Study TitleDetection of Methyl jasmonate (MeJA) in Plant root VOCs
Study SummaryMethyl jasmonate (MeJA) is a well-known plant hormone known for plant defense and plant-plant signaling. However, most of the studies are focussed on its aboveground presence and functions. Here we report that MeJA is also released by plant roots in a volatile form. More importantly, it is shown in Arabidopsis growing in natural conditions in soil.

Project Title:Arabdiopsis Root VOCs
Project Summary:The rhizosphere is a unique niche surrounding plant roots, where soluble and volatile molecules mediate signaling between plants and the associated microbiota. The preferred lifestyle of soil microbes is in the form of biofilms. However, little is known about whether root VOCs (rVOCs) can influence soil biofilms beyond the 2-10 mm rhizosphere zone influenced by soluble root exudates. Here, we report that rVOCs shift the microbiome composition and growth dynamics of complex soil biofilms. This signaling is evolutionarily conserved from ferns to higher plants, which suggests its coevolution. The defense phytohormone methyl jasmonate (MeJA) is present in rVOCs and drives this bioactivity at nanomolar levels within a few hours.
