Volatile organic compounds in pea plants: a comprehensive review

Area of Science:

• Agricultural Science
• Plant Biology
• Biochemistry

Background:

• Legumes, particularly peas (Pisum sativum L.), are vital for global food security and nutrition.
• Pea crops face significant losses from biotic and abiotic stresses, necessitating enhanced defense strategies.
• Plants utilize volatile organic compounds (VOCs) for communication and defense against environmental challenges.

Purpose of the Study:

• To review the emission patterns and biological functions of VOCs in peas.
• To explore the role of VOCs in pea responses to various stimuli like insects, pathogens, drought, and heat.
• To discuss mass spectrometry techniques applicable to pea VOC research.

Main Methods:

• Literature review focusing on pea VOC emissions and functions.
• Analysis of existing research on plant VOCs in response to stress.
• Discussion of mass spectrometry techniques for VOC identification and quantification.

Main Results:

• Peas emit specific VOCs in response to external stimuli, indicating a role in defense mechanisms.
• Limited research exists on pea VOCs, highlighting a gap in understanding their constitutive and induced emissions.
• VOCs show potential in plant-plant signaling and interaction with other organisms.

Conclusions:

• Pea VOCs play a role in the plant's defense system.
• Further functional studies are essential to fully understand and utilize pea VOCs.
• Harnessing pea VOCs offers potential for sustainable agricultural applications, including pest repellency and pathogen inhibition.
