Special Issue Information

Dear Colleagues,

As a vital staple crop, wheat (Triticum aestivum L.) feeds billions of people worldwide, supplying essential nutrients such as carbohydrates, proteins, and minerals. However, global climate change, population growth, and increasing demands for high-quality wheat products pose significant challenges to production. Advances in genomics and molecular breeding, including gene editing, genome analysis, and functional studies, provide powerful tools to dissect key agronomic traits such as disease resistance, yield, and stress adaptation.

This Special Issue aims to compile cutting-edge research on wheat genomics and breeding, focusing on gene discovery, genomic diversity, functional analysis, and innovative breeding strategies. We welcome studies utilizing multi-omics, genome-wide association analysis, transgenic approaches, and physiological investigations. Contributions exploring genes and broader genomic applications are encouraged to advance wheat improvement and sustainable agriculture.

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-anonymized 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.

Objectives: Low-temperature stress has become a key factor severely restricting seedling growth in wheat, highlighting the growing importance of research on low-temperature tolerance in wheat. Most previous studies focused on the aboveground organs, and only a minority specifically targeted the roots. Methods: In this study, a recombinant inbred line population derived from a cross between DH118 and Jinmai 919 was used to dissect the genetic regulatory mechanism underlying root growth and development in wheat seedlings under low-temperature conditions. Results: A total of 9 QTLs associated with low-temperature tolerance coefficient were identified; among them, QCi.saw-2B and QCi.saw-5B were validated to be significantly associated with cold tolerance in a natural population including 289 wheat accessions. Moreover, 13 candidate genes from QTL intervals regulating root growth and development under low-temperature stress were further identified based on RNA sequencing. Conclusions: These results provide a foundation for further exploring the regulatory mechanism of root growth and development in wheat under low-temperature stress. Full article
