Summary: Light, especially green light, plays a significant role in enhancing drought tolerance in tomato plants through regulating stomatal aperture and ABA accumulation. The molecular responses of tomato plants under monochromatic red, blue, and green light spectrum with drought stress revealed the involvement of various genes related to plant hormone signal transduction, phototransduction, and calcium signaling pathway. Transcription factors like HY5, WRKY46, and WRKY81 were identified as key regulators in green light-induced drought responses.

Summary: This study reveals the negative regulatory role of SlHB8 in drought resistance of tomato plants. The slhb8 plants exhibit a robust resistant phenotype under drought stress conditions, with significant stomatal closure to effectively mitigate the adverse effects of drought on photosynthetic efficiency. Furthermore, slhb8 plants show increased antioxidant enzyme activity, decreased oxidative damage, and alleviated photoinhibition and chloroplast damage caused by drought stress. SlHB8 regulates the expression of genes related to photosynthesis and stress signal transduction in response to drought stress. Additionally, slhb8 plants exhibit enhanced water absorption capacity and upregulated expression of aquaporin genes.

Summary: We found that drought stress delays the initiation of photosynthesis and exacerbates the loss of carbon gain under fluctuating light in tomato seedlings. Additionally, drought stress aggravates the over-reduction of photosystem I and suppresses the photoprotection of photosystem I. However, drought stress also enhances relative cyclic electron flow, which partially compensates for restricted CO2 fixation and promotes the photoprotection of photosystem I.

Summary: GhMYB44 gene plays a crucial role in plant response to abiotic stress, but its function in cotton is not well understood. In this study, GhMYB44 was induced by drought and ABA treatment in cotton. Silencing GhMYB44 resulted in physiological changes, including increased malondialdehyde content and decreased SOD activity. The silenced plants also exhibited increased stomatal aperture, water loss rate, and decreased drought tolerance.

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: 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 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: Cadmium (Cd) pollution poses a serious threat to crop production. This study investigated the hormonal regulation of phytochelatin (PC) synthesis and the role of melatonin in enhancing plant resistance to Cd stress in tomato. Results showed that Cd stress decreased chlorophyll content and CO2 assimilation rate, but increased Cd, H2O2, and MDA accumulation in the shoot, particularly in PCs deficient plants. Exogenous melatonin treatment increased endogenous melatonin and PC contents, alleviated oxidative stress, and improved osmotic balance and nutrient absorption. These findings provide insights into the mechanism of melatonin-regulated PC synthesis and its potential to enhance plant resistance to toxic metal stress.

Summary: Plants respond to elevated CO2 (eCO2) by changing the synthesis and signaling of salicylic acid (SA) and jasmonic acid (JA), resulting in variations in plant defense responses to pathogens. eCO2 typically enhances SA signaling and suppresses JA pathway, leading to the suppression of biotrophic and hemibiotrophic pathogen diseases but the enhancement of necrotrophic fungal pathogen diseases. The modulation of antagonism between SA and JA under eCO2 affects plant immunity to different pathogens. This review focuses on recent advances in SA and JA signaling pathways in plant defense and their effects on plant immune responses to pathogens under eCO2, emphasizing the importance of understanding these interactions in the context of climate change.

Summary: Due to climate change, rapid industrialization, and increased use of agrochemicals, abiotic stress has become a serious problem in global agriculture. Anthocyanins, an important plant pigment, provide protection for plants under stress and are used as sunscreens, antioxidants, and metal chelators. Plant hormones such as abscisic acid, jasmonic acid, ethylene, and gibberellin play a role in regulating anthocyanin synthesis and can enhance plant stress resistance. Further research is needed to explore the potential of using plant hormones to improve plant stress tolerance in practical crop production.

ROXY19, a plant-specific CC-type glutaredoxin, was found to strongly repress a subset of genes regulated by class II TGA factors through its association with the TPL/TPR family. The ectopic expression of ROXY19 in Arabidopsis plants led to hypersensitivity to xenobiotic chemicals due to the silencing of detoxification pathway genes.
