AB The ability of exopolysaccharides produced by medicinal mushroom Tremella mesenterica to influence the mechanisms of plant resistance to viruses has been studied. It was established that neutral polysaccharides (100−1000 μg/mL) can inhibit the formation of local lesions induced by the tobacco mosaic virus (TMV) (86%−96%) in Nicotiana tabacum and Datura stramonium plants. Acid water-soluble glucuronoxylomannan (GXM) in a concentration of 1000−2500 μg/mL activates the mechanisms of virus localization and also the acquired virus resistance (AVR) in plants supersensitive to TMV de novo. This is confirmed by the fact that actinomycin D (10−20 μg/mL), an inhibitor of DNA-dependent RNA-polymerase, partially inhibits the development of AVR. The possibility of using the natural product GXM as an instrument to study the mechanism of AVR as a method to decrease viral infection lesions in plants is under discussion.
