Genome Sequence of Euphorbia mosaic virus from Passionfruit and Euphorbia heterophylla in Florida

Abstract

Euphorbia mosaic virus (EuMV) was found in a symptomatic passionfruit (Passiflora edulis) plant from Homestead, Florida, USA, as well as in the symptomatic weed Euphorbia heterophylla. This is the first identification of EuMV in Florida and the United States and the first report of a natural infection of passionfruit by EuMV.

First report of squash leaf curl virus detected in Proboscidea louisianica in Mexico

“…The genus Begomovirus belongs to the Geminiviridae family, which is transmitted by the whitefly Bemisia tabaci (Al-Musa et al 2008). It causes significant losses and affects dicotyledonous plants of high-valued horticultural crops (Polston et al 2017). In addition to cultivated plants, begomoviruses are also found in weeds and wild plants.…”

“…The identification of alternative hosts (weeds) is essential to completely understand the epidemiology of these infectious agents in developing more effective integrated pest management strategies; however, the importance of weeds in the cycle of viral diseases has been largely overlooked (Leke et al 2015). Although recently, studies have been carried out on the begomoviruses that infect weeds (Polston et al 2017). According to Mubin et al (2010), weeds are reservoirs for begomovirus, they play a crucial role in the outbreak of epidemics that affect plants at the beginning of their cropping cycle.…”
