Summary: In this study, the effects of rainfall changes on the photosynthetic characteristics and antioxidant system of Gymnocarpos przewalskii were investigated. Results showed that increased rainfall led to significant increases in the net photosynthetic rate and transpiration rate. Decreased rainfall resulted in limitations in photosynthesis caused by stomatal and non-stomatal factors. Furthermore, reduced rainfall led to decreased chlorophyll content, maximum photochemical efficiency of PSII, and steady-state optical quantum efficiency, as well as increased production of reactive oxygen species. Enhanced antioxidant enzymes helped alleviate the damage to the photosynthetic apparatus. This study improves our understanding of the adaptive strategies of desert plants under future precipitation changes.

Summary: The study found that water deficit significantly inhibited plant growth and photosynthetic activity, but increased water use efficiency and the activity of some antioxidant enzymes. Seed priming with SA increased leaf area, root dry weight, and root/shoot ratio under drought conditions, while soil drench with SA improved CO2 assimilation rate and stomatal conductance in well-irrigated plants.

Summary: Selenium is an essential element for living systems, but becomes toxic at higher concentrations. This study exposed Dunaliella salina cells to different selenium concentrations and found that 50 mg/L selenium had no significant effect on cell growth and selenium accumulation. However, higher selenium levels led to a decrease in photosynthetic efficiency, chlorophyll content, and an increase in reactive oxygen species, proline content, and lipid peroxidation. Superoxide dismutase and catalase played important roles in antioxidative defense. The accumulation of carotenoids varied at different selenium concentrations, and exposure to 200 mg/L selenium resulted in organelle disorganization. Therefore, the selenium-enriched biomass obtained at 50 mg/L could be used for biofortification of food and feed.

Summary: The severity of damage caused by Rhizoctonia solani on tomato plants depends on the taxonomy of the fungal strains. Upregulation of the SOD gene and activation of the corresponding enzyme may be related to a lower level of disease severity. Activating the plant's defense mechanisms could be helpful in disease management.

Summary: Research showed that abaxial leafy supplemental lighting (AB) can enhance net photosynthetic rate and stomatal conductance in tomato plants compared to adaxial leafy supplemental lighting (AD). However, the underlying regulatory mechanisms remain unclear. In this study, transcriptomic and proteomic changes in tomato leaves were assessed under AB and AD, revealing differential expression of 7352 genes and 152 proteins. Significant differences were observed in genes and proteins related to various pathways, including cell processes, metabolism, regulation, genetic information processing, and organismal systems. The upregulation of key genes involved in hormone signaling, light perception, photosynthesis, plant fitness, and fruit ripening explained the positive effects of AB on plant growth and development. qPCR confirmed the upregulation of genes involved in auxin response, gibberellin synthesis, cell cycle regulation, sugar transport, and fruit ripening. These findings contribute to understanding plant light response mechanisms and identifying genes for efficient light energy utilization.

Summary: Full-spectrum light-emitting diodes (LEDs) with specific amber and blue light wavelengths and bandwidths were studied for their effects on tomato growth and production efficiency. Narrow amber light combined with narrow blue light led to the highest fresh mass yield, followed by white LED and a high-pressure sodium lamp. Chlorophyll content increased with the addition of blue light. The findings suggest that precise selection of amber and blue wavelengths can greatly impact tomato growth and development, making narrow-wavelength combination a more energy-efficient option.

Summary: The application of 24-epibrassinolide (EBR) can alleviate the damage caused by lead (Pb) stress in tomato plants. EBR enhances root and leaf structures, improves the functioning of photosynthetic apparatus, and increases biomass accumulation. Moreover, EBR increases antioxidant enzyme activity, improves photosynthetic pigments and electron transport rate, and enhances photosynthesis. These findings are important for understanding and improving the response of plants to pollutant stress.

Summary: The study reveals that regulating CK levels can delay leaf senescence in tomato plants. Overexpression of ipt in the roots can influence leaf aging, while overexpression in source leaves has no effect. An increase in CK can delay leaf senescence, and this signal is primarily transmitted through the stem rather than the roots.

Summary: This study investigated the impacts caused by S. lycopersici infection on the photorespiration of tomato plants. Infected leaves showed a remarkable reduction in photosynthesis and in the pool of photosynthetic pigments. The respiration and photorespiration-to-gross photosynthesis ratio increased in the infected leaves.

Summary: The study revealed that under waterlogging conditions, watermelon cultivar 'YL' exhibited higher expression of ClaAOX, which led to better photosynthesis and less oxidative damage compared to watermelon cultivar 'Zaojia8424'. Additionally, the alleviation of oxidative damage and promotion of photosynthesis in 'YL' were associated with increased levels of ascorbate, higher GSH/GSSG ratio, and enhanced activity of antioxidant enzymes, such as APX and CAT.
