Plant Targeted Metabolomics: Precision for Plant Research

Plant targeted metabolomics is a specialized approach for accurately quantifying predefined plant metabolites using advanced LC-MS/MS platforms. Unlike untargeted metabolomics, which provides a broad but semi-quantitative overview, this method ensures absolute concentrations, high reproducibility, and pathway-specific coverage.

With this service, you can:

  • Uncover stress-response mechanisms under drought, salinity, or pathogen attack.
  • Support crop breeding programs by linking metabolites to yield and quality.
  • Validate functional genomics findings through targeted metabolic profiles.
  • Measure low-abundance compounds such as phytohormones with femtomolar sensitivity.

By focusing on the metabolites that matter most, our targeted metabolomics solution turns complex data into clear, actionable insights for research and development.

Why Use Plant Targeted Metabolomics?

Your plant-focused projects often demand more than a broad metabolic snapshot—they require pinpoint accuracy, clear biological context, and data you can rely on for confident decision-making. Our targeted metabolomics service meets those needs in five key ways:

  • Pathway-Focused Confirmation

Measure only the metabolites that define your pathway of interest—phenylpropanoids, phytohormones, central-carbon intermediates, and more—so you can validate research hypotheses with precision.

  • Ultra-Low Detection for Critical Signals

Triple-quadrupole LC-MS/MS in MRM mode reaches femtomolar sensitivity, enabling reliable quantification of ABA, SA, JA, and other signalling molecules that drive stress responses and developmental cues.

  • Batch-to-Batch Reproducibility

Rigid QC checkpoints—pooled QC samples, isotope-labelled internal standards, and CV < 15 % across runs—ensure that the differences you observe between genotypes, treatments, or time points are truly biological.

  • Actionable Markers for Breeding and Trait Selection

Customisable panels covering sugars, organic acids, amino acids, phenolics, and secondary metabolites deliver quantitative markers you can feed directly into QTL mapping, genomic-selection models, or quality-control pipelines.

  • Transparent, Traceable Data Packages

Each report includes absolute concentrations, QC metrics, and instrument parameters, giving you complete traceability from sample to result—no hidden steps, no unanswered questions.

Integrated Analysis of Phytohormones Reveals Dynamic Responses to Salinity Stress in Arabidopsis thaliana Seedlings


Journal: Plant Physiology

Published: June 2018

DOI: https://doi.org/10.1104/pp.18.00293


Background

Understanding the molecular responses of plants to salinity stress is crucial for crop improvement. Phytohormones play a pivotal role in orchestrating these responses. This study aims to comprehensively analyze the dynamics of phytohormones in Arabidopsis thaliana seedlings under salinity stress.


Samples

Arabidopsis thaliana (Columbia-0 ecotype) seedlings were used for method validation and stress experiments. The study focused on shoots and roots harvested from plants subjected to either control conditions or 150 mM NaCl-induced salinity stress.


Technical Methods

Chemicals and Materials: Authentic standards and isotopically labeled counterparts were sourced from reputable suppliers. Chemicals, including formic acid, ACN, and MeOH, were procured from Merck.

Solubility Experiment: The solubility of selected BRs was investigated using different concentrations of aqueous ACN. UHPLC-ESI-MS/MS was employed for analysis, and relative yields were calculated.

Chlorophyll Extraction: Chlorophyll a and b were extracted using aqueous ACN at varying concentrations. Spectrophotometric measurements determined chlorophyll content.

Stability Experiment: Stability of analytes was examined under different conditions. Enzymatic activity in plant extracts was assessed using a proposed sample preparation protocol.

Sample Extraction and Purification: Plant material was extracted using ice-cold 50% aqueous ACN. Solid-phase extraction (SPE) with Oasis HLB RP cartridges facilitated purification.

UHPLC-ESI-MS/MS Conditions: Targeted compounds were analyzed using UHPLC coupled with a triple quadrupole mass spectrometer. Different elution conditions were applied for compounds detected in ESI(+) and ESI(-) modes.

Method Validation: Calibration curves, LOD, and LOQ were determined for UHPLC-ESI-MS/MS. Analyte losses during purification were evaluated, and method accuracy and precision were assessed.

Genevestigator Analysis: The Genevestigator tool was employed for meta-analytical assessment of gene expression under salt stress conditions, identifying salt stress as a significant modulator of hormone-related gene expression.


Results & Findings

Phytohormone Profiling: Comprehensive quantification of phytohormones provided insights into their dynamics under salt stress, highlighting key regulatory pathways.

Solubility Patterns: Solubility experiments revealed the behavior of selected BRs under different solvent conditions, aiding in the understanding of their chemical properties.

Chlorophyll Content: Chlorophyll extraction and spectrophotometric analysis provided information on the physiological impact of salt stress on Arabidopsis seedlings.

Stability of Analytes: Stability experiments elucidated the robustness of the proposed sample preparation protocol, ensuring reliable quantification of phytohormones.

Can you analyze different plant tissues in one project?

Yes. We can process leaves, roots, seeds, tubers, flowers, and fruits within the same project. For multiple tissue types, we recommend separate extraction workflows to minimize matrix effects.

What is the minimum number of biological replicates recommended?

At least 3 biological replicates per group are advised for robust statistical interpretation, including PCA, OPLS-DA, and pathway analysis.

Do you accept lyophilized or dried plant samples?

Yes, provided they are completely dried and properly sealed. Minimum required amount: ≥100 mg dry weight.

Can metabolite panels be customized?

Absolutely. We offer customized panels to target specific pathways (e.g., lignin biosynthesis, flavonoid metabolism) or species-specific metabolites.

Do you provide experimental design support?

Yes. Our technical team offers free consultation on sample size, target panel selection, and appropriate controls.

How do you correct for batch effects in large-scale projects?

We normalize using internal standards and pooled QC samples, combined with statistical correction algorithms, ensuring consistent data across multiple batches.

What is the detection limit and quantification range?

Most metabolites can be quantified from femtomolar to micromolar levels, validated using multi-point calibration curves with R² ≥ 0.99.

Are isotope-labeled standards used for every metabolite?

We include isotope-labeled internal standards for key metabolites. For compounds without labeled standards, we apply class-based normalization strategies for accurate quantitation.

How do you ensure accurate identification of structural isomers?

Optimized chromatographic separation and MRM transitions are applied. If isomers cannot be fully resolved, combined quantitation with annotations is provided.

Can you analyze rare or species-specific secondary metabolites?

Yes. We can configure custom MRM transitions and reference standards for compounds such as glucosinolates, indolic compounds, or unique alkaloids.

How is method reproducibility validated?

We perform intra- and inter-day precision tests, recovery studies, and matrix effect evaluations before large-scale analysis to ensure reliability.
