Inducible Resistance to Maize Streak Virus
Maize streak virus (MSV), which causes maize streak disease (MSD), is the major viral pathogenic constraint on maize production in Africa. Type member of the Mastrevirus genus in the family Geminiviridae, MSV has a 2.7 kb, single-stranded circular DNA genome encoding a coat protein, movement protein, and the two replication-associated proteins Rep and RepA. While we have previously developed MS...
متن کاملReconstructing the history of Maize streak virus
64 65 Maize streak virus (MSV) strain A, the causal agent of Maize streak disease is 66 today one of the most serious biotic threats to African food security. Determining 67 where MSV-A originated and how it spread trans-continentally could yield 68 valuable insights into its historical emergence as a crop pathogen. Similarly, 69 determining where the major extant MSV-A lineages arose could ide...
متن کاملMaize fine streak virus, a New Leafhopper-Transmitted Rhabdovirus.
ABSTRACT A previously uncharacterized virus was isolated from fall-planted sweet corn (Zea mays L., Syngenta GSS 0966) leaves showing fine chlorotic streaks. Symptomatic plants were negative in enzyme-linked immunosorbent assay against many maize viruses, but reacted weakly with antisera to Sorghum stunt mosaic virus suggesting a distant relationship between the viruses. The virus was readily t...
متن کاملDating the origins of the maize-adapted strain of maize streak virus, MSV-A
Maize streak virus (MSV), which causes maize streak disease (MSD), is one of the most serious biotic threats to African food security. Here, we use whole MSV genomes sampled over 30 years to estimate the dates of key evolutionary events in the 500 year association of MSV and maize. The substitution rates implied by our analyses agree closely with those estimated previously in controlled MSV evo...
متن کاملStructure of the Maize streak virus geminate particle.
The Geminiviridae is an extensive family of plant viruses responsible for economically devastating diseases in crops worldwide. Geminiviruses package circular, single-stranded DNA (ssDNA) genomes. The characteristic twinned or "geminate" particles, which consist of two joined, incomplete T = 1 icosahedra, are unique among viruses. We have determined the first structure of a geminivirus particle...
