In crop plants, various environmental stresses affect the balance of carbon, nitrogen, and phosphorus (C:N:P), leading to biochemical physiological alterations reductions in yield. Silicon (Si) is a beneficial element that alleviates plant stress. Most studies involving silicon have focused on responses, such as improvements photosynthetic processes, water use efficiency, antioxidant defense systems. But recent research suggests stressed plants facing either limited or excessive resources (water, light, nutrients, toxic elements), strategically employ Si maintain C:N:P homeostasis, thereby minimizing biomass losses. Understanding role mitigating impact abiotic by regulating homeostasis holds great potential for advancing sustainable agricultural practices production. This review presents advances characterizing influence well preserving equilibrium attenuating biological damage associated with It underscores effects sustaining increasing yield via improved nutritional efficiency stress mitigation.

Endophytes, as microorganisms widely present in plants, have an important role plant growth and development. Abiotic stresses are very essential influence on Endophytes host plants diverse, however, beneficial endophytes used to make resistant abiotic stresses. This review focuses studying the regulatory roles of different under stresses, explained special pathway related mechanism heavy metal stress, such cadmium, manganese zinc stress. How do dominant respond salt heat stress affect physiological characteristics? In addition, we also summarized potential application reducing toxicity pathogens, promoting crop growth, biomedicine ecological restoration, other aspects, provide reference for further in-depth research action effective utilization endophytes.

Hemarthria compressa, a widely cultivated forage grass, is critical for supporting livestock production and maintaining the ecological balance in grassland ecosystems. Enhancing its stress resistance productivity crucial sustainable utilization development. Silicon (Si) Selenium (Se) are recognized as beneficial nutrients that promote plant growth tolerance, modulate of plant-microorganism interactions. However, intricate linkages between endophytes shifts host grass induced by Si/Se amendments poorly understood. In this study, pot experiment was conducted to examine effects foliar-applied on nutritional quality H. compressa well composition, diversity potential functions endophytic bacteria leaves. Both Si Se treatments significantly improved biomass approximately 17%. Nutritional also improved, with application increased neutral detergent fiber contents 25.6% 5.8%, while enhanced content from 0.055 mg kg−1 0.636 kg−1. Furthermore, altered structure leaf bacterial community, resulting an alpha more modularized co-occurrence network. Moreover, both enriched growth-promoting genera such Brevundimonas Truepera.

Glycyrrhiza uralensis Fisch (G. uralensis) is a key species for windbreak and sand fixation, possessing notable pharmacological economic value. However, the yield of G. considerably impacted due to its cultivation in arid, semi-arid, salt-affected regions. Silicon (Si) has been reported improve plant tolerance drought salt stress by regulating nitrogen secondary metabolism. Herein, effects Si treatment on metabolism seedlings under (D), (S), drought-salt (SD) stresses were investigated combination with physiological transcriptomic analyses. The results indicated that conditions significantly inhibited growth suppressing counteracted these inhibitions some extent. Specifically, increased soluble protein content approximately 15% D stress. Furthermore, elevated glycyrrhetinic acid about 89% SD increasing primary metabolites expression enzymes involved biosynthesis glycyrrhizic liquiritin, including 3-hydroxy-3-methylglutaryl CoA reductase (HMGR), squalene synthase (SQS), β-amyrin (β-AS). In summary, our findings suggest could alleviate adverse induced and/or metabolisms, which further triggered accumulation metabolites, ultimately improving resistance cultivated seedlings. This work provides direction resistance.
