The impact of root exudates, volatile organic compounds, and common mycorrhizal networks on root system architecture in root-root interactions

Plants constantly communicate with coexisting neighbors and adjust their physiological morphological characteristics, including changes in root system architecture (RSA). Increased or decreased biomass accumulation, horizontal vertical asymmetric distribution are the main behavioral performances. Some evidence has shown that these performances associated plant plasticity such as secretion of exudates release volatile organic compounds (VOCs) describe role common mycorrhizal networks (CMNs) a communication pathway during belowground interplant interaction. Here, we highlight direct cues signals indirect effects via regulating soil nutrients microorganisms media root-root interactions on RSA have been taken into consideration. At last, existing knowledge gaps potential research directions outlined for better understanding RSA.
