• 2 DNA Markers in 1 test
• Faster results at lower cost

The L4 marker is a genetic indicator for plant resistance to mild mottle virus (PMMoV), a tobamovirus known to cause necrosis of the fruit and mottling of the leaves. Tobamoviruses spread across a crop of susceptible pepper plants via soil contamination, irrigation and seed transmission. With many routes of transfer, farmers may struggle to control an outbreak, causing devastating crop loss. The L4 allele induces a cellular response in an infected cell, preventing the virus from spreading into adjacent healthy cells and the rest of the plant.

The presence of the TSW gene indicates resistance to Tospovirus Tomato Spotted Wilt Virus (TSWV). Tomato spotted wilt virus affects many plant types, including peppers. TSWV spreads through infected thrip larvae feeding on the plant tissue. The virus can then spread between plants through wind dispersion and/or physical transfer of infected plant material or larvae. This virus causes chlorotic lesions on leaves, leading to necrosis of leaves and shoots, and eventually severe discoloration on the fruit. Testing seeds for the TSW marker greatly reduce the possibility of significant crop loss due to a Tomato spotted wilt virus outbreak.

Previously, only separate genotyping tests were available for these common diseases, but today DYN R&D’s Genotype Duplex Marker Test combines both the L4 and TSW markers, bringing customers more efficient results at lower cost.
