“…A modified method of Mertz et al (1980) was followed here. Fifteen-day-old seedlings were transferred to glass bottles (7 Â 10 cm) containing 50 mL Hoagland's solution (Hoagland et al, 1950), pH 6.6 amended with known concentration of aflatoxin dissolved in 500 lL 0.5% aqueous acetone.…”

“…Uptake of aflatoxin by maize (Mertz et al, 1980(Mertz et al, , 1981, citrinin, patulin and terreic acid by rice seedlings (Rao et al, 1982), ochratoxin A by coffee plants (Mantle, 2000), and fumonisin by wheat plants (Zitomer et al, 2010) were the major studies where mycotoxin uptake was successfully proved. Moreover, earlier work conducted in our laboratory revealed the aflatoxins uptake ability of green leafy vegetables (Hariprasad et al, 2013).…”

“…Aflatoxin B1 (AFB1) can be translocated from the roots to the stems and leaves. If the soil microorganisms do not rapidly degrade the aflatoxin contained within the plowed under stover and grains, the possibility that the roots of the seedlings of the following year's crop will both absorb and translocate the aflatoxins to both the stems and leaves exists [10]. This could be hazardous to the plant's growth and development as well as to the consumer's health.…”

Mycotoxins: Producing Fungi and Mechanisms of Phytotoxicity

Abstract:Mycotoxins are secondary fungal metabolites, toxic to humans, animals and plants. Among the hundreds of known mycotoxins, aflatoxins, citrinin, patulin, penicillic acid, tenuazonic acid, ochratoxin A, cytochalasins, deoxynivalenol, fumonisins, fusarin C, fusaric acid, and zearalenone are considered the types that most contaminate cereal grain. The majority of the mycotoxins in these groups are produced by three fungal genera: Aspergillus, Penicillium and Fusarium. These metabolites primarily affect the seed quality, germination, viability, seedling vigour, growth of root and cleoptile. Additionally, since the fungi responsible for the production of these mycotoxins are often endophytes that infect and colonize living plant tissues, accumulation of mycotoxins in the plant tissues may at times be associated with development of plant disease symptoms. The presence of mycotoxins, even in the absence of disease symptoms, may still have subtle biological effects on the physiology of plants. Several studies highlight the toxic effects of mycotoxins on animals and cell lines but little is known about the mode of action of most of these metabolites on plant cells. The most important mycotoxins with phytotoxic effects and their producers in addition to their discovery are briefly outlined below and will be addressed in this article.

“…Aflatoxins are absorbed by plants and translocated to and distributed within specific cellular compartments (McLean, 1993;McLean et al, 1994). Studies on aflatoxin metabolism in plants indicate either a lack of metabolism (Mertz et al, 1980;Reiss, 1984) or the detection of metabolites (Howes et al, 1991;McLean, 1993).…”
