Special Issue Information

Dear Colleagues,

Abiotic stresses can significantly impact plant physiology and morphology, affecting various processes like photosynthesis, water metabolism, and nutrient uptake. Drought, waterlogging, extreme temperatures, and salinity are examples of such stresses. These stresses can lead to alterations in gene expression, changes in biosynthetic pathways, the activation of stress-response mechanisms, and also affect the carbon, nitrogen, and phosphorus (C:N:P) balance, ultimately influencing plant growth, development, and productivity. The plant’s response to pathogen infection may also be affected by stress. One of the areas that has been less studied is the effect of combined or complex stresses on plant growth and development. Despite the above, plants may have inherent or develop capabilities that enable them to respond to abiotic stresses and continue growing at a reduced rate or escape the stress impact through early maturity. The Special Issue invites manuscripts that aim to share knowledge on physiological changes in plants in response to various or combinational stresses, and the effect on production or yield parameters.

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.

Understanding intra- and intergenerational adaptive strategies is essential for developing resilient crops. This study investigated these dynamics in Solanum lycopersicum L. cv. Micro-Tom by subjecting parental plants to ultrasound priming and drought stress, followed by drought treatment in the progeny. We introduced the Intergenerational Plasticity Ratio (IPR) as a framework to quantify how stress-response strategies shift across generations. Our results reveal a divergence in adaptation: while parental plants prioritize immediate survival through morphological reductions, the progeny exhibit refined phenological shifts as a cost-effective mechanism. The results suggest that ultrasound may serve as a priming stimulus, preparing internal signaling pathways for heightened stress readiness. These phenotypic shifts suggest that ultrasound-based priming could be explored as a potential non-chemical approach to influence crop resilience. This may allow plants to exhibit adaptive developmental timing in response to specific stressors; however, further research is needed to determine the scalability and stability of these effects across different environments.
