The role of arbuscular mycorrhizal symbiosis in plant abiotic stress

Frontiers in Microbiology, Год журнала: 2024, Номер 14

Опубликована: Янв. 18, 2024

Arbuscular mycorrhizal fungi (AMF) can penetrate plant root cortical cells, establish a symbiosis with most land species, and form branched structures (known as arbuscules) for nutrient exchange. Plants have evolved complete plant–AMF system to sustain their growth development under various types of abiotic stress. Here, we highlight recent studies AM the regulation process. The roles host interactions in enhancing drought resistance, increasing mineral uptake, regulating hormone synthesis, improving salt alleviating heavy metal stress were also discussed. Overall, variety stresses will aid applications AMF sustainable agriculture improve production environmental safety.

Plants, the cornerstone of life on Earth, are constantly struggling with a number challenges arising from both biotic and abiotic stressors. To overcome these adverse factors, plants have evolved complex defense mechanisms involving cell signaling pathways network interactions microorganisms. Among interactions, relationship between symbiotic arbuscular mycorrhizal fungi (AMF) strigolactones (SLs) stands as an important interplay that has significant impact increased resistance to environmental stresses improved nutrient uptake subsequent enhanced plant growth. AMF establishes mutualistic partnerships by colonizing root systems, offers range benefits, such absorption, water stresses. SLs play fundamental role in shaping architecture, promoting growth lateral roots regulating responses. can promote production release plants, which turn due their molecules ability attract beneficial microbes. The complete knowledge this synergy potential develop applications optimize agricultural practices, improve use efficiency ultimately increase crop yields. This review explores roles played development stress tolerance, highlighting individual contributions synergistic nature interaction.

The Utilization and Roles of Nitrogen in Plants

Forests, Год журнала: 2024, Номер 15(7), С. 1191 - 1191

Опубликована: Июль 10, 2024

Nitrogen (N) is an essential mineral element for plants and the main component of protein, nucleic acid, phospholipid, chlorophyll, hormones, vitamins alkaloids. It involved in all stages plant growth development. Low-N stress seriously hinders reduces yield quality. Plants have evolved a series elaborate regulatory mechanisms N uptake assimilation to cope with different soil states. After absorbed utilized by plants, it plays important roles phytohormones, microRNA (miRNA), root development mycorrhizal symbiosis environmental stress. Here, we highlight research progress on regulation absorption assimilation. Then, emphasize regarding hormone signals, miRNA, lateral growth, drought resistance, anthocyanin synthesis symbiosis. A thorough understanding uptake, utilization interaction other biological processes helpful improve use efficiency breed “less-input-more-output”.

Species-specific functional trait responses of canopy-forming and rosette-forming macrophytes to nitrogen loading: Implications for water–sediment interactions

Environment International, Год журнала: 2024, Номер 185, С. 108557 - 108557

Опубликована: Март 1, 2024

Globally intensified lake eutrophication, attributed to excessive anthropogenic nitrogen loading, emerges as a significant driver of submerged vegetation degradation. Consequently, the impact on decline macrophytes has received increasing attention. However, functional trait-based approach exploring response loading and its environmental feedback mechanism was unclear. Our study utilized two different growth forms (canopy-forming Myriophyllum spicatum, rosette-forming Vallisneria natans) established "submerged macrophytes-water–sediment" microcosms. We assessed influence across four targeted total concentrations (original control, 2, 5, 10 mg/L), plant traits, water parameters, sediment properties, enzyme activities, microbial characteristics. findings revealed that high (10 mg/L) adversely impacted relative rate fresh biomass chlorophyll content in canopy-forming M. while a/b free amino acid increased. On contrary, photosynthetic traits resource-conservative V. natans were not affected by loading. Functional (growth, photosynthetic, stoichiometric) spicatum but exhibited correlations with variables. Nitrogen significantly increased concentration components overlying pore water. The presence reduced ammonia both water, decreased organic carbon inhibited extracellular planting mitigated their negative effects. Furthermore, rhizosphere bacterial interactions less compact compared bare eukaryotic communities complexity connectivity. Path modeling indicated direct effects amplified indirect also attenuating enzymes. restoration can mitigate eutrophication resulting from through species-specific changes or mechanisms water–sediment system.

The Root-Colonizing Endophyte Piriformospora indica Supports Nitrogen-Starved Arabidopsis thaliana Seedlings with Nitrogen Metabolites

International Journal of Molecular Sciences, Год журнала: 2023, Номер 24(20), С. 15372 - 15372

The root-colonizing endophytic fungus Piriformospora indica promotes the root and shoot growth of its host plants. We show that promotion Arabidopsis thaliana leaves is abolished when seedlings are grown on media with nitrogen (N) limitation. neither stimulated total N content nor did it promote 15NO3- uptake from agar plates to under N-sufficient or N-limiting conditions. However, roots were co-cultivated 15N-labelled P. indica, more labels detected in N-starved plants but not supplied sufficient N. Amino acid primary metabolite profiles, as well expression analyses transporter genes suggest alleviates adaptation limitation condition. alters genes, which participate relocation NO3-, NH4+ metabolites propose participates plant's metabolomic against by delivering reduced host, thus alleviating metabolic starvation responses reprogramming metabolism-related genes.
