Abstract
The discovery of strigolactones has resulted in a confluence of various research topics like parasitic plants, arbuscular mycorrhizal fungi and phytohormones, which all play a big role in current global agricultural production. Over the past few decades, strigolactone research swiftly gained a spotlight, as to reveal their possible functions within plants and also the surrounding organisms in the rhizosphere. In this review, we explore the discovered functions of strigolactones with the main focus on the chemical structure of strigolactones and how it relates to the various biological responses they cause. We highlight their involvement in plant responses to abiotic stressors, like lack of available nutrients, high salinity, drought, extreme temperatures and presence of potentially toxic elements of environmental importance, while reflecting upon the strigolactone-mediated plant associations with arbuscular mycorrhizal fungi and nodule-forming, N-fixing bacteria. Furthermore, we elaborate on the current state of applied strigolactone research in agriculture and the probable bright future these compounds have in commercial use and what hurdles need to be overcome before they can be fully utilized.
