Abstract Examples of positive effects biodiversity on ecosystem functions have kept accumulating in the last two decades, and functional traits are considered suitable tools to explain their underlying mechanisms. However, rarely studied at scale where these mechanisms (e.g., complementarity) likely originate, that is, between interacting individuals. In a greenhouse experiment, we investigated how species diversity (i.e., monospecific or heterospecific tree pairs) affects within-individual leaf expression variation this effect is modified by soil conditions. While resource addition through phosphorus fertilization partly strengthened effects, inoculation microbiota (potentially leading increased accessibility) resulted counter effects. Hence, contrast our expectations, did not find synergistic treatments, but found distinct following an acquisitive conservative growth strategy. Overall, study showed trees’ adaptability resource-use strategy needs be alongside biotic abiotic aspects. The influence conditions essential understand behind complementarity individual level, which ultimately translate community scale.

Abstract Plant nutrient composition is a reliable tool to identify plant ecological strategies and niche differentiation. Here, we aimed (i) reveal the potential physiological mechanisms governing distinct foliar compositions among coexisting grassland species (ii) clarify role of taxonomy environmental conditions in these compositions. At local (grassland) scale, measured root morphological traits, photosynthetic parameters concentrations six macronutrients (N, P, S, K, Ca Mg) four micronutrients (Fe, Mn, Zn Cu) across 18 species. regional macro‐ micronutrient 76 site‐species combinations grasses forbs temperate meadow, typical, desert saline grasslands were Inner Mongolia. national collected data on macronutrient 513 Xinjiang, Qinghai‐Tibet Mongolia China. Compared with forbs, had 3.9 times higher branching intensity, but 58% 48% lower carboxylate exudation leaf transpiration rate. These acquisition transport led Ca, Mg Mn) than at scale. Most did not differ between whereas regardless type both scales. All exhibited stronger phylogenetic conservatism less control micronutrients. The biogeochemical segregation (Euclidean distance based PCA score concentrations) sympatric was meadow grasslands. Our results suggest that diverse can underlie forbs. linkage differentiation will advance our understanding coexistence adaptive strategy.

Abstract Background and aims Certain plant species release root carboxylates in response to phosphorus (P) limitation; however, the prevalence of exudate P-limited forest ecosystems remains unexplored due challenges field assessment. Methods Manganese (Mn) accumulation mature leaves can indicate presence carboxylate exudates rhizosphere soil. To account for environmental factors such as soil pH, a negative reference that does not is used comparison. In this study, we assessed multiple stands across types different levels P availability northern (Gansu) southern (Guangxi) China. Leaf samples were collected from 188 families representing various life forms, leaf Mn concentration ([Mn]) was analyzed proxy exudation patterns, using Dryopteridaceae reference. Results The results supported our hypotheses [Mn] higher forests China compared P-richer China, even though Additionally, observed with high Guangxi (82%) than Gansu (42%). Conclusion Our findings suggest potential common strategy among plants forests, where are released limitation, possibly ineffective mycorrhizal symbiosis nutrient acquisition. diverse systems exhibit varying availability, leading evolution distinct P-acquisition strategies.

Numerous phosphorus (P)-acquisition and -utilisation strategies have evolved in plants growing severely P-impoverished environments. Although these been well characterised for certain taxa, like Proteaceae, P-poor habitats are by a high biodiversity, we know little about how species other families cope with P scarcity. We compared the P-acquisition leaf P-allocation of Fabaceae Myrtaceae those Proteaceae same habitat. exhibited multiple strategies: P-mining carboxylates or phosphatases, uptake facilitated carboxylate-releasing neighbours, dependence on elevated soil availability after fire. Surprisingly, not all showed photosynthetic P-use efficiency (PPUE). Highly P-efficient positive correlations between PPUE proportion metabolite (enzyme substrates), negative phospholipids (cellular membranes) nucleic acid (mostly ribosomal RNA), while found no less species. Overall, that used wider range than to scarcity, at both rhizosphere level. This knowledge is pivotal better understand mechanisms underlying plant survival nutrient-impoverished biodiverse ecosystems.

Nonmycorrhizal cluster root-forming species enhance the phosphorus (P) acquisition of mycorrhizal neighbours in P-impoverished megadiverse systems. However, whether plants facilitate defence nonmycorrhizal against soil-borne pathogens, return and via their symbiosis, remains unknown. We characterised growth defence-related compounds Banksia menziesii (nonmycorrhizal) Eucalyptus todtiana (ectomycorrhizal, ECM) seedlings grown either monoculture or mixture a multifactorial glasshouse experiment involving ECM fungi native oomycete pathogens. Roots B. had higher levels phytohormones (salicylic jasmonic acids, jasmonoyl-isoleucine 12-oxo-phytodienoic acid) than E. which further activated salicylic acid-mediated response roots menziesii, but only presence fungi. also found that induced shift strategy todtiana, from secondary metabolites (phenolic flavonoid) towards phytohormone pathways. conclude play vital role interactions between severely environment, by introducing competitive component within facilitation interaction two plant with contrasting nutrient-acquisition strategies. This study sheds light on interplay beneficial detrimental soil microbes shape plant-plant nutrient-impoverished ecosystems.

Dry cultivation of rice (DCR) is one the important practices aimed at addressing freshwater resource shortages. However, non-renewable nature phosphate resources constrains agricultural development. In context contradiction between rice, water, and phosphorus, there little research on using silicon phosphorus relationship to improve availability uptake DCR. This experiment used field soil established five fertilization treatments: no application, low normal (0, 25, 75 kg·ha -1 P 2 O 5 ) (0P, 25P, 75P), along with two levels 45kg·ha SiO ), resulting in treatments 0P, 0PSi, 25PSi, 75P. The components plant were analyzed. results showed that adding 25P increased Olsen-P content (14.37%) by increasing Ca 8 -P (9.04%) Al-P (19.31%). Additionally, root leaf 7.6% 5.8%, respectively, comparable observed 75P treatment. On hand, increases malate (40.48%) succinate (49.73%) content, enhances acid phosphatase activity, abundance Bradyrhizobium , Paenibacillus Bacillus as well proportion Fusarium forming an “organic microbial” activated system. other addition alleviated limitations reducing ATP consumption roots through a decrease ATPase P-ATPase content. also minimized excessive NSC transport roots, thereby promoting shoot growth downregulating SUT1 SWEET11 SUS2 CIN2 . optimizing root-to-shoot ratio providing sufficient energy, volume upregulates OsPT2 OsPT4 OsPT8 uptake. summary, 25PSi optimizes promotes conversion organic acid, microbial, energy pathways.
