Abstract Studying natural variation in multi-stress resistance is central for predicting and managing the population dynamics of wild plant species under rapid global change. Yet, it remains a challenging goal this field to integrate knowledge on complex biochemical underpinnings targeted ‘non-model’ species. Here, we studied latitudinal divergence combined drought heat stress European populations dune Cakile maritima , by combining comprehensive phenotyping with metabolic profiling via FT-ICR-MS UPLC-TQ-MS/MS. We observed pronounced constitutive growth phenology, leaf functional traits defence chemistry (glucosinolates, alkaloids) among origins. Most importantly, magnitude reduction was partly weaker southern plants associated plastic responses (root expansion, abscission) stress-induced modulation primary specialized metabolites known functions not only abiotic but also biotic resistance. Our study supports that divergent selection has shaped expression numerous morphological mediate higher populations, highlights metabolomics powerful tool explore mechanistic local adaptation Highlight Plant its exhibits clines across coastal plant.

Abstract Dark septate endophytes (DSE) are widespread colonizers of plant roots and have important ecological functions such as the regulation growth nutrient uptake. The mechanisms by which DSE mycelium its extracellular metabolites promote not yet been determined. Here, growth‐promoting effects (H) (M) on alfalfa ( Medicago sativa L.) were investigated. Treatments H, M HM increased total biomass 23.9%, 47.2% 47.1%, respectively. H modified root structure increasing volume reducing tissue density, promoting Metabolomic analysis indicates that exudates contained 204 different types, mainly lipids lipid‐like molecules, organic acids derivatives, benzenoids. There more organoheterocyclic compounds fewer derivatives in treatment than M. Pathway shows had greater glycerophospholipid metabolism N‐glycan biosynthesis pathway. results provide information involved metabolic promotion DSE.

Climate change is a notable challenge for agriculture as it affects crop productivity and yield. Increases in droughts, salinity, soil degradation are some of the major consequences climate change. The use microorganisms has emerged an alternative to mitigate effects Among these microorganisms, dark septate endophytes (DSEs) have garnered increasing attention recent years. Dark shown capacity mitigating reducing harmful agriculture, such drought, reduced nutrient availability soil. Various studies show that their association with plants helps reduce abiotic stresses increases availability, enabling thrive under adverse conditions. In this study, effect DSEs underlying mechanisms help develop higher tolerance were reviewed.

This study investigates how extracellular polymeric substances (EPS) synthesized by dark septate endophytic (DSE) improve alfalfa's drought resistance. Drought stress was simulated in hydroponic culture, and roots were treated with different EPS concentrations to determine their effects on tolerance applicable concentrations. Hydroponic solutions 0.25 0.50% alleviated leaf wilting increased total plant fresh weight 35.8 57.7%, respectively. SEM shows that attached the may have served protect root system. treatment significantly depressed MDA contents of roots, stems, leaves. Roots responded increasing soluble sugar antioxidant enzyme activities, while mitigating stem synthesizing lipid compounds, amino acids, organic acid metabolites. Five metabolites been reported be associated growth, namely 3-

Abstract. Akhir J, Herliyana EN, Surono, Budi SW. 2024. The first report of dark septate endophytes from Indonesian Pinus merkusii and its symbiosis role as a plant growth promoter in nursery condition. Biodiversitas 25: 312-321. To encourage the healthy Jungh et de Vriese seedlings at seedling stage, Dark Septate Endophytic (DSE) fungi were used promoters. In this study, four DSE strains, i.e., Apls 1.5.3, Pls 32.1, Hs14.6a, Hs14.6c isolated P. roots, tested for their ability to stimulate seedlings. After 14 weeks incubation conditions, inoculated with strains experienced higher increase height stem diameter when compared control treatment. Overall, biomass results treated performed better than those control. Root colonization showed that 4 significantly outperformed strain other controls regarding nutrient (nitrogen) uptake. findings study are show 1.5.3 is similar Cylindroccarpon, Hs14.6a Cladophialophora sp., 32.1 Oncopodiella trigonella based on identification phylogenetic trees can be seeds merkusii, pine species native Indonesia.

Dark septate endophytes (DSE) may facilitate plant growth and stress tolerance in stressful ecosystems. However, little is known about the response of medicinal plants to DSE, especially under heavy metal stress. This study aimed investigate how DSE affects Dendranthema morifolium cadmium (Cd) In this investigation, sterile non-sterile inoculations were carried out evaluate effect three strains on D. stressed with Cd. For root, DSE15 or inoculation resulted enhanced root biomass, volume, Cd content roots, indoleacetic acid (IAA) levels DSE7 significantly roots at 1 5 mg Cd/kg soil. Regarding impact stems leaves, conditions, effectively regulated shoot height, chlorophyll level, superoxide dismutase (SOD) content. Under positively influenced biomass while had no significant them when subjected effects flowers increased flower stress, reduced transfer coefficient Importantly, soil, promoted 1, 5-dicaffeoylquinic by 18.29% 21.70%. The interaction between soil factors revealed that species organic carbon available nitrogen content, These results contribute a better understanding DSE-plant interactions habitats contaminated metals demonstrate potential utility for cultivating plants.
