“…They function within a complex network of phytohormone functions, influencing, and being influenced by, the activity of other hormones. The interplay between melatonin and ABA under abiotic stress conditions is a compelling aspect of this network, warranting detailed exploration for its potential implications in horticulture (Mukherjee, 2018;Lv et al, 2021;Altaf et al, 2023b;Singh and Roychoudhury, 2023).…”

Solanaceous vegetable crops are cultivated and consumed worldwide. However, they often confront diverse abiotic stresses that significantly impair their growth, yield, and overall quality. This review delves into melatonin and abscisic acid (ABA) biosynthesis and their roles in abiotic stress responses. It closely examines the intricate interplay between melatonin and ABA in managing stress within plants, revealing both collaborative and antagonistic effects and elucidating the underlying molecular mechanisms. Melatonin and ABA mutually influence each other’s synthesis, metabolism and that of other plant hormones, a key focus of this study. The study highlights melatonin’s role in aiding stress management through ABA-dependent pathways and key genes in the melatonin-ABA interaction. Specifically, melatonin downregulates ABA synthesis genes and upregulates catabolism genes, leading to reduced ABA levels. It also directly scavenges H2O2, enhancing antioxidant enzyme activities, thereby underscoring their collaborative role in mediating stress responses. Moreover, the interplay between melatonin and ABA plays an essential role in multiple physiological processes of plants, including stomatal behaviors, wax accumulation, delay leaf senescence, seed germination, and seedlings growth, among others. Recognizing these relationships in Solanaceae vegetable crops holds great importance for improving agricultural practices and crop quality. In summary, this review offers a comprehensive overview of recent studies on the melatonin and ABA interplay, serving as a valuable resource for researchers and breeders dedicated to fortifying crop resilience and productivity within challenging environments.

“…Many plants rely on intricate crosstalk between nutrients and hormones, an effective way of coupling nutritional and developmental information and adjusting their growth and senescence (Singh and Roychoudhury, 2023). Sugar and hormones are thought to work synergistically to regulate plant growth, development and environmental responses (Hu et al, 2017).…”

Pinellia ternata, an environmentally sensitive medicinal plant, undergoes leaf senescence twice a year, affecting its development and yield. However, the underlying mechanism of this phenomenon is still largely unexplored. In this study, a typical senescent population model was constructed, and an integrated analysis of transcriptomic and metabolomic profiles of P. ternatawas conducted using obviously different leaf senescence phenotypes in this model. The result showed that two key modules associated with leaf senescence based on weighted correlation network analysis (WGCNA) were key components for leaf senescence. Further analysis revealed that genes in these two modules were mainly enriched in sugar and hormone signaling pathways, respectively. A network of unigenes and metabolisms related to the obtained two pathways revealed that D-arabitol and 2MeScZR played key roles in leaf senescence. Additionally, a total of 130 hub genes were discovered in this network, and they were categorized into three classes based on connectivity. A total of 34 hub genes and 13 metabolites were further analyzed through a pathway map, the potential crosstalk between sugar and hormone metabolisms might be an underlying reason of leaf senescence inP. ternata. These findings address the knowledge gap regarding leaf senescence in P. ternata, providing candidate germplasms for molecular breeding and laying theoretical basis for the realization of finely regulated cultivation in future.

“…19 Multiple factors, including biotic and abiotic stresses, various plant hormones, the modulation of gene expression, and the production of metabolites, collectively influence stomatal aperture. 20,21 Among plant hormones, abscisic acid (ABA) plays dominant roles, particularly in limiting stomatal aperture size under environmental stress. 21 As signaling molecules, ROS can also regulate stomatal aperture, but excessive ROS accumulation may disrupt chloroplasts, resulting in reduced crop yields.…”
