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: Cold stress inhibits tomato seed germination, but pretreatment with exogenous glycine betaine (GB) alleviates this inhibition and enhances the germination rate and viability of tomato seeds at low temperatures. GB positively regulates gibberellin content and negatively regulates abscisic acid content, while up-regulating the expression of the amylase gene to reduce starch content in the seeds. GB also up-regulates genes involved in reactive oxygen species scavenging systems, leading to lower levels of malondialdehyde and hydrogen peroxide and elevated levels of proline, peroxidase, superoxide dismutase, and catalase.

Summary: The research demonstrated that grafting and rootstock seed treatment can significantly enhance tomato plant growth, yield, and fruit quality. The GS hybrid rootstock is more effective in mitigating cold stress, especially when inoculated with Streptomyces griseus. This treatment not only increases total yield per plant but also leads to higher levels of GA3 and mineral content in leaves.

Summary: The cry1a mutant in tomato showed reduced root biomass and length, higher tissue malondialdehyde concentrations, and increased leaf relative water content (RWC) under water deficit conditions. Grafted plants exhibited shoot and root biomass accumulation mainly determined by scion genotype, with cry1a rootstocks increasing RWC and WT rootstocks maintaining photosynthesis of cry1a scions in drying soil. Manipulating tomato CRY1a may enhance plant drought tolerance by altering leaf pigmentation and gas exchange during soil drying via local and long-distance effects.

Summary: Previous studies have shown that 5-aminolevulinic acid (ALA) and abscisic acid (ABA) can enhance photosynthesis and mitigate damage from adversity. This experiment aimed to investigate the effects of ALA and ABA on iron utilization and chlorophyll synthesis in tomato seedlings under low-temperature stress. The results demonstrated that exogenous ALA and ABA increased iron accumulation, chlorophyll synthesis, and resistance to low-temperature stress in tomato seedlings. ABA may crosstalk with ALA to regulate chlorophyll synthesis and iron accumulation, thereby improving the photochemical efficiency and low temperature resistance of tomatoes.

Summary: The plant cryptochrome's involvement in water deficit responses has been highlighted, with the role of tomato cry1a gene in blue light-dependent modulation of these responses not fully understood. The study showed cry1a's regulation of growth under nonstress conditions and its role in reducing oxidative damage and proline accumulation under osmotic stress. Manipulation of CRY1a gene could be a potential target for developing drought-tolerant tomato varieties, although further investigation is needed for complete understanding.

Summary: The overuse of pesticides has caused serious global concerns for food safety and environmental pollution. This study reveals that exogenous melatonin treatment can significantly reduce the residue of chlorothalonil in tomato leaves, while inhibition of endogenous melatonin accumulation increases the residue. Furthermore, melatonin treatment improves photosynthesis and antioxidant enzyme activity in tomato leaves. The reduction of pesticide residue is mediated by H2O2 signaling in an apoplastic manner.

Summary: Research shows that high concentrations of carbon dioxide can lead to increased accumulation of melatonin in tomato leaves, and this response is conserved in many plant species. Manipulating the levels of melatonin affects the accumulation of sugar and starch in tomato leaves, as well as the expression of chloroplast and nuclear-encoded photosynthetic genes. Furthermore, melatonin plays a crucial role in enhancing plant tolerance to heat stress, regulating reactive oxygen species, redox homeostasis, cellular protein protection, and phytohormone metabolism.

Summary: This study aimed to analyze the specific mechanism of cold tolerance in a wild tomato species (Solanum habrochaites) by studying its physiology, transcriptomics, and lipidomics after exposure to cold stress. The results showed that the stability of cell membrane structure and function, upregulation of lipocalin genes and fatty acid desaturase genes, and changes in lipid levels were associated with cold tolerance in S. habrochaites. Additionally, high phosphoinositide content and ATP production via β-oxidation of fatty acids were also identified as factors contributing to cold tolerance. This study provides important insights into the molecular mechanism of cold resistance in tomato.

Summary: Catechins, particularly EGCG, are important secondary metabolites found in tea plants. The synthesis of catechins is affected by various environmental stresses, and their accumulation is closely related to plant stress tolerance. Additionally, exogenous catechin application has been shown to enhance various aspects of plant growth and development under perturbed conditions. However, high concentrations of catechins can be phytotoxic. This article reviews the biological functions of catechins, particularly EGCG, in plants and discusses their roles in plant adaptation to variable environments as well as their effects on plant growth and adaptation in other plant species. Overall, catechins play a critical role in plant environmental adaptability and immune response, and their properties can be utilized to enhance crop production in an environmentally friendly manner.

Summary: Chromium (Cr) is a toxic element that harms all forms of life, including plants. Industrial discharges and mining contribute to Cr release into the soil environment, leading to reduced crop yield and quality. Arbuscular mycorrhizal fungi (AMF) form mutualistic symbiotic relationships with land plants, enhancing plant resilience to Cr stress and aiding in nutrient acquisition. AMF symbiosis has promising prospects in agricultural production, bioremediation, and ecological restoration in Cr-polluted soils.

Summary: Cold stress affects tomato flower organ abscission and fruit setting rate. Auxin is a key hormone that affects floral organ abscission, and under low temperature stress, its synthesis genes increase in stamens but decrease in pistils. Low temperature treatment also decreases pollen vigor and germination rate, leading to reduced fruit setting rate in tomato.

Summary: Chromium is a toxic heavy metal for animals and plants. The multifunctional signaling molecule melatonin can confer plant tolerance to chromium stress by inducing the accumulation of anthocyanin, a secondary metabolite. Melatonin increases both endogenous and exogenous anthocyanin content, alleviates chromium phytotoxicity, and reduces chromium accumulation in roots and leaves. Suppression of anthocyanin biosynthesis compromises melatonin-induced anthocyanin accumulation and alleviation of chromium phytotoxicity, suggesting that anthocyanin acts downstream of melatonin and is essential for melatonin-induced chromium stress tolerance in tomato plants.

Summary: Global climate change has led to an increase in extreme weather events and non-biological stress on plants. Anthocyanins, as natural pigments, play a vital role in helping plants cope with environmental stress. However, the synthesis and stability of anthocyanins are influenced by external factors. This review explores the regulatory mechanisms of anthocyanin synthesis, the effects of environmental factors on anthocyanin production, and the role of anthocyanins in plants' response to various environmental stressors.
