First Report of Strawberry as a Natural Host of Apple mosaic virus

Abstract

Apple mosaic virus (ApMV) has been reported to naturally infect a number of hosts in the Rosaceae family including Rosa spp., Malus spp., and Rubus spp. etc., as well as several hosts such as Humulus spp. and Betula spp. in other plant families (2), but has not been reported to naturally infect Fragaria spp. although it has been grafted into Fragaria spp. (1). In an attempt to develop a detection method for strawberry leafroll as part of an overall strategy to develop diagnostics for all reported virus and virus-like diseases of strawberry, double-stranded RNA (dsRNA) was extracted and cloned as described elsewhere (3) from a single-leafroll-infected plant of Fragaria vesca 'UC-5' (CFRA no. 9026 maintained at the USDA-ARS National Clonal Germplasm Repository [NCGR] in Corvallis, OR). Newer leaves on the plant had a chlorotic peacock pattern with a few leaves exhibiting a downward leafroll. The dsRNA pattern suggested possible infection with a crinivirus and an ilarvirus. A database search (BLAST at the National Center for Biotechnology Information) showed that clones with sequence homology to two criniviruses (Strawberry pallidosis associated virus [SPaV] and Beet pseudo-yellows virus [BPYV] as well as ApMV) were obtained from ...Continue Reading

Birth Defects

Birth defects encompass structural and functional alterations that occur during embryonic or fetal development and are present since birth. The cause may be genetic, environmental or unknown and can result in physical and/or mental impairment. Here is the latest research on birth defects.
