Reliable detection of potato pathogens via volatile organic compound (VOC) analysis remains challenging because VOC emissions depend strongly on microbial metabolism and host physiology. In this study, gas chromatography-mass spectrometry (GC–MS) data combined with a multivariate chemometric workflow were used to characterize VOC profiles of potato tubers infected with Rhizoctonia solani and Alternaria solani , and to compare...

Early detection of the Asian longhorned beetle ( Anoplophora glabripennis , ALB), a destructive wood-boring pest, remains challenging in living trees. Volatile organic compounds (VOCs) have gained increasing attention as potential detection cues due to their key roles in plant–insect interactions, yet trunk-based volatile responses to wood-boring herbivores are still poorly understood. Here, we present a detailed case study ch...

Volatile organic compounds (VOCs) can serve as sensitive indicators of plant health and pathogen infection. In this study, gas chromatography–mass spectrometry combined with multivariate chemometric analysis was applied to identify VOC patterns specific to potato wart disease caused by the pathogen Synchytrium endobioticum . Healthy and artificially infected potato tubers were analyzed under controlled conditions, and the resu...
