Structural Modeling of Protein–DNA Interactions Underlying Genome Copy Number Variation in Nanoviruses

Aamir Lal, Myeonghwan Kwak, DR MUHAMMAD AMIR QURESHI, Sukchan Lee et autres

Multipartite nanoviruses possess multiple segmented genomes that accumulate at unequal levels during infection, giving rise to dynamic genome formulas. Although the replication of all segments relies on a common replication-associated protein (Rep), the molecular basis underlying segment-specific differences in genome abundance remains …

Construction and Segmental Reconstitution of Full-Length Infectious Clones of Milk Vetch Dwarf Virus

Aamir Lal, Muhammad Ali Amir, Man-Cheol Son, Sukchan Lee et autres

The construction of infectious clones (ICs) is essential for studying viral replication, pathogenesis, and host interactions. Milk vetch dwarf virus (MDV), a nanovirus with a multipartite, single-stranded DNA genome, presents unique challenges for IC development due to its segmented genome organization. To …

Regulatory role of stem-loop structures in Faba bean necrotic yellows virus replication efficiency

Muhammad Ali Amir, Muhammad Hassan Butt, Aamir Lal, Thuy Thi Bich Vo et autres

is a family of multipartite single-stranded DNA (ssDNA) plant viruses that encapsidate approximately 1 kb ssDNA segments individually and transmit them via aphids in a circulative, non-propagative manner. Nanoviruses cause significant diseases in host plants, particularly in leguminous crops. Each segment of …
