Summary: In this study, all four isoforms of CsGolS in cucumber were found to be upregulated by different abiotic stresses. Further investigation revealed that CsGolS1 plays double roles in both assimilate loading and stress response in minor veins, which could improve assimilate transport under adverse conditions. Overexpression of CsGolS1 under cold stress enhanced assimilate translocation efficiency and accelerated growth rates of sink leaves, fruits, and whole plants. These findings demonstrate an unknown response to adverse environments and provide a potential biotechnological strategy to improve stress resistance in cucumber.

Summary: In this study, GC-MS combined with PCA and PLS-DA were used to analyze the metabolites in cucumber xylem and phloem sap under different phosphorus stress. Differential metabolites and key metabolic pathways were screened, providing biochemical information for the metabolic response and regulation strategies of cucumber xylem and phloem under phosphorus stress.

Summary: This study explored the plant response mechanism of cucumber seedlings to low temperature stress and the role of exogenous nitric oxide (NO) in mitigating low temperature stress. The results showed that low temperature stress regulates the transcription levels of genes related to cell cycle, photosynthesis, lignin synthesis, etc. Exogenous NO improves the low temperature tolerance of cucumber by modulating the transcription of genes related to phenylalanine metabolism, plant hormone signal transduction, cell cycle, etc. The study also identified transcription factors and their target genes associated with response to NO and low temperature stress.

Summary: This study demonstrates that melatonin promotes seed germination under low temperature stress by decreasing ABA content and increasing the GA/ABA ratio. The transcriptional regulation of ABA signaling genes by melatonin during cucumber seed germination under low temperature stress is significant.

Summary: Cucumber plants have two distinct phloem systems, the fascicular phloem (FP) and extrafascicular phloem (EFP), which should be distinguished for accurate research. The EFP was identified at various levels using specific antibodies and microscopy, showing different anatomical features and behaviors compared to the FP.

Summary: Photosynthetic active radiation (PAR) refers to photons between 400 and 700 nm, which drive photosynthesis and provide carbohydrates for plant metabolism and development. Far-red radiation (FR, 701-750 nm) is not included in PAR, but including FR in the light spectrum can enhance biomass production and resource-use efficiency.

Summary: Sugars are necessary for the growth and development of cucumber plants. CsAGA2, an alkaline alpha-galactosidase 2 gene, plays a key role in cucumber fruit development through the transportation of sugars in the vascular bundle. CsAGA2 expression increases gradually during fruit development, especially in the fruit vasculature. Downregulation of CsAGA2 leads to delayed fruit growth, while overexpression results in bigger fruits. Genes related to sugar metabolism, cell wall metabolism, and hormone signaling are downregulated in CsAGA2-RNAi plants. CsAGA2 also has a negative feedback regulation on source leaves. These findings suggest that CsAGA2 is essential for cucumber fruit set and development through mediation of sugar communication.

Summary: This study reveals the crucial role of CsIVP in enhancing the resistance of cucumber plants to nitrogen deficiency and high-temperature stress. CsIVP negatively regulates certain genes involved in nitrogen uptake and transport, playing a significant role under low-nitrogen conditions. Furthermore, CsIVP negatively mediates high-temperature responses by interacting with key regulatory factors.

Summary: Plants synthesize a group of compounds called raffinose family of oligosaccharides (RFOs) for their growth, metabolism, and stress tolerance. RFOs are carbohydrate reserves in plants and play important roles in seed germination and stress tolerance. However, an excess of RFOs in edible parts of legume plants causes flatulence in humans and monogastric animals, making it challenging to manipulate RFO levels. This review provides in-depth knowledge of RFOs distribution, physiological function, genetic regulation, and strategies to reduce RFOs for sustainable and nutritious food production.

Summary: This study identified a gene, CsSGR, associated with low-temperature tolerance in cucumber through genome-wide association study. Knockout mutants of CsSGR showed enhanced low-temperature tolerance and increased chlorophyll content. The CsSGR gene is regulated by the CsCBF1 transcription factor. Different haplotypes of CsSGR have different roles in chlorophyll degradation.

Summary: This study investigates the influence of melatonin on the photosystems of cucumber leaves under low temperature stress. The results show that moderate concentrations of melatonin have a positive effect on the growth of low temperature-stressed cucumber seedlings and improve the performance of active photosystem II and electron transport. Melatonin also affects the activity of photosystem I. However, high concentrations of melatonin have a negative effect on regulating low temperature tolerance in cucumber.

Summary: Trehalose-6-phosphate synthase (TPS) is a key enzyme in the synthesis of trehalose, which plays an important role in plant growth and resistance to abiotic stress. In this study, the function of CaTPS1 in response to cold and salt stresses in pepper was investigated. Silencing of CaTPS1 resulted in significant changes in the expressions of CaTPS1, plant morphology, and various physiological indices. The results indicated that CaTPS1 is involved in the response to cold and salt stresses in pepper.

Summary: This study investigated the use of the RE (radicle emergence) test to estimate the seedling emergence and quality of hybrid cucumber seeds under low temperature conditions, high salt conditions, and a combination of the two. The results showed that both stress environments and their combination reduced seedling emergence and quality. The RE values were significantly correlated with seedling emergence and quality, with the RE 24 h showing the highest correlation coefficient.
