Special Issue Information

Dear Colleagues,

Horticultural and specialty economic crops are crucial for global agriculture, providing both nutritional security and high-value commodities for pharmaceutical, ornamental, and industrial sectors. Recent advances in genomics and quantitative genetics have revolutionized our ability to decode complex agronomic traits, accelerating precision breeding for yield, stress resilience, and quality enhancement.

Amid escalating challenges such as climate volatility, pathogen evolution, and resource use efficiency demands, integrating multi-omics data with cutting-edge computational tools is critical. This synergy enables us to identify causal genes/networks underlying key traits, optimize genomic selection models, and bridge the gap between genetic discovery and field application.

This Special Issue seeks high-quality contributions that address (but are not limited to) the following:

  • Pan-genome/transcriptome construction for capturing species diversity;
  • Forward/reverse genetics approaches (GWAS, QTL mapping, and CRISPR-based validation);
  • Multi-omics data integration strategies (genomics, phenomics, and metabolomics);
  • Machine learning-driven prediction models for trait dissection and breeding;
  • Database development for germplasm genotype–phenotype associations;
  • Field-to-lab translational studies applying genomic selection in real-world breeding programs.

We particularly welcome submissions that demonstrate interdisciplinary methodologies that connect molecular insights with scalable breeding solutions for understudied specialty crops.

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. 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.

Hygrophila polysperma is a type of amphibious plant that originates from Acanthaceae. Here, we report its first complete chloroplast (cp) genome. The complete cp genome is 146,675 bp in length with 38.3% of GC content. There are 130 genes including 86 protein coding genes, 36 tRNA genes, and 8 rRNA genes in this genome. Simple short sequence (SSR) analysis found 30 SSRs, 24 of which are located in a large single-copy region. Nucleotide diversity identified six most divergent sequences (trns-GCU, psaA-pafI, psaI-pafII, ycf2, rpl32, and ycf1) among 3 close-related species, H. polysperma, H. ringens, and Asteracantha longifolia. A phylogenetic tree among H. polysperma and another 30 related species was constructed based on the common coding sequence of the cp genome and showed that H. polysperma is most closely related to H. ringens (both belong to subtribe Hygrophilinae) and, together, they form a clade that is sister to A. longifolia. This study provides a basis for systemic and evolution studies as well as the development of molecular markers for species identification and genetic breeding. Full article
