Global warming poses a significant threat to crop production and food security, with maize (Zay mays L.) particularly vulnerable high-temperature stress (HTS). This review explores the detrimental impacts of elevated temperatures on development across various growth stages, analyzed within source–sink framework, particular focus seed setting yield reduction. It provides broad analysis cellular molecular responses HTS, highlighting key roles plant hormone abscisic acid (ABA) signaling, calcium chloroplast, DNA damage repair (DDR) system in maize. HTS disrupts ABA signaling pathways, impairing stomatal regulation reducing water-use efficiency, while orchestrates by activating heat shock proteins other protective mechanisms. Chloroplasts, as central photosynthesis, are sensitive often exhibiting photosystem II chlorophyll degradation. Recent studies also highlight significance DDR system, genes like ZmRAD51C playing crucial maintaining genomic stability during reproductive organ development. under conditions emerges factor contributing reduced set, although precise mechanisms remain be fully elucidated. Furthermore, examines cutting-edge genetic improvement strategies, aimed at developing thermotolerant cultivars. These recent research advances underscore need for further investigation into basis thermotolerance open door future advancements breeding crops.

Seed germination is a critical phase during which plants are particularly sensitive to environmental stresses, especially heat stress, due the high metabolic and physiological activities required for initial growth. Melatonin (MT), key antioxidant, crucial assisting in managing abiotic stresses. While impact of melatonin on stress has been explored other developmental stages or species, this first study specifically focus its role maize seed under stress. The treatment with 50 μM significantly enhanced by improving antioxidant capacity, osmotic regulation, hydrolytic enzyme activity, likely through modulation signaling pathways, thus reducing oxidative damage starch content. Furthermore, application promoted accumulation endogenous gibberellins (GAs) inhibited abscisic acid (ABA) content, thereby maintaining dynamic equilibrium between these phytohormones. Principal component analysis correlation provided deeper insights into overall effects biochemical parameters. Integrated transcriptomic metabolomic revealed that exerted regulatory modulating genes pathways associated defense, responses, plant hormone signal transduction. modulated GA ABA sucrose metabolism, phenylpropanoid biosynthesis, induced strengthening defense mechanisms seeds. alignment qRT-PCR findings data further validated robustness underlying mechanisms. In conclusion, provides novel enhancing offers promising strategy crop tolerance agricultural practices.

When plant biomass is anaerobically digested, seeds may survive the energy production process and contaminate digestate. Hard-seeded (HS), i.e., physically dormant, species were found to be difficult inactivate. Here, we aimed verify this finding from lab-scale experimental reactors (ERs) in a full-scale commercial reactor (CR). In addition, tested seed survival pH-buffered water bath (WB). Seeds exposed CR, ER WB treatments at 42 °C for maximum of 36 days. The viability was checked by measuring germination response tetrazolium staining modeled as function exposure time using dose–response approach. CR killed more effectively than treatments. non-HS reference species, Chenopodium album, completely inactivated all Responses HS ranged complete inactivation insensitivity. most resistant Malva sylvestris. least mainly temperature, while additional mortality factors effective species.
