Enhancing maize defense through volatile organic compound research
This research explores the role of volatile organic compounds (VOCs) in maize defense against Dalbulus maidis and its parasitoid Anagrus virlae. It aims to restore VOC emissions in modern hybrids to improve resistance and attract natural enemies, particularly under high temperatures.
Overview
This innovative research project focuses on the role of volatile organic compounds (VOCs) in maize plants to enhance their defense mechanisms against herbivores, specifically Dalbulus maidis, and to attract the parasitoid Anagrus virlae. Modern maize hybrids have been found to emit significantly fewer VOCs compared to landraces, reducing their natural defense capabilities. By restoring these VOC emissions, this project seeks to improve maize resistance to pests and increase the attraction of natural enemies, especially under high-temperature conditions exacerbated by climate change.
Technical specifications
Key features:
- Evaluation of VOC emissions in different maize hybrids using the aeration technique.
- Comparison of VOC profiles between healthy and herbivore-exposed plants under both standard and elevated temperature conditions (37°C day/20°C night).
- Use of dual-choice olfactometers to test D. maidis attraction and Y-tube olfactometers to assess parasitoid response.
The study will assess how breeding has affected maize VOC emissions and their effectiveness in pest deterrence and parasitoid attraction. The project involves collaboration with experts from UBA-CONICET and Semion, Argentina, to enhance methodological approaches and analytical accuracy.
Technology readiness level
Currently at TRL 2, this research is in the early experimental phase, focusing on the fundamental understanding of VOC interactions in maize plants. The project is seeking partnership support for equipment and funding to advance the research towards higher TRL stages.
