of plant defense mechanisms by a combination of ISR plus biocontrol ability was
also validated by studies of several PGPR that produce VOCs (Shafi et al. 2017; Cao
et al. 2011). The occurrence of such dual potentiality can be exemplified by VOCs
like 2, 3-butanediol, isoprene and acetoin that are produced by different PGPR (Lee
et al. 2015; Ryu et al. 2004). Plant pathogens can also be controlled by many PGPR
via HCN production, a recognised VOC which disrupts the electron transport system
that leads to blocking the energy supply of the pathogens (Patel and
Minocheherhomji 2018).
