Summary: This study investigated the role of H2O2 in tomato ripening and found that H2O2 participates in this process through its association with the ethylene signaling pathway. The experiments showed that high irradiance treatment enhanced H2O2 production and accelerated fruit ripening. These results may be attributed to changes in the expression of H2O2-related genes and ethylene-related genes.

Summary: Protected cultivation is resource-efficient, but also resource-intensive. This study assessed the effect of different NPK fertilization rates and scheduling approaches on tomato cultivation in Indian sub-tropics. The recommended dose of fertilizer (100% RDF) with specific scheduling was found to be optimum for tomato yield, water use efficiency, and economics under protected conditions.

Summary: The study found that under extreme temperatures, high temperatures have a negative impact on tomato fruit yield, decreasing fruit yield, while low temperatures do not negatively affect plant physiology, with yields similar to controls. Additionally, both high and low temperatures increased the total soluble solids content of the fruits, suggesting that temperature control may be used as a strategy to modulate fruit quality.

Summary: The OsRGLP1 gene was successfully overexpressed in tomato plants using Agrobacterium-mediated transformation, resulting in noticeable morpho-physiological traits, increased SOD activity, and elevated H2O2 levels. Transgenic lines showed higher chlorophyll content and relative water content in leaves, as well as lower electrolytic leakage. Additionally, they exhibited dwarf phenotypic features, radial secondary growth in vascular cambium regions, and increased density and diversity of trichomes. Further exploration is needed to understand the functional aspects of the transgene and its role in stress responses.

Summary: In this study, 18 AHL family genes were identified in the tomato genome, and their involvement in plant development and stress response was investigated. Six AHL members were found to be localized in the nucleus, indicating their importance in early fruit development. The clade A members showed greater responsiveness to heat, drought, cold, and salt stresses compared to clade B members, suggesting their major role in abiotic stress response. Overexpression of SlAHL1 and SlAHL7 in Arabidopsis increased sensitivity to ABA during seed germination and seedling stages, and inhibited seed germination while promoting primary root elongation under salt and drought stresses. This study highlights the importance of clade A SlAHL genes in abiotic stress response.

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: Temperature stress negatively affects fruit set and growth in tomatoes. The localization of auxin in the ovaries and peduncles, which affects fruit set and growth, is disturbed by short-term high-temperature stress. On the other hand, low-temperature stress does not significantly affect fruit set, but causes a delay and recovery of fruit growth.

Summary: Insufficient copper availability can affect the nutritional value, growth, and yield of fruits, especially tomatoes. This study investigates the transcriptomic changes in red ripe tomatoes grown under suboptimal copper conditions, revealing the molecular mechanisms underlying this stress. The research found that copper deficiency activates signals for metal ion transport, cellular redox homeostasis, pyridoxal phosphate binding, and amino acid metabolism, while repressing the response to phosphate starvation in harvested fruit.

Summary: The study demonstrates that melatonin pretreatment significantly enhances the salt tolerance of tomato seedlings by improving root architecture, photosynthetic pigments, and overall growth status under salt stress. It also effectively reduces oxidative stress, inhibiting the accumulation of harmful substances and promoting enzymatic and non-enzymatic antioxidants activities to mitigate salinity-induced damage.

Summary: Chloride (Cl-) and nitrate (NO3-) are closely related anions involved in plant growth. It has been traditionally believed that chloride antagonizes nitrate uptake and accumulation in plants. However, recent studies have shown that chloride nutrition at beneficial macronutrient levels can improve nitrogen use efficiency (NUE) in plants. The underlying biochemical mechanisms of how beneficial chloride nutrition improves NUE are poorly understood.

Summary: The industrial washing of corn grain during its milling generates a residue known as corn steep liquor (CSL), which is rich in nutrients that can promote plant growth. This study examined the effects of two CSL products (CSL-H and CSL-B) on pepper plants when applied through foliar and root application. Both methods increased plant size, with root application being more effective. The CSL products were found to enhance hormone synthesis, CO2 assimilation rate, and amino acid concentrations. Root application of CSL-H also increased the concentrations of specific amino acids. The results suggest that these products stimulate plant growth through hormone regulation and carbon and nitrogen metabolism.
