Garden Guides | List of Viral Diseases of Plants

Sep 21, 2017· Plants, like humans, can become sick from viruses. A virus is a small, parasitic particle that causes infection. Most viruses are host specific, meaning a plant cannot transmit a virus to humans or another kind of plant, according to scientists at Rothamsted Research. Symptoms include yellowing or distorted leaves ...

Plant pathogens transmitted by pollen | SpringerLink

Pollen is a valuable source of germplasm for breeding and has few associated pests compared with other sources of genetic material. This review seeks to assist the development of appropriate phytosanitary measures by considering the pests that are transmitted by pollen. There are no invertebrates, bacteria, phytoplasmas or spiroplasmas that are pollen-transmitted.

Potato virus Y - Wikipedia

Potato virus Y (PVY) is a plant pathogenic virus of the family Potyviridae, and one of the most important plant viruses affecting potato production. PVY infection of potato plants results in a variety of symptoms depending on the viral strain.The mildest of these symptoms is production loss, but the most detrimental is 'potato tuber necrotic ringspot disease' (PTNRD).

Plant virus — Wikipedia Republished // WIKI 2

Viruses are extremely small and can only be observed under an electron microscope.The structure of a virus is given by its coat of proteins, which surround the viral genome.Assembly of viral particles takes place spontaneously.. Over 50% of known plant viruses are rod-shaped (flexuous or rigid). The length of the particle is normally dependent on the genome but it is usually between 300–500 ...

Insects are especially important vectors for plant viruses, and multiple viruses are often transmitted by the same insect species (Gray et al ., 2014; Gray and Banerjee, 1999). For phloem‐limited bacteria, the insect–vector relationship and pathogen niche is a polyphyletic trait, indicating that it has evolved independently multiple times ...

Plant Viruses - Viral Transmission and Disease

Horizontal Transmission In this type of transmission, the plant virus is transmitted as a result of an external source. In order to "invade" the plant, the virus must penetrate the plant's outer protective layer. Plants that have been damaged by weather, pruning, or plant vectors (bacteria, fungi, nematodes, and insects) are typically more susceptible to a virus.
