Genetic diversity of turnip mosaic virus and the mechanism of its transmission by Brassica seeds

Six isolates of turnip mosaic virus (I2, I3a, I3b, I7, I8, and I10) characteristic of viruses isolated from 87 samples of cultivated plants of the genus Brassica that had the symptoms of turnip mosaic in Moscow region were classified by the signs of lesion of host plants, response of indicator plant...

Description
Summary:Six isolates of turnip mosaic virus (I2, I3a, I3b, I7, I8, and I10) characteristic of viruses isolated from 87 samples of cultivated plants of the genus Brassica that had the symptoms of turnip mosaic in Moscow region were classified by the signs of lesion of host plants, response of indicator plants, and results of ELISA. According to preliminary information, one group of virus isolates was brought to Russia with the seed collection of Brassica rapa L. varieties. It was demonstrated that the TuMV I2 isolate is transmitted by seeds of TuMV sus ceptible and TuMV tolerant plants of the genus Bras sica at a frequency of up to 40%, and the mechanism of the virus transmission through infection of the embryo was shown.
