“…Using a large isogenic mapping population, Scmv2 was mapped to an interval of 1.34 Mb on chr 3, covering four predicted genes possibly involved in virus movement (Ingvardsen et al 2010). Later, Scmv2 was fine-mapped to an interval of 196.5 kb with two predicted genes, encoding an auxin-binding protein (ABP1) and a Rho GTPase-activating protein, as candidate genes for Scmv2 (Ding et al 2012). Candidate gene-based association mapping revealed a significantly associated marker 207FG003 in the Scmv2 region (Leng et al 2015).…”

Viruses cause significant diseases on maize worldwide. Intensive agronomic practices, changes in vector distribution, and the introduction of vectors and viruses into new areas can result in emerging disease problems. Because deployment of resistant hybrids and cultivars is considered to be both economically viable and environmentally sustainable, genes and quantitative trait loci for most economically important virus diseases have been identified. Examination of multiple studies indicates the importance of regions of maize chromosomes 2, 3, 6, and 10 in virus resistance. An understanding of the molecular basis of virus resistance in maize is beginning to emerge, and two genes conferring resistance to sugarcane mosaic virus, Scmv1 and Scmv2, have been cloned and characterized. Recent studies provide hints of other pathways and genes critical to virus resistance in maize, but further work is required to determine the roles of these in virus susceptibility and resistance. This research will be facilitated by rapidly advancing technologies for functional analysis of genes in maize.

“…This region contains Wsm2 and Scm2 (also known as Scmv2 or Rscmv2), genes that confer resistance to WSMV and SCMV. The same region includes enhancers of resistance to MDMV and other potyviruses (De Souza et al, 2008;Ding et al, 2012;Dussle et al, 2000;Jones et al, 2011;McMullen et al, 1994;Stewart, Haque, Jones, & Redinbaugh, 2013;Wang, Zhang, Zhuang, Qin, & Zhang, 2007;Zambrano, Jones, Brenner, et al, 2014;Zhang et al, 2003). The region also contains QTLs that confer resistance to the waikavirus MCDV, the negative sense RNA rhabdovirus MMV, the ambisense RNA tenuivirus MSpV, the single-stranded DNA geminivirus MSV, and the ambisense RNA virus WoMV (Dintinger, Verger, et al, 2005;Jones et al, 2004;Marçon, Kaeppler, & Jensen, 1997;Marçon, Kaeppler, Jensen, Senior, & Stuber, 1999;Ming et al, 1997;Welz et al, 1998;Zambrano, Jones, Brenner, et al, 2014).…”

“…None of the virus-resistance genes or loci mapped in genetic studies have been isolated to date, but recent reports describe fine mapping of genomic regions carrying the Scmv1 and Scm1/Scmv2/Rscmv2 genes that confer resistance to SCMV (Ding et al, 2012;Ingvardsen, Xing, Frei, & Lubberstedt, 2010;Tao, Jiang, et al, 2013). Tao and coworkers (2013) narrowed Scmv1 to a region corresponding to a 59 kb of chr.…”

“…Of particular interest are genes previously associated with pathogen and abiotic stress responses such as putative thioredoxin h and cycloartenol synthase genes.Fine mapping of the Scmv2 and Rscmv2 genes identified a region of chr. 3 corresponding to 1.34 Mb (Ingvardsen et al, 2010) or 196 kb (Ding et al, 2012) of the B73 genome, respectively. Of the 20 ESTs homologous to portions of the Scmv2 region, those similar to heat-shock protein 70, general vesicular transport factor p115, RhoGTPase-activating proteins and syntaxin proteins were considered candidate genes based on their involvement in plant responses to various stimuli (Ingvardsen et al, 2010).…”

“…eIF4e has also been shown to move from cell to cell, and some eIF4e alleles do not allow cell-to-cell movement of the potyvirus, Pea seedborne mosaic virus (Gao et al, 2004). However, these eIF4e genes are not within the Scmv2/Rscmv2 regions identified in fine-mapping studies (Ding et al, 2012;Ingvardsen et al, 2010), so further research is needed to determine if the translation factors have any effect on virus resistance in maize.…”

Genetic analysis of resistance to six virus diseases in a multiple virus-resistant maize inbred line

et al. 2014

Novel and previously known resistance loci for six phylogenetically diverse viruses were tightly clustered on chromosomes 2, 3, 6 and 10 in the multiply virus-resistant maize inbred line, Oh1VI. Virus diseases in maize can cause severe yield reductions that threaten crop production and food supplies in some regions of the world. Genetic resistance to different viruses has been characterized in maize populations in diverse environments using different screening techniques, and resistance loci have been mapped to all maize chromosomes. The maize inbred line, Oh1VI, is resistant to at least ten viruses, including viruses in five different families. To determine the genes and inheritance mechanisms responsible for the multiple virus resistance in this line, F1 hybrids, F2 progeny and a recombinant inbred line (RIL) population derived from a cross of Oh1VI and the virus-susceptible inbred line Oh28 were evaluated. Progeny were screened for their responses to Maize dwarf mosaic virus, Sugarcane mosaic virus, Wheat streak mosaic virus, Maize chlorotic dwarf virus, Maize fine streak virus, and Maize mosaic virus. Depending on the virus, dominant, recessive, or additive gene effects were responsible for the resistance observed in F1 plants. One to three gene models explained the observed segregation of resistance in the F2 generation for all six viruses. Composite interval mapping in the RIL population identified 17 resistance QTLs associated with the six viruses. Of these, 15 were clustered in specific regions of chr. 2, 3, 6, and 10. It is unknown whether these QTL clusters contain single or multiple virus resistance genes, but the coupling phase linkage of genes conferring resistance to multiple virus diseases in this population could facilitate breeding efforts to develop multi-virus resistant crops.
