Special Issue Information

Dear Colleagues,

Horticultural crops are cornerstones of global food security and human nutrition, providing essential vitamins, antioxidants, and bioactive compounds. However, their productivity and quality are increasingly threatened by a cascade of abiotic stresses, such as drought, salinity, extreme temperatures, nutrient imbalances, and UV radiation. These pose unprecedented challenges to sustainable horticulture, particularly in resource-limited and urban agricultural systems.

To address these threats, there is an urgent need to explore innovative strategies and emerging technologies that enhance crop resilience beyond traditional approaches. This Special Issue aims at showcasing cutting-edge research in this domain, ranging from molecular advancements to field-applicable solutions.

We welcome studies on diverse innovations, including, but not limited to, gene editing and synthetic biology for stress-tolerant trait development; nanofertilizers and biostimulants that modulate stress responses; smart sensing technologies for real-time stress monitoring; precision irrigation and controlled environment agriculture (e.g., vertical farming) optimized for stress mitigation; and integrative agronomic practices (e.g., cover cropping and soil microbiome engineering) that enhance systemic resilience. Research investigating the underlying physiological, biochemical, and molecular mechanisms of stress adaptation, as well as interdisciplinary approaches combining engineering, data science, and plant biology, is strongly encouraged.

Such contributions will advance our ability to sustain horticultural productivity under a changing climate, ensuring food security and nutritional quality for future generations. We invite original research articles, reviews, and short communications that drive this critical field forward.

Abstract
The effects of progressive drought stress were examined in four economically important plant species belonging to the Lamiaceae family: catnip (Nepeta cataria L.), lavender (Lavandula angustifolia Mill.), holy basil (Ocimum tenuiflorum L.), and perilla mint (Perilla frutescens (L.) Britton). [...] Read more.
The effects of progressive drought stress were examined in four economically important plant species belonging to the Lamiaceae family: catnip (Nepeta cataria L.), lavender (Lavandula angustifolia Mill.), holy basil (Ocimum tenuiflorum L.), and perilla mint (Perilla frutescens (L.) Britton). Plants were grown in a controlled pot experiment under three soil water capacity levels: 70% (control), 50% (moderate stress), and 30% (severe stress), and the drought stress lasted for 30 days. The study evaluated a comprehensive set of leaf micromorphological parameters, including the density and diameter of glandular trichomes, stomatal density and size, and the thickness of the lamina, mesophyll, epidermis, cuticle, and parenchymal layers. In addition, essential oil (EO) content, total flavonoid content (TFC), and elemental composition were analyzed. Drought responses were strongly species-specific. O. tenuiflorum, P. frutescens, and N. cataria showed high sensitivity characterized by reduced biomass and thinning of leaf tissues. These changes were accompanied by typical xeromorphic adaptations, such as increased stomatal and glandular trichome density, and reduced stomatal size. L. angustifolia exhibited pronounced cuticle thickening, suggesting an effective structural mechanism to minimize water loss. Secondary metabolism also responded differently among species. In some cases, drought shifted metabolic allocation toward flavonoid accumulation at the expense of essential oils, whereas in others, moderate stress promoted the co-accumulation of both compounds. These patterns indicate distinct adaptive strategies linking anatomical plasticity with metabolic regulation. Overall, moderate drought supported adaptive responses, while severe water limitation impaired growth and metabolic production. From a practical perspective, maintaining moderate soil water availability appears critical to optimize both plant performance and the accumulation of valuable secondary metabolites in Lamiaceae species.
