Biological indicator tabacum mosaic: virus (TVM) from plant communities in different regions at Ukraine

5. A. Stepanjuk, O. M. Garifulin

The virus infected plants of Solanaceae in different regions of Ukraine (seven totally) was screened for ecological monitoring purpose. It was released that these plants usually infected at complex manner with viruses of different groups, especially TVM was constant participant of infection process [I, 2]. The 16 TVM-strains (the nine tobacco's — from- Narodichi, Zhitomir re¬gion; the seven tomato's—from Pushc/la-Voditsa, Kiev region) have been studied by application RT-PCR technics. These research have not estimated virus population's distinctions on the base of changes of virus genome's functional site (coding fragment with the information about capcid protein). The all 16 strains can be classificated as TVM NT9 and TVM LE7 tobacco mosaic virus strains, that have been isolated and characterized previously at the same regions [1, 2]. In accordance to these facts it can be conclused about possibility of using TVM as biological indicator model of changes which take part at the nature. In addition, these properties may be used as basic dates.
