“…Similarly, when germinating kernels of Pa405 were inoculated with MDMV by VPI, bright mosaic symptoms developed and MDMV antigen could be detected in leaves that were present in the embryo at the time of inoculation, but no systemic infection occurred (Cassone et al, 2014;Louie & Abt, 2004). Together, these data indicate that MDMV can replicate and move from cellto-cell in leaves of resistant plants, but that a barrier to systemic virus movement is present in resistant plants.…”

“…Another emerging area of research is to deploy vector-resistant crops, and maize inbred lines with resistance to P. maidis, C. mbila, and the aphid Rhopalosiphum maidis (Fitch) have been characterized (Dintinger, Boissot, Chiroleu, Hamon, & Reynaud, 2005;Dintinger, Verger, et al, 2005;Jones, 2006;Kairo, Kiduyu, Mutinda, & Empig, 1995;So, Ji, & Brewbaker, 2010). The rapidly developing genome information on maize virus vectors is expected to be key to identifying targets for development of vector-resistant maize (Cassone, Chen, Chiera, Stewart, & Redinbaugh, 2014;Chen, Cassone, Bai, Redinbaugh, & Michel, 2012;Whitfield, Rotenberg, Aritua, & Hogenhout, 2011). …”

“…Relatively few transcripts were upregulated in virus-resistant maize lines inoculated with potyviruses (Cassone et al, 2014;Shi, Thummler, Melchinger, Wenzel, & Lubberstedt, 2006;Uzarowska et al, 2009), but more were identified in the proteomic analyses (Wu, Han, et al, 2013;. The responses of susceptible maize lines to inoculation with RBSDV were also investigated ( Jia et al, 2012).…”

“…The responses of susceptible maize lines to inoculation with RBSDV were also investigated ( Jia et al, 2012). In the resistant inbred line Pa405 inoculated with MDMV, two transcripts annotated as potentially involved in virus resistance, pathogen response, or stress response were upregulated: an Hsp20/alpha crystalline-like gene and a cytochrome P450 (Cassone et al, 2014). Further, nine transcripts with putative involvement in signal transduction were identified as upregulated in MDMVinoculated plants.…”

“…Increased accumulation of a transcript with similarity to both an LRR receptor protein kinase (brassinosteroid-insensitive 1 in rice) and an Hsp20/alpha crystalline-like gene was identified in MDMV-inoculated plants and was also upregulated RBSDV-infected maize ( Jia et al, 2012). Different genes encoding homologous remorin proteins were upregulated in resistant and susceptible MDMV-inoculated plants (Cassone et al, 2014), and another remorin protein accumulated in SCMV-inoculated Mo17 (susceptible) plants, but not in the resistant line Siyi (Wu, Han, et al, 2013).…”

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.

The Asian rice gall midge, Orseolia oryzae, is a serious insect pest causing extensive yield loss. Interaction between the gall midge and rice genotypes is known to be on a gene-for-gene basis. Here, we report molecular basis of HR- (hypersensitive reaction-negative) type of resistance in Aganni (an indica rice variety possessing gall midge resistance gene Gm8) through the construction and analysis of a suppressive subtraction hybridization (SSH) cDNA library. In all, 2,800 positive clones were sequenced and analyzed. The high-quality ESTs were assembled into 448 non-redundant gene sequences. Homology search with the NCBI databases, using BlastX and BlastN, revealed that 73% of the clones showed homology to genes with known function and majority of ESTs belonged to the gene ontology category 'biological process'. Validation of 27 putative candidate gall midge resistance genes through real-time PCR, following gall midge infestation, in contrasting parents and their derived pre-NILs (near isogenic lines) revealed induction of specific genes related to defense and metabolism. Interestingly, four genes, belonging to families of leucine-rich repeat (LRR), heat shock protein (HSP), pathogenesis related protein (PR), and NAC domain-containing protein, implicated in conferring HR+ type of resistance, were found to be up-regulated in Aganni. Two of the reactive oxygen intermediates (ROI)-scavenging-enzyme-coding genes Cytosolic Ascorbate Peroxidase1, 2 (OsAPx1 and OsAPx2) were found up-regulated in Aganni in incompatible interaction possibly suppressing HR. We suggest that Aganni has a deviant form of inducible, salicylic acid (SA)-mediated resistance but without HR.
