Special Issue Information
Dear Colleagues,
Fruit development in horticultural crops is orchestrated by complex molecular networks. Key phytohormones like auxin, gibberellin, and ethylene regulate cell division and expansion, while transcription factors, such as MADS-box proteins, govern the transition from flower to fruit. Concurrently, plants employ sophisticated mechanisms to counter environmental stresses like drought, salinity, and pathogens. These involve stress-responsive genes, antioxidant systems, and signaling molecules like abscisic acid (ABA) and reactive oxygen species (ROS), which activate protective pathways to maintain cellular homeostasis. Fruit quality—which encompasses flavor, color, texture, and nutritional value—is the integrated outcome of these developmental and stress-response programs. This process requires the precise regulation of metabolic pathways for sugars, acids, pigments (anthocyanins and carotenoids), volatiles, and health-promoting compounds. Crucially, epigenetic modifications and post-transcriptional regulation fine-tune these processes. Understanding these interconnected molecular mechanisms is vital for breeding superior varieties with enhanced resilience, yield, and consumer-desired traits in a changing climate. This Special Issue delves into the molecular symphony of fruit development, exploring how phytohormones and environmental cues orchestrate growth from blossom to harvest. We will also illuminate the sophisticated mechanisms plants employ to build resilience against stress, and how these very processes fundamentally shape the final quality, flavor, nutrition, and appeal of horticultural 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 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. Current Issues in Molecular Biology 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.
