Special Issue Information
Dear Colleagues,
Meat production traits (growth rate, feed efficiency, carcass yield) and meat quality traits (intramuscular fat content, tenderness, water-holding capacity) represent the most economically critical characteristics in modern pig breeding. Despite advancements in porcine genomics starting in the early 20th century, the translation of genetic discoveries into practical breeding tools remains limited, with only a handful of major genes effectively utilized. This Special Issue seeks to bridge this gap by elucidating the molecular mechanisms underlying these traits and developing next-generation breeding technologies.
This Special Issue focuses on the following content:
Genetic and Epigenetic Mechanisms
(1) The identification of novel candidate genes regulating myogenesis, adipogenesis, and muscle fiber composition through GWAS and QTL mapping.
(2) Non-coding RNAs and epigenetic modifications (DNA methylation, histone acetylation) in meat quality regulation.
Advanced Breeding Technologies
(1) Marker-Assisted Selection (MAS) Optimization: High-density SNP panels targeting causal mutations for meat traits.
The integration of pleiotropic markers for multi-trait selection.
(2) Genomic Selection (GS) Algorithms: Machine learning-enhanced genomic prediction. Single-step genomic evaluation (ssGBLUP) for commercial herds.
(3) Gene Editing Applications: CRISPR-Cas9, epigenetic editing.
Multi-Omics Integration
Transcriptome–proteome–metabolome networks in muscle development.
Single cell RNA sequencing and spatial transcriptome sequencing of pig tissues to reveal specific physiological regulatory pathways.

Manuscript Submission Information
Manuscripts should be submitted online at www.mdpi.com by registering and logging in to this website. Once you are registered, click here to go to the submission form. Manuscripts can be submitted until the deadline. All submissions that pass pre-check are peer-reviewed. Accepted papers will be published continuously in the journal (as soon as accepted) and will be listed together on the special issue website. Research articles, review articles as well as short communications are invited. For planned papers, a title and short abstract (about 100 words) can be sent to the Editorial Office for announcement on this website.
Submitted manuscripts should not have been published previously, nor be under consideration for publication elsewhere (except conference proceedings papers). All manuscripts are thoroughly refereed through a single-blind peer-review process. A guide for authors and other relevant information for submission of manuscripts is available on the Instructions for Authors page. Genes is an international peer-reviewed open access monthly journal published by MDPI.
Please visit the Instructions for Authors page before submitting a manuscript. The Article Processing Charge (APC) for publication in this open access journal is 2600 CHF (Swiss Francs). Submitted papers should be well formatted and use good English. Authors may use MDPI's English editing service prior to publication or during author revisions.
