First report of maize yellow mosaic virus infecting maize in Ecuador.

Abstract:

Maize yellow mosaic virus (MaYMV) was first described in maize (Zea mays) from China and proposed as a new virus in the genus Polerovirus (Chen et al., 2016). Recently, MaYMV was also detected in symptomatic maize plants in Burkina Faso (Palanga et al., 2017) indicating a global distribution for the virus. In May 2016 maize plants showing leaf chlorosis and downward curling of leaf tips were collected from a large production area (c. 125,000 hectares in maize cultivation) in the Los Rios Province in Ecuador. It has been estimated that the disease causes yield losses of 10-30%. Total RNA from symptomatic leaf samples was extracted using the RNeasy Plant Mini Kit (Qiagen, USA) and subjected to deep sequencing analysis using the Illumina platform. Quality filtered paired end reads (8,777,028) were aligned with reference genomes of known plant viruses using standard bioinformatic tools. The transcriptome …
