“…2b). All of these values exceed the criteria percentage, which in the case of potyviruses is 77 and 82 % identity at the nucleic acid and amino acid levels, respectively [36]. Thus, it can be concluded that these sequences are different isolates of the MDMV virus species.…”

Recombination among RNA viruses is a natural phenomenon that appears to have played a significant role in the species development and the evolution of many strains. It also has particular significance for the risk assessment of plants which have been genetically modified for disease resistance by incorporating viral sequences into their genomes. However, the exact recombination events taking place in viral genomes are not investigated in detail for many virus groups. In this analysis, different single-stranded positive-sense RNA potyviruses were compared using various in silico recombination detection methods and new recombination events in the Sugarcane mosaic virus (SCMV) subgroup were detected. For an extended in silico recombination analysis, two of the analyzed Maize dwarf mosaic virus full-length genomes were sequenced additionally during this work. These results strengthen the evidence that recombination is a major driving force in virus evolution, and the emergence of new virus variants in the SCMV subgroup, paired with mutations, could generate viruses with altered biological properties. The intra- and interspecific homolog recombinations seem to be a general trait in this virus group, causing little or no changes to the amino acid of the progenies. However, we found a few breakpoints between the members of SCMV subgroup and the weed-infecting distant relatives, but only a few methods of the RDP3 package predicted these events with low significance level.

“…Potyviridae family, and remains among the most harmful viruses causing diseases of maize in various regions of the world, mostly in some Asian and European countries (Gell et al, 2010). More recently, infections of Maize chlorotic mottle virus (MCMV) (genus Machlomovirus, family Tombusviridae), transmitted by thrips, have been important in some countries (Silva-Rosales et al, 2015;Wangai et al, 2012).…”

Los virus patógenos de plantas son importantes para la agricultura pues causan cuantiosas pérdidas económicas en el rendimiento y calidad de los cultivos. Estos pueden provocar infecciones simples o mixtas, interfiriendo con el desarrollo de las plantas. Las enfermedades ocasionadas por virus se encuentran a lo largo de zonas agrícolas de maíz en todo el mundo, y llegan a representar pérdidas significativas para los productores. Adicionalmente, el Corn stunt spiroplasma (CSS) es capaz de co-infectar plantas de maíz en conjunto con virus fitopatógenos, incrementando las pérdidas en este cultivo. En este estudio, con ensayos de DAS-ELISA, detectamos Maize dwarf mosaic virus (MDMV), Sugarcane mosaic virus (SCMV), Maize chlorotic mottle virus (MCMV), Maize stripe virus (MSpV), Brome mosaic virus (BMV), Maize white line mosaic virus (MWLMV), además del CSS, en infecciones simples y mixtas en el estado de Veracruz. Se identificaron más de cuatro virus distintos en infecciones mezcladas con el SCMV que fue el virus más frecuente, seguido por MDMV y CSS. Este es el primer reporte de infecciones simultáneas con más de dos virus, en plantas de maíz en México. Plant viruses are important agricultural pathogens because they cause significant losses in economic crop yield and quality. They can occur in single or mixed infections interfering with plant development. Diseases caused by these viruses are found throughout the maize-growing regions of the world and can cause significant losses for producers. Additionally, the Corn stunt spiroplasma (CSS) is able to co-infect maize plants together with phytopathogen viruses, increasing losses in this crop. In this study, using DAS-ELISA tests, we detected Maize dwarf mosaic virus (MDMV), Sugarcane mosaic virus (SCMV), Maize chlorotic mottle virus (MCMV), Maize stripe virus (MSpV), Brome mosaic virus (BMV), Maize white line mosaic virus (MWLMV), and CSS in single and mixed infections in a survey made in the State of Veracruz. Up to four different viruses were identified in mixed infections with Article Info/Información del artículo

“…These include Sorghum mosaic virus (SrMV) [ 6 , 7 ], Johnsongrass mosaic virus (JGMV) [ 8 ], Maize chlorotic mottle virus (MCMV), and Maize chlorotic dwarf virus (MCDV) [ 9 ]. Among all the maize-infecting viruses, Maize dwarf mosaic virus (MDMV) is the most common disease agent in this monocotyledonous crop globally [ 10 ], with incidences of maize dwarf mosaic (MDM) disease reported in Africa, United States, Asia and Europe [ 11 ].…”

Maize dwarf mosaic virus (MDMV) is a serious maize pathogen, epidemic worldwide, and one of the most common virus diseases for monocotyledonous plants, causing up to 70% loss in corn yield globally since 1960. MDMV belongs to the genus Potyvirus (Potyviridae) and was first identified in 1964 in Illinois in corn and Johnsongrass. MDMV is a single stranded positive sense RNA virus and is transmitted in a non-persistent manner by several aphid species. MDMV is amongst the most important virus diseases in maize worldwide. This review will discuss its genome, transmission, symptomatology, diagnosis and management. Particular emphasis will be given to the current state of knowledge on the diagnosis and control of MDMV, due to its importance in reducing the impact of maize dwarf mosaic disease, to produce an enhanced quality and quantity of maize.
