alfalfa (medicago sativa) is among a few of the most important forage crops for the growth of which hamedan province benefits from a suitable climate. alfalfa bacterial wilt disease induced by clavibacter michiganensis subsp. insidiosus cause substantial economic crop losses. this disease has not been so far investigated extensively in hamedan province. in the course of this survey affected pla...

In this study, it was aimed to reveal some viruses that are a problem in Dahlia plants grown for ornamental parks and home gardens Selçuklu, Karatay Meram districts of Konya. For reason, the 2019 summer, leaf samples were taken from 152 showing symptoms similar virus disease such as mosaic, deformations, yellowing, blight on leaves stunted plants. Possible infections Cucumber mosaic (CMV), Toma...

introduction: several potyviruses infecting gramineous plants have been reported from iran. mosaic is the most widespread viral disease affecting sugarcane and maize production. sugarcane mosaic virus (scmv) is one of the causal agents of mosaic disease, which was first described in ohio in 1963. scmv belonging to the genus potyvirus, family potyviridae, is a single-stranded positive sense rna ...

Hakkari ili domates ve biber üretim alanlarında lekeli solgunluk virüsü (Tomato spotted wilt virus, TSWV) yonca mozaik (Alfalfa mosaic AMV)’nün belirlenmesi için yapılan sürveyler 2020 döneminde gerçekleştirilmiştir. Domates sararma, nekroz, şekil bozukluğu simptomu gösteren 184 bitkiden yaprak örneği toplanmıştır. Toplanan örneklerinde TSWV AMV’nin Double antibody sandwich enzyme linked immuno...

Recently, we showed that the main determinant in the tRNA-like structure of turnip yellow mosaic virus RNA to initiate minus-strand synthesis in vitro is the 3' ACCA end. By mutational analysis of the 3'-terminal hairpin, we show here that only a non-base-paired ACCA end is functional and that the stability of the wild-type 3'-proximal hairpin is the most favorable, in that it has the lowest De...

Although the genetic organization of tobacco mosaic virus (TMV) differs considerably from that of the tripartite viruses (alfalfa mosaic virus [AlMV] and brome mosaic virus [BMV]), all of these RNA plant viruses share three domains of homology among their nonstructural proteins. One such domain, common to the AlMV and BMV 2a proteins and the readthrough portion of TMV p183, is also homologous t...

Information on genetic diversity and population structure of a tetraploid alfalfa collection might be valuable in effective use of the genetic resources. A set of 336 worldwide genotypes of tetraploid alfalfa (Medicago sativa subsp. sativa L.) was genotyped using 85 genome-wide distributed SSR markers to reveal the genetic diversity and population structure in the alfalfa. Genetic diversity ana...
