Single-Stranded DNA Plant Viruses: Molecular Mechanism of the Systemic Resistance of Plants to Viral Infection

This review details on the genomic structure, strategy and genetic mechanisms of the replication of singlestranded DNA plant viruses. It is considered in detail the protective mechanisms of plant resistance to phytoviruses. Literature data show the manifestation of resistance to viruses when virus entering into the plant, accumulation and dissemination of infectious viral material through the plant. Particular attention is given to specific protective responses in hypersensitive plants: necrosis infected cells and resistance to negative impact of virus infection.
