Abstract

First report of Sugarcane mosaic virus infecting Columbus grass (Sorghum almum) in the United States.

Abstract

During the 2015 spring season, in a patch of Columbus grass (Sorghum almum) growing near a sugarcane field at Canal Point in Florida, USA, patterns of contrasting shades of green were observed on leaves of several plants. Ten of these plants with mosaic-looking symptoms were collected for further investigation. The causal pathogen was identified as Sugarcane mosaic virus (SCMV) based on serological and molecular analyses. This is thought to be the first report of the SMV on S. almum in the USA.
