Abiotic stresses are considered as a significant factor restricting horticultural crop productivity and quality. Drought stress is major environmental constraint among the emerging concerns. Plants have susceptibility to drought stress, resulting in marked decline production during last several decades. The development of effective strategies mitigate essential for sustainable agriculture food security, especially considering continuous growth world population. Several studies suggested that exogenous application phytohormone plants can improve tolerance by activating molecular physiological defense systems. Phytohormone pretreatment potential approach alleviating plants. In addition, melatonin, salicylic acid, jasmonates, strigolactones, brassinosteroids, gamma-aminobutyric acid phytohormones function regulators effects stress. These hormones frequently interact with one another survival drought-stressed environments. To sum up, this review will predominantly elucidate role related mechanisms across various horticulture species.

Melatonin and abscisic acid, as major plant hormones, play important roles in the physiological biochemical activities of crops, but interaction between two under salt stress is not yet clear. This study investigated endogenous levels melatonin acid rice by using exogenous melatonin, their synthetic inhibitors, examined interactions stress. The research results indicate that can improve tolerance. alleviated sensitivity caused deficiency, increased antioxidant enzyme activity content treated with synthesis reduced total reactive oxygen species thiobarbituric substance accumulation. also key photosynthetic enzymes pigments, maintaining parameters gas exchange chlorophyll fluorescence. In summary, effects deficiency on photosynthesis systems improved beneficial for expanding understanding regulation crop

The potential risk for CO2 leakage from carbon capture and storage (CCS) systems has raised significant concerns. While numerous studies have explored how crops respond to elevated soil levels, relatively few examined the impacts on vegetables. Tomatoes (Solanum lycopersicum) are a key vegetable crop, this study sought investigate affects their yield quality. We conducted pot experiments comparing tomatoes grown under control conditions (no added CO2) with those exposed levels (1500 g m−2d−1). Our findings indicate that conditions, overall biomass of tomato plants, average fruit weight, size decreased by 47.42%, 47.65%, 20.2%, respectively. Notably, titratable acid content in increased 27.5%, resulting sourer taste. grades sugar ratio declined leading seriously commercial value loss response levels. This provides more quantitative understanding vegetables like leakage, which is crucial CCS decision-makers comprehend adverse effects leaks agriculture.

ABSTRACT The modern cultivated tomato ( Solanum lycopersicum ) was domesticated from pimpinellifolium native to the Andes Mountains of South America through a “two‐step domestication” process. It introduced Europe in 16th century and later widely worldwide. Since late 19th century, breeders, guided by genetics, breeding science, statistical theory, have improved tomatoes into an important fruit vegetable crop that serves both fresh consumption processing needs, satisfying diverse consumer demands. Over past three decades, advancements molecular technologies, represented marker technology, genome sequencing, editing, significantly transformed paradigms. This article reviews research progress field breeding, encompassing sequencing germplasm resources, identification functional genes for agronomic traits, development key technologies. Based on these advancements, we also discuss major challenges perspectives this field.

ABSTRACT Ubiquitination, a critical post‐translational modification, plays pivotal role in fine tuning the immune responses of plants. The tomato ( Solanum lycopersicum ) suffers significant yield and quality losses caused by devastating pathogen Botrytis cinerea . We have discovered SlRAE1 , gene encoding an E3 ubiquitin ligase, as negative regulator resistance to B. interacts with SlSKP1, component SKP1–Cullin1–F‐box (SCF) complex, modulate protein stability transcription factor SlWRKY1 through 26S proteasome pathway. targets inhibits SlJAZ7 suppressor jasmonic acid (JA) signaling, thereby activating JA‐induced defense system affecting susceptibility enhancement observed knock‐out was reduced when also knocked out, highlighting SlWRKY1's SlRAE1's regulation against Our findings elucidate mechanism suggest that targeting modulating stability, could help develop resistant varieties. These insights broader implications for using gene‐editing technologies enhance crop fungi.

Drought stress is a devastating natural that threatens crop productivity and quality. Mitigating the adverse effects of drought on wheat key object in agriculture. C-repeat binding transcription factor/DROUGHT RESPONSE ELEMENT BINDING FACTOR 1 (CBF/DREB1) factors are well known for their role cold acclimation. However, involvement CBF genes mechanisms underlying function remain poorly understood. In this study, 81 CBFs were identified wheat, which further clustered into four distinct lineages based phylogenetic analysis. Chromosomal localization indicated most dispersed across chromosome 5. We three homoeologous (TaCBF14A, TaCBF14B, TaCBF14D) simultaneously upregulated under RNA-seq According to high expression after stress, TaCBF14B was selected functional Subcellular transcriptional activation activity analysis likely functions as factor involved tolerance. Overexpression Arabidopsis enhanced primary root growth by 13.49% (OE1), 12.56% (OE2), 19.53% (OE3) 200 mM mannitol treatment, 21.65% 16.63% 28.13% 250 treatment compared WT. Meanwhile, water loss rate transgenic lines 56% WT leaves, but only 44%, 50%, 40% OE1, OE2, OE3 lines, respectively. Compared wild type, POD activities significantly increased 42.94%, 29.41%, 62.52%, And Pro 16.33%, 5.18%, 29.09%, respectively, type. Additionally, MDA content reduced 40.53%, 15.81%, 54.36%, Further showed hypersensitive abscisic acid (ABA), exhibited AtABI3. speculate plays an important enhancing summary, our findings provide new insights roles
