Abstract An outbreak of a new disease infecting tomatoes occurred in October-November 2014 at the Ohad village in Southern Israel. Symptomatic plants showed a mosaic pattern on leaves accompanied occasionally Atrial Natriuretic Factor (1-29), chicken by narrowing of leaves and yellow spotted fruit. The disease spread mechanically and rapidly reminiscent of tobamovirus infection. Epidemiological studies showed the spread of the disease in various growing areas, in the South and towards the Southeast and Northern parts of the country within a year. Transmission electron microscope (TEM) analysis showed a Atrial Natriuretic Factor (1-29), chicken single rod-like form characteristic to the genus. We confirmed Kochs postulates for the disease followed by partial host range determination and revealed that tomato cultivars certified to harbor the resistance gene are susceptible to the new viral disease. We further characterized the viral source of the disease using a range of antisera for serological detection and analyzed various virus genera and families for cross-reactivity with the virus. In addition, next generation sequencing of total small RNA was performed on two cultivars grown in two different locations. In samples collected from commercial cultivars across Israel, we found a Atrial Natriuretic Factor (1-29), chicken single virus that caused the disease. The complete genome sequence of the new Israeli tobamovirus showed high sequence identity to the Jordanian isolate Rabbit Polyclonal to NCR3 of tomato brown rugose fruit virus. Introduction Tomato plants (and genus is the largest genus (35 species) among the seven genera in the family genus includes the well-known species the type member (TMV)  and the (ToMV) as well as (TMGMV) and (PMMoV) among the viruses capable of infecting crops [4, 5]. are characterized by a typical rod-shaped particle morphology encapsulating a single stranded RNA (+ssRNA) sense genome of 6.2 to 6.4kb encoding four ORFs. ORF1 and ORF2 are separated by a leaky stop codon and encode non-structural proteins that form the replicase complex. ORF3 on the large subgenomic RNA encodes the non-structural movement protein (MP). ORF4 on the small subgenomic RNA encodes the coat protein (CP) of 17 to 18 kDa. Tobamoviruses are transmitted by mechanical contact: through workers’ hands, clothes, tools, and are capable to preserve infectivity in seeds and contaminated soil [6, 7]. In tomatoes, dominant resistance introduced by introgression resulted in resistance to TMV and ToMV by the R genes and and resistances share the viral MP as the protein (Avr). However, different domains in the MP and different protein structure requirements are necessary for each resistance [10, 13C15]. The resistance has been more durable than the resistance rises since new tobamoviruses infecting tomatoes were identified. In Mexico, a tobamovirus named (ToMMV)  and in Jordan a tobamovirus putatively named tomato brown rugose fruit virus (TBRFV-Jo). ToMMV causes tissue necrosis of the leaves of tomato seedlings and mosaic and leaf distortion of mature plants. TBRFV-Jo causes mild foliar symptoms but brown rugose symptoms on fruits. Here we describe an outbreak of a disease, which occurred in October to November 2014 in tomato crops of cultivars (cvs.) Mose and Ikram in Israel non-grafted or grafted on rootstock cv. Arnold, grown in six 50-mesh.
