Special Issue Information
Dear Colleagues,
The Triticeae tribe (Poaceae), encompassing staple crops such as wheat (Triticum aestivum), barley (Hordeum vulgare), and rye (Secale cereale), accounts for over 30% of global calorie intake. Its wild relatives (e.g., Aegilops, Thinopyrum) represent invaluable genetic reservoirs for enhancing disease resistance, stress tolerance, and yield-related traits. However, the evolutionary relationships within this tribe remain complex and inadequately understood, hindering the systematic exploitation of its genetic resources. Recent advances in high-throughput sequencing, phylogenomics, and cytogenetic technologies provide unprecedented tools to decode Triticeae’s evolutionary history and translate these insights into breeding innovations. This Special Issue, titled ‘Biosystematics and Breeding Application in Triticeae Species’, seeks to bridge the gap between evolutionary biology and applied agricultural research, fostering interdisciplinary approaches to harness the tribe’s potential for sustainable crop improvement.
Key challenges include chromosomal mismatches in alien gene introgression, linkage drag, and insufficient genomic frameworks for germplasm prioritization. Climate change and pathogen evolution further underscore the urgency to diversify genetic resources. This Special Issue invites original research, reviews, and methodological perspectives that advance our understanding of Triticeae biosystematics and its practical applications. Topics of interest include, but are not limited to:
- Phylogenetic and population genomic analyses of Triticeae species.
- Strategies for the introgression and utilization of alien germplasm in wheat breeding.
- High-throughput identification, functional validation, and comprehensive omics analyses of elite alien genes.
- Genomic and cytogenetic tools for tracing chromosomal evolution, recombination hotspots, and structural variations.
- Sustainable strategies for conserving and exploiting Triticeae genetic resources.
- Successful examples of trait transfer from wild Triticeae species to cultivated wheat, with emphasis on field performance and stability.

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. Plants is an international peer-reviewed open access semimonthly 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 2700 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.
