Special Issue Information

Dear Colleagues,

Horticultural crops are increasingly threatened by climate-driven abiotic stresses (e.g., drought, salinity, temperature extremes) and biotic stresses (e.g., pathogens and pests), endangering global food security and nutritional quality. Recent multi-omics and molecular advances have greatly expanded our understanding of the regulatory networks governing stress perception, signaling, and adaptation in horticultural plants.

This Special Issue, "Advances in Stress Biology of Horticultural Plants," showcases cutting-edge research on the physiological, biochemical, and molecular mechanisms underlying stress tolerance and resistance. Understanding how stresses affect crop cultivation and alter quality traits is key to developing adaptive management strategies. We welcome original research, reviews, and short communications on topics including, but not limited to: stress-responsive gene regulation and signaling networks; phytohormonal crosstalk; epigenetic mechanisms; multi-omics dissection of stress pathways; biostimulant and elicitor applications; cultivation practices for stress mitigation; and biotechnological strategies for enhancing stress resilience.

We invite researchers worldwide to share their latest findings, advancing collective knowledge toward sustainable horticultural production under changing environmental conditions.

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. 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 2400 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.

This study evaluated cold tolerance and selected superior individuals from 100 Zoysia japonica ‘Zenith’ plants. Following pre-cold treatment at 4 °C for 24 h, candidates were screened using electrolyte leakage (EL) with a 10% selection intensity. Selected candidates and cold-sensitive controls were exposed to 0, −5, and −10 °C for 24 h and assessed using visual injury, EL, Evans blue staining, and 3,3′-diaminobenzidine (DAB) staining. Visual injury increased with decreasing temperature but did not clearly distinguish cold tolerance. Individual 11 exhibited the lowest lethal temperature causing 50% injury (LT50) based on both EL (−10.4 °C) and Evans blue staining (−11.0 °C). The two LT50 estimates were strongly correlated (r = 0.996) and concordant (Lin’s concordance correlation coefficient = 0.909). DAB-based recovery analysis showed effective hydrogen peroxide (H2O2) clearance in individuals 5, 11, 21, 23, and 40, with individual 23 exhibiting the lowest reactive oxygen species area under the curve (121.5). A modified Generalized Value Index integrating visual injury, mean LT50, oxidative stress, and recovery slope identified individuals 5, 11, 18, 23, and 30 as superior cold-tolerant selections. Therefore, combining membrane-damage and oxidative-recovery indicators can provide a robust framework for selecting cold-tolerant Z. japonica ‘Zenith’ for field validation and breeding. Full article
