Special Issue Information

Dear Colleagues,

This Special Issue, “The 15th Anniversary of Genes: Feature Papers in the Animal Genetics and Genomics Section”, aims to bring together high-quality review articles or research articles on all aspects of the most recent advances in interdisciplinary animal genetics fields and to share knowledge between scientists and professionals. It is dedicated to recent advances in the research area of genomics and genetic and comprises a selection of exclusive papers from the Editorial Board Members (EBMs) of the “Animal Genetics and Genomics” Section, as well as invited papers from relevant experts. We also welcome senior experts in the field to make contributions to this Special Issue. We aim to present our Special Issue as an attractive open access publishing platform for genomics and genetic research.

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.

Splicing regulatory sequences are cornerstones for exon recognition. Mutations that modify them can severely compromise mRNA maturation and protein production. A wide range of mutations, including SNPs and InDels, can influence splicing regulatory signals either directly (e.g., altering canonical donor and acceptor dinucleotides) or indirectly (e.g., creating cryptic splice sites). CSN1S1 and CSN1S2 genes encode for the two main milk proteins, αs1 and αs2 caseins, respectively. They represent a remarkable and unique example of the possibilities for alternative splicing of individual genes, both due to the high number of alternative splices identified to date and for recognized allele-specific splicing events. To date, at least 13 alleles of CSN1S1 originating from mutations that affect canonical splice sites have been described in Bos taurus (CSN1S1 A, A1, and H), Ovis aries (E, H, and I), Capra hircus (D and G), Bubalus bubalis (E, F) and Camelidae (A, C, and D). Similarly, allele-specific splicing events have been described at the CSN1S2 locus in B. taurus. (CSN1S2 D), C. hircus (CSN1S2 D), B. bubalis (CSN1S2 B, B1, and B2), Equus asinus (CSN1S2 I B), and Camelidae. This review highlights that mutations affecting canonical splice sites, particularly donor sites, are significant sources of genetic variation impacting the casein production of the main dairy livestock species. Currently, a key limitation on this topic is the lack of detailed functional and proteomic studies. Future research should leverage advanced omics technologies like long-read transcriptomics and allele-resolved RNA sequencing to characterize these splicing mechanisms, guiding precision breeding strategies.
