Interactions between carbon and nitrogen metabolism are essential for balancing source–sink dynamics in plants. Frequent cold stress disrupts these metabolic processes rice reduces grain yield. Two cultivars (DN428: cold-tolerant; SJ10: cold-sensitive) were subjected to 19 °C low-temperature at full-heading varying lengths of time analyze the effects on leaf metabolism. The objective was track carbon–nitrogen flow identify factors affecting Low-temperature significantly reduced activity nitrate reductase (NR), glutamine synthetase (GS), glutamate synthase (GOGAT), dehydrogenase (GDH), glutamic oxaloacetic transaminase (GOT), pyruvic (GPT), functional leaves compared control. This reduction decreased accumulation, inhibited chlorophyll synthesis, slowed photosynthesis. To preserve intracellular osmotic balance lessen low temperatures, sucrose, fructose, total soluble sugar levels, as well sucrose (SS) phosphate (SPS) activities, surged response stress. However, adenosine diphosphate glucose pyrophosphorylase (AGPase), granule-bound starch (GBSS), (SSS), branching enzyme (SBE). At same time, area vascular bundles phloem, making it difficult transport metabolites grains time. differs from that leaves, with prolonged exposure causing a gradual decrease metabolism-related activities product accumulation within grains. insufficient synthesis precursors skeletons results lower thousand-grain weight seed-setting rates, ultimately contributing yield loss. decline more pronounced inferior superior Compared SJ10, DN428 exhibited higher values across various indicators smaller declines under stress, suggesting enhanced cold-tolerance greater capacity maintain stability.

Effects of drought pretreatment on the morphology traits, biomass, and stoichiometric characteristics of the desert ephemeral plant

Frontiers in Genetics, Год журнала: 2025, Номер 16

Опубликована: Март 20, 2025

Introduction: In the context of climate change, frequency and intensity droughts in arid semi-arid areas have shown a substantially increasing trend, which inevitably affects plant survival growth. However, it is unclear what growth strategies plants subjected to drought pretreatment early life stages adopt when facing subsequent stress. Methods: Here, we conducted field experiment set up two treatments, control pretreatment, investigate effects on survival, phenology, morphology, biomass, stoichiometric characteristics ephemeral Erodium oxyrhinchum Gurbantunggut Desert, China. Results: The results showed that leafing, flowering, fruiting under occurred markedly earlier than treatment by 5.25 ± 1.2 d, 3.13 0.84 4.75 1.63 respectively. history E. decreased 5 1.38 d pretreatment. Drought accelerated seedling mortality, leading faster decline percentage. percentage at full blooming stage was approximately 18.59%, 5.19% higher treatment. addition, positive correlation observed between morphological traits individual increased biomass reproductive output. For example, 1.41 times during stage, indicating exhibited an overcompensation effect. Finally, from perspective characteristics, require more phosphorus enhance their resistance severe drought. Conclusion: This study provides novel insights for conservation restoration desert ecosystems change.

Silicon’s defensive role against biotic and abiotic stress: a review

Phosphorus, sulfur, and silicon and the related elements, Год журнала: 2025, Номер unknown, С. 1 - 20

Опубликована: Март 24, 2025

Silicon enhances developmental processes and controls the enzymatic functional properties of plants. It is considered a quasi-element in earth's crust, absorbed translocated to aerial parts through transpiration. reduces various plant stress conditions, with plants displaying both direct indirect defensive mechanisms. Indirect defense involves release volatiles that attract pathogen's natural enemies, while morphological, biochemical, molecular impediments constitute defense. Both mechanisms are strengthened by silicon treatment. polymerization silicic acid intercellular spaces beneath cuticles as phytoliths, establishing against pathogens. activates multiple pathways, encouraging accumulation supplementary metabolites, thereby enhancing defenses abiotic biotic challenges. also contributes significantly mediated phytohormones. Studies show positively affects during severe modifying several metabolites. Phytohormones essential crop plants' biochemical physiological functions under unfavorable environmental circumstances. Frontline phytohormones, such auxin, cytokinin, ethylene, gibberellin, salicylic acid, abscisic brassinosteroids, jasmonic regulate tolerance pathways intrinsically linked silicon. This review highlights silicon's functionality stresses.
