Trade‐offs between root‐secreted acid phosphatase and root morphology traits, and their contribution to phosphorus acquisition in Brassica napus

Abstract Oilseed rape ( Brassica napus ) is one of the most important oil crops in world and shows sensitivity to low phosphorus (P) availability. In many soils, organic P (Po) main component soil pool. Po must be mineralised Pi through phosphatases, then taken up by plants. However, relationship between root‐secreted acid phosphatases (APase) root morphology traits, two P‐acquisition strategies response deficiency, unclear among B. genotypes. This study aimed understand their how they affect acquisition, which crucial for sustainable utilisation agricultural resources. showed significant genotypic variations APase activity per unit fresh weight (SAP) total plant (total SAP) 350 Seed yield was positively correlated with SAP but not significantly SAP. Six traits 18 genotypes contrasting biomass were compared under normal Pi, Po. Genotypes longer length (TRL) reduced SAP, those shorter TRL increased deficiency. Additionally, three treatments, also treatment. conclusion, trade‐offs existed P‐deficient conditions. Total an trait These results might help breed greater ability availability

Investigations into soil organic phosphorus (Po) dynamics are instrumental in understanding the transformations and processes responsible for ecosystem productivity. However, quantitative analysis of Po a environment is extremely challenging due to low target analyte concentrations matrix interferences with chromatography analysis. Consequently, two-dimensional ion chromatography-tandem mass spectrometric (2D-IC-MS/MS) method was developed estimate concentrations. The first dimension diverted early eluting anions waste while preconcentrating P compounds trap column, followed by chromatographic separation detection second dimension. Detection done using spectrometer, quantification performed multiple reaction monitoring scan (MRM) method. linear range studied compounds, mostly nucleotides, 0.05-50 ng/mL. Most were detected quantified calcareous subsoil samples concentration ranges 0.70-51.78 ng/g. achieved that allowed unambiguous identification isobars/isomers isotopologues contributing MS detection. improvements extraction post-clean-up procedures required complexity extract composition, extreme effect and/or loss during preconcentration. ideal simultaneously analyzing from environmental elucidate key components dynamics.

Barley Growth and Phosphorus Uptake in Response to Inoculation with Arbuscular Mycorrhizal Fungi and Phosphorus Solubilizing Bacteria

Communications in Soil Science and Plant Analysis, Journal Year: 2023, Volume and Issue: 55(6), P. 846 - 861

Published: Nov. 29, 2023

Biostimulants and bioinoculants offer the potential to enhance nutrient use efficiency within agricultural cropping systems thus reduce amount of mineral fertilizers needed support crop growth. Considerable uncertainty, however, exists about their efficacy under different management regimes. The present field-based study investigated effects phosphorus (P) solubilizing bacteria (PSB) mycorrhizal (AMF) inoculants in presence a range mineral-based P fertilizers, including triple superphosphate (TSP), struvite rock phosphate (RP), on growth, yield, uptake barley (Hordeum vulgare L.). Two consecutive field experiments performed low soil (Eutric Cambisol) revealed that (PSB AMF) promoted plant grain yield. Moreover, comparison lacking bio-inoculants, application external sources combined with bio-inoculants led significant increases leaf concentration, total uptake, dry matter, Grain yield significantly correlated by roots above-ground parts (i.e. stems, leaves, spikes) as well concentration both seasons. It is concluded can help improve sustainable ultimately leading greater sustainability resilience cycling.
