Microbial volatile organic compounds in plant defense: mechanisms, signaling networks, and agricultural applications

Airborne Immunity: A Bacterial Volatile Primes Plant Defenses by Unlocking a Phytoalexin Biosynthetic Checkpoint.

Microbial volatile organic compounds (mVOCs) enable plants to perceive microbial activity prior to physical contact, yet the contribution of individual bacterial volatiles to immune signalling and disease resistance remains incompletely understood. Here, headspace GC-MS analysis demonstrates that the hemibiotrophic pat...

This review analyses the growing field of microbial metabolites in agriculture, moving beyond the widespread narratives to evaluate the scientific foundations, efficacy claims, and ecological implications of their widespread application. This article discusses the widespread benefits of using microbial metabolites in...

Polyamine-mediated crosstalk in plant–microbe systems: implications for stress tolerance and crop protection

The interaction between plants and microbes is a complex network of signaling pathways that plays a pivotal role in plant health and resilience to environmental stressors. Recently, polyamines (PAs), including putrescine, spermidine, and spermine, have emerged as crucial mediators in the crosstalk between plants and mi...
