  • Title: Multiplexed RT-PCR for streamlined detection and separation of barley and cereal yellow dwarf viruses.
    Author: Malmstrom CM, Shu R.
    Journal: J Virol Methods; 2004 Sep 01; 120(1):69-78. PubMed ID: 15234811.
    Abstract:
    Two novel multiplexed RT-PCR assays that can efficiently detect and distinguish among different barley and cereal yellow dwarf viruses (B/CYDVs) are described. The basic multiplex can produce two fragments simultaneously, a approximately 830-bp fragment indicating the presence of the BYDV-PAV, BYDV-MAV, or BYDV-SGV viruses and a approximately 372-bp fragment indicating the presence of the CYDV-RPV, BYDV-RMV, or BYDV-GPV viruses. The enhanced multiplex produces two additional fragments, which further differentiate between BYDV-PAV, BYDV-MAV, and BYDV-SGV. These assays fulfill the critical need for a streamlined diagnostic procedure for B/CYDVs that can be cost-effectively applied to large numbers of small samples. The assays are useful not only in the basic diagnosis of B/CYDVs, but also for studies examining the ecological roles of B/CYDVs in natural systems and for longer-term epidemiological studies of grasses and cereals.
