Advances in Traits in Animals and Aquatic Species, and Their Improvement Technologies

Dear Colleagues,

The formation and regulation of traits measured on animals and aquatic species are critical, which is affected by genetics, epigenetic modifications, environmental interactions, and technological interventions. Recent advancements in mechanisms and technological innovation provide multidimensional insights for the sustainable development of animal farming and aquaculture industries. Epigenetic mechanisms are increasingly focused on trait regulation; environmental pressures drive innovations in feed and farming practices; and traditional breeding is transitioning toward genome-wide design breeding, especially interdisciplinary collaboration. Environmentally friendly technologies, such as algae-based feeds and oral vaccines, are now applied on an industrial scale. The research had shifted from single genes to a multidimensional analysis. By combining the "genetics + environment + technology" strategy, animal farming and aquaculture can rapidly grow, contributing significantly to global food security and ecological conservation. 

We are pleased to invite you to show your research advances in traits in animals and aquatic species and their improvement technologies, encouraging both fundamental mechanisms and applied innovations.

This Special Issue aims to provide cutting-edge scientific insights and practical solutions for the industry. 

In this Special Issue, original research articles and reviews are welcome. Research areas may include (but are not limited to) the following:

1. Elucidation of the molecular basis of traits.

Mechanisms underlying the formation and variation in traits such as growth, spawning, reproduction, disease resistance, and stress tolerance.

2. Analysis of the genetic foundations of traits

Genomic variations (e.g., SNPs, structural variants), evolutionary mechanisms, and regulatory networks driving traits like growth, reproduction, and stress adaptation.

3. Investigation of interactions between traits and the environment

Relationships between environmental factors (e.g., temperature, pathogens) and developmental processes, including physiological responses to heat stress and host–pathogen dynamics. 

4. Dynamic regulation of traits

Spatiotemporal regulatory processes, such as hormonal and metabolic pathway dynamics, that shape phenotypic outcomes.

5. Epigenetic regulation of traits

Roles of non-coding RNAs, DNA methylation, histone modifications, and other epigenetic mechanisms in trait modulation.

6. Traditional methods for trait improvement

Innovations in feed formulation, farming practices, disease management (e.g., novel therapeutics), and selective breeding strategies.

7. Emerging technologies for trait enhancement

Advanced tools such as gene editing (e.g., CRISPR), nanomaterial-based delivery systems, and novel vector applications.

We look forward to receiving your contributions.

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 250 words) can be sent to the Editorial Office for assessment.

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. International Journal of Molecular Sciences is an international peer-reviewed open access semimonthly journal published by MDPI.

Please visit the Instructions for Authors page before submitting a manuscript. There is an Article Processing Charge (APC) for publication in this open access journal. For details about the APC please see here. 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.
