Maize is very sensitive to salt stress during seed germination and seedling growth periods, which can seriously affect the development of maize industry. In this study, we applied exogenous melatonin (MT) treat seeds seedlings investigate alleviation mechanism damage in maize. Phenotypic analyses showed that 100 µmol/L MT alleviated effects on germination, index vigor were increased compared with treatment. also biomass photosynthesis seedlings, at a concentration µmol/L, root shoot lengths increased, Gs Tr significantly elevated, LWUEint LWUEins decreased. scavenged ROS accumulation, reduced MDA, H2O2, O2- production, antioxidant enzyme activities osmoregulatory substances but too high exacerbated oxidative osmotic stresses. addition, Na+ content K+ leaves roots seedlings. The principal components analysis explained 99.1% total variance first two axes (PC1 PC2), differences between treatment groups along PC1 PC2 obvious. Correlation elucidated correlation indicators. Random forest different treatments had significant percentage (GP), free proline (FP), CAT, leaf intrinsic water use efficiency (LWUEint). Partial least squares photosynthetic parameters pigment played an important role tolerance conclusion, application effectively alleviate negative especially most effective.

Abstract Ring rot, caused by Botryosphaeria dothidea , is an important fungal disease of pear fruit during postharvest storage. Melatonin, as a plant growth regulator, plays role in enhancing the stress resistance fruits. It enhances fruits to ring rot their antioxidant capacity. However, underlying mechanism remains unclear. In this study, we examined effect melatonin on B. . Results showed that did not limit vitro culture. metabolomics and transcriptomics analyses ‘Whangkeumbae’ ( Pyrus pyrifolia ) revealed increased activity enzymes, including peroxidase (POD), superoxide dismutase (SOD), polyphenol oxidase (PPO), activated phenylpropanoid metabolic pathway improve resistance. Furthermore, treatment significantly contents jasmonic acid phlorizin fruit, both which could Jasmonic regulates synthesis can also promote synthesis, ultimately improving rot. summary, interaction between defense response metabolism thereby disease. Our results provide new insights into application

Maize (Zea mays L.) is sensitive to salt stress, especially during seed germination and seedling morphogenesis, which limits maize growth productivity formation. As a novel recognized plant hormone, melatonin (MT) participates in multiple developmental processes mediates biotic/abiotic stress responses, yet the effects of on seedlings remain unclear. Herein, we investigated 150 μM exogenous MT phenotypes physiologic metabolisms three-leaf across eight inbred lines under 180 mM NaCl including parameters, stomatal morphology, photosynthetic metabolisms, antioxidant enzyme activities, reactive oxygen species (ROS). Meanwhile, six gene expression levels controlling activities pigment biosynthesis two materials with contrasting resistance were examined for all treatments explore possible molecular mechanism alleviating injury maize. The results showed that application protected membrane integrity reduced ROS accumulation by activating system leaves their relative conductivity H2O2 level average 20.91% 17.22%, while superoxide dismutase (SOD), peroxidase (POD), catalase (CAT), ascorbate (APX) averaged increased 13.90%, 17.02%, 22.00%, 14.24% alone. improvement size deposition pigments more favorable enhancing photosynthesis when these treated size, chlorophyll content, net rate 11.60%, 19.64%, 27.62%. Additionally, Gene analysis stimulation significantly genes (Zm00001d009990, Zm00001d047479, Zm00001d014848, Zm00001d007234) (Zm00001d011819 Zm00001d017766) stress.

Abstract Melatonin (MT) serves an indispensable function in plant development and their response to abiotic stress. Although numerous drought‐tolerance genes have been ascertained wheat, further investigation into the molecular pathways controlling drought stress tolerance remains necessary. In this investigation, it was observed that MT treatment markedly enhanced resistance wheat by diminishing malondialdehyde (MDA) levels augmenting activity of antioxidant enzymes POD, APX, CAT compared untreated control plants. Transcriptomic analysis disclosed melatonin activated tryptophan metabolism flavonoid biosynthesis pathways. Furthermore, quantitative reverse transcription PCR (qRT‐PCR) outcomes validated expression trends these differentially expressed aligned with transcriptomic data. Metabolomic profiling identified alterations abundance several metabolites, including tryptamine, MT, formylanthranilate, 3‐hydroxyanthranilate, 6‐hydroxymelatonin, naringenin chalcone, astragalin, pinbanksin, caffeoyl quinic acid. Co‐expression suggested various factors—encompassing AP2/ERF‐ERF, WRKY, bZIP, C2H2, bHLH, NAC, MYB—participated across multiple Ultimately, findings highlight exogenous application bolsters wheat's through modulation biosynthesis. These insights provide novel perspectives on frameworks mediating MT's effect pinpointing candidate for potential genetic enhancement programs wheat.
