Plant Hormone Analysis

Plant Hormone Analysis Inquiry

Plant hormones are highly dynamic chemical messengers that play essential roles in the regulation of plant physiological processes, including cell growth, organ differentiation, and response to biotic and abiotic stresses. Therefore, analysis and monitoring of plant hormones forms a valuable tool in plant performance improvement and new crop trait development.

As the plant hormones often present at fairly low concentrations, and their amounts and distributions and are actively changing, it is critical to analyze the hormone levels in real time with high sensitivity. Lifeasible, as a leading plant biotechnology with a long history of plant physiological studies, provides both biosensor-based and mass spectrometry-based approaches that ensure continuous and accurate detections of plant hormones. 

Biosensor-based methods allow continuous monitoring of hormone levels, as well as visualization of local distributions of targeted hormones. Lifeasible provides a list of biosensors that can be applied to the detection of a wide range of hormones in various types of plant tissues.

  • Electrochemical biosensors. Utilizing current or impedance changes resulted from enzymatic redox reactions as sensory readout; intermediate compounds that are specific to certain plant hormones can also be used as biosensors or electrodes to monitor hormone levels in real-time (Figure 1).  
  • Immunosensors. Single stranded RNAs or DNAs, also known as aptamers, fold to create binding sites for ligand molecules. Specially engineered aptamers can bind to targeted plant hormones.
  • Genetically encoded biosensors. Genetic reporters of plant hormones are designed based on the promoter regions of the targeted plant hormones.

Mass spectrometry-based methods are highly sensitive approaches that allow accurate identification and quantification of plant hormones.

  • Gas chromatography-mass spectrometry (GC-MS). Gas chromatography (GC) is an efficient method for the detection and sorting of volatile organic compounds (VOC). When combined with mass spectrometry (MS), compositions of hormones can be separated and analyzed in a linear format (GC-MS), with high fidelity.
  • Liquid chromatography-mass spectrometry (LC-MS). Similar to GC-MS, the LC-MS technology combines high-throughput compound separation with ultra-sensitive detection methods, allowing the analysis of plant hormone molecules within a complicated biological matrix.  

Sample requirements:

  • Cell sample. After sampling, centrifuge, remove the medium, put it in liquid nitrogen immediately, and store it at -80°C. The sample quality is recommended to be >1g, and 3 biological replicates should be prepared.
  • Leaf, stem, flower samples. Put it in liquid nitrogen immediately after removal, and then store it at -80°C. The sample quality is recommended to be >1g, and 3 biological replicates need to be prepared.
