“…10 The possible role of phenolic compounds as "soil toxins" was first suggested by Schreiner and Reed in 1908. 162 Since then, a number of phenolic and phenolic-related compounds have been isolated and acclaimed as allelochemicals 9 -n ' 36 tions with soil components, phenolics are absorbed and can be metabolized by allelochemicaltolerant plants. 171 Such processes may account for the reduced allelopathic effect of phenolics in most properly managed soils.…”

Numerous reports have been published on the occurrence, isolation, and characterization of phenolic compounds in plant-soil systems. The low molecular weight phenolics are of great interest because of their effects as allelopathic compounds and plant growth regulators, and they have traditionally been considered as defense molecules in plant-pathogen interactions. More recently, their role as signal molecules in plantmicrobe systems has become evident. Specific molecules can act either as inducers for virulent genes in plantpathogen systems, such as Agrobacterium, or as inducers and "repressors" in Rhizobium-legumc and probably other symbiosis. The overall regulation role of these compounds in compatible and incompatible host-microbe interactions is discussed in this review.

“…Various mycotoxins were investigated since early last century for individual toxicity, usually in regard to acute pathologies (Schreiner & Reed 1908). However, recent research is indicating complex interactions between chronic co-exposure to multiple mycotoxins possibly having synergistic, or even mitigating effects Grenier & Oswald 2011).…”

Mycotoxins, toxic secondary metabolites of fungi, affect global agriculture so prolifically that they are virtually ubiquitous at some concentration in the average human diet. Studies of in vitro and in vivo toxicity are discussed, leading to investigations of co-exposed mycotoxins, as well as carcinogenic effects. Some of the most common and toxicologically significant mycotoxins, such as the aflatoxins, ochratoxins, fumonisins, deoxynivalenol, T-2 toxin, HT-2 toxin, patulin, zearalenone, and some ergot alkaloids are outlined. The wide variety of pathogenic mechanisms these compounds employ are shown capable of inducing a complex set of interactions. Of particular note are potential synergisms between mycotoxins with regard to carcinogenic attributable risk, indicating an important field for future study.

“…9,14 Coumarin has been widely studied for allelopathic effects on root growth, organ considered the primary target of this compound. 16 Earlier investigations indicated clearly that coumarin changed root cell polarity of growth, causing an inhibition of longitudinal root cell elongation accompanied by a simultaneous stimulation of radial expansion. 6,17 These effects were also observed in alfalfa grass, where the thickness of seminal roots was enlarged abnormally because of an inhibition of the longitudinal root growth.…”
