The coronavirus (scientific name: Tomato yellow leaf curl virus; in acronym: TYV) is a single-digit DNA virus that causes the disease of the Aboriginal Amir and severe damage to the tomato plants and other plants. The sex of the hepatitis Amir virus is one of a large variety of the kind of begomovirus that causes the disease.
The virus was first described in Israel in 1964. It is found that it harms the normal plant’s clothing and thus affects crop production. The virus is transmitted by the adult Bemisia tabaci, which is extracted from the plant’s tuberculosis. The virus is transmitted back to the plant’s tuberculosis. There is also the transmission of the virus between the wings during the mating.

The virus was first diagnosed in the 1960s in Israel, and it later expanded to tropical and Slavographic regions throughout the world.

The genome.
The genome of the virus consists of one single-divine DNA sheet that is raised about 2,800 narcotics. This genome is encoded by six overlapping reading frameworks (ORFs):
V1 - encodes the protein of the virus
V2 - Visitors to Symptoms and the virus movement in the plant
C1 - encodes the protein that is essential to replicating the virus
C2 - encodes the protein that acts
C3 - encodes the protein that increases the virus's reaction
C4 - encodes for protein that affects the virus movement in the plant, severity of symptoms and steroid range

The protein shelling the virus
The virus genome is wrapped in an icon-like particle called geminate. This particle consists of 110 sub-divine units of 30kDa promoted by the V1 gene. The protein of the virus shell protects the genome, leads the virus into the plantary and outside cell, pumps in the hesist movement in the plant and is essential for transmitting the virus in the body as the tobacco hay.

The route from the plant to the tobacco plant.
The virus arrives at the plant’s tuberculosis when feeding, it passes through the food canal located in stylet, to reach it to the esophagus and to which it penetrates the synthesized cell which constitutes a central crossroads in the digestive system of the tobacco pelvic that connects between the middle and the fireplace. Most of the viruses are absorbed in the seitanic cell and move to the circumcision, the blood system of the tobacco pelvic, while some viruses move forward to the rising intestine and the heatht intestines, where they are absorbed from the euthanol cells of the intestine into the blood system. The virus particles move in the lymphatics that have been planned until the arrival of the saliva glands where they are aligned with the main rock glands and moving forward into the rock pipe and from there they are injected together with rock back to the plant’s plant. The constant circular transmission of the virus is coordinated by its shell protein.

A range of inn
The range of the virus in agricultural crops in Israel includes the cultural tomato (Lycopersicon esculentum), excellent beans (Phaseolus Vulgaris), pepper (Capsicum annuum) and Chinese pepper (Capsicum chinense), lipidos (Eustoma salifalora), pongia, pongia, and flora. Also, most wild tomato species show symptoms. The disease is common in the Middle East and is also reported in the Far East, Africa, Europe, Caribbean and Central America. TYLCV was also reported in Japan, Mexico, Florida and Georgia.

Damage
The disease causes a halt to normal growth, yellow, small, and twisted leaves. In infecting a young plant stops plant growth and therefore does not develop flowering and fruit and crop level decrease. The disease is the main cause of cultural tomato growth, when the disease first erupted in Israel, a loss of 100 percent of the crop was reported.

The exploded.
The disease was reported for the first time in Israel in 40–39, the outbreak of the disease occurred in close proximity to the onset of the tobacco evasion. At the end of 1970, the outbreak of the disease in the country and caused 100 percent loss of crops in the tomato. The Israeli virus species is also observed in Egypt, probably Bell
