SISE, free LabView-based software for ion flux measurements

Area of Science:

• Plant Physiology
• Biophysics
• Analytical Chemistry

Background:

• Plant growth relies on mineral nutrient uptake and transport.
• Electrophysiological techniques are crucial for studying ion transport and signaling in plants.
• Scanning Ion-Selective Electrodes (SISE) offer a non-invasive method for measuring ion fluxes.

Purpose of the Study:

• To develop user-friendly software for Scanning Ion-Selective Electrodes (SISE) measurements.
• To facilitate the recording and analysis of ion flux data in plants.
• To provide freely accessible tools for researchers studying plant ion transport.

Main Methods:

• Development of two LabView-based software programs: SISE-Monitor for data acquisition and SISE-Analyser for data analysis.
• Implementation of automated electrode movement and data processing routines.
• Provision of executable files for routine use and source code for customization.

Main Results:

• Successful creation of SISE-Monitor and SISE-Analyser software.
• Enabled efficient and accurate recording and analysis of plant ion fluxes.
• Made software freely available with source code for further development.

Conclusions:

• The developed LabView software enhances the application of SISE for studying plant ion transport.
• Freely available software lowers barriers for researchers investigating mineral uptake and plant development.
• The open-source nature allows for integration with other measurement techniques, such as fluorescent dye imaging.
