-professional

Genome sequence variants affecting complex traits (quantitative trait loci, QTL) are enriched in functional regions of the genome, such as those marked by certain histone modifications. These variants are believed to influence gene expression. However, due to the linkage disequilibrium among nearby variants, pinpointing the precise location of QTL is challenging. We aimed to identify allele-specific

Predicting grass proportion in fresh alfalfa: Grass mixtures using a hand‐held near‐infrared spectrometer Crop Sci. (IF 2.0) Pub Date : 2024-05-06 Rink Tacoma‐Fogal, May Boggess, Jerome. H. Cherney, Mathew Digman, Debbie J. R. Cherney
Technological advancements have made hand‐held near infrared (NIR) spectrometers more affordable and more accurate, creating interest in on‐farm application for forage management. The objective of this study was to evaluate the ability of a hand‐held NIR spectrometer to predict grass percentage within fresh alfalfa (Medicago sativa L.):grass mixtures. Forage samples were collected at a range of maturities

Proteomic characterization of the different stages of seed germination in Cupressus gigantea Seed Sci. Res. (IF 2.1) Pub Date : 2024-05-03 Jianxin Li, Subin Zhang, Pei Lei, Tong-Ju Eh, Yu Zhang, Guangze Jin, Kun Dong, Qijiang Xu, Qiuxiang Luo, Fanjuan Meng
Seed germination is a pivotal period of plant growth and development. This process can be divided into four major stages, swelling absorption, seed coat dehiscence, radicle emergence and radicle elongation. Cupressus gigantea, a tree native to Tibet, China, is characterized by its resistance to stresses such as cold, and drought, and has a high economic and ecological value. Nevertheless, given its

A comparison of procedures for evaluating and selecting alfalfa landrace germplasm for tolerance to salinity Crop Sci. (IF 2.0) Pub Date : 2024-05-03 Luciano Pecetti, Samir Tlahig, Massimo Confalonieri, Mónica V. Cornacchione, Taoufik Hayek, Salvador Prieto Angueira, Paolo Annicchiarico
In arid and semiarid regions, salinity may affect alfalfa (Medicago sativa) productivity and survival due to either cultivation on salt‐affected soils or the use of salinized irrigation water. Exploiting germplasm evolved under salt‐stress conditions offers opportunities for crop tolerance improvement. In the first phase of the current study, four reportedly salt‐tolerant landraces originated from

Estimating genomic relationships of metafounders across and within breeds using maximum likelihood, pseudo-expectation–maximization maximum likelihood and increase of relationships Genet. Sel. Evol. (IF 3.6) Pub Date : 2024-05-02 Andres Legarra, Matias Bermann, Quanshun Mei, Ole F. Christensen
The theory of “metafounders” proposes a unified framework for relationships across base populations within breeds (e.g. unknown parent groups), and base populations across breeds (crosses) together with a sensible compatibility with genomic relationships. Considering metafounders might be advantageous in pedigree best linear unbiased prediction (BLUP) or single-step genomic BLUP. Existing methods to

Redefining and interpreting genomic relationships of metafounders Genet. Sel. Evol. (IF 3.6) Pub Date : 2024-05-02 Andres Legarra, Matias Bermann, Quanshun Mei, Ole F. Christensen
Metafounders are a useful concept to characterize relationships within and across populations, and to help genetic evaluations because they help modelling the means and variances of unknown base population animals. Current definitions of metafounder relationships are sensitive to the choice of reference alleles and have not been compared to their counterparts in population genetics—namely, heterozygosities

Equivalence of variance components between standard and recursive genetic models using LDL′ transformations Genet. Sel. Evol. (IF 3.6) Pub Date : 2024-05-02 Luis Varona, David López-Carbonell, Houssemeddine Srihi, Carlos Hervás-Rivero, Óscar González-Recio, Juan Altarriba
Recursive models are a category of structural equation models that propose a causal relationship between traits. These models are more parameterized than multiple trait models, and they require imposing restrictions on the parameter space to ensure statistical identification. Nevertheless, in certain situations, the likelihood of recursive models and multiple trait models are equivalent. Consequently

Genetic legacy and adaptive signatures: investigating the history, diversity, and selection signatures in Rendena cattle resilient to eighteenth century rinderpest epidemics Genet. Sel. Evol. (IF 3.6) Pub Date : 2024-05-02 Elisa Somenzi, Erika Partel, Mario Barbato, Ana María Chero Osorio, Licia Colli, Niccolò Franceschi, Roberto Mantovani, Fabio Pilla, Matteo Komjanc, Alessandro Achilli, Heidi Christine Hauffe, Paolo Ajmone Marsan
Rendena is a dual-purpose cattle breed, which is primarily found in the Italian Alps and the eastern areas of the Po valley, and recognized for its longevity, fertility, disease resistance and adaptability to steep Alpine pastures. It is categorized as 'vulnerable to extinction' with only 6057 registered animals in 2022, yet no comprehensive analyses of its molecular diversity have been performed to
