Tropical Fruit: Germplasm Conservation, Propagation and Breeding Strategies

Dear Colleagues,

Tropical fruit trees encompass numerous varieties such as bananas, mangoes, lychees, pineapples, and papayas. They hold a critical position in the global agricultural trade and dietary structures, and they also serve as important pillars of the local economy in tropical regions across the world. In recent years, the widespread application of omics technologies like genomics has propelled research in the field of tropical fruit tree molecular biology into a new phase. Researchers have started to focus on the growth and development mechanisms, quality regulation rules, and biological breeding technologies of tropical fruit trees, offering scientific support for industrial upgrading.

This Special Issue focuses on tropical fruit trees, with the aim of collecting relevant research achievements in molecular biology, and we also aim to pay special attention to directions related to the conservation of germplasm resources, efficient propagation, and breeding innovation. Topics of interest include the following: tropical fruit tree genetic transformation and gene editing systems, genomic analysis of excellent germplasm resources, functional gene mining and molecular marker development, functional identification of propagation-related genes, application of population genetics in the conservation of germplasm resources, practice of multi-omics integration in breeding, and molecular mechanisms of fruit development and quality regulation, among others. We aim to provide ideas for solving the major industrial problems faced by tropical fruit tree-producing countries, such as variety degradation, weak stress resistance, and low propagation efficiency.

We sincerely invite agronomists and pomologists to contribute review articles and original research articles to this Special Issue, to share their breakthrough achievements in the fields of tropical fruit tree germplasm resource conservation, efficient propagation, biological breeding, and molecular mechanism research, and to jointly promote the sustainable development of the tropical fruit tree industry.

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. Horticulturae 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 2200 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.
