“…The QTLs detected in this study are located in similar genomic regions as Rag1 on chromosome 7 (Li et al 2007, Kim et al 2010 and Rag3 on chromosome 16 (Zhang et al 2010). Although the two resistant genes in PI 567598B were considered recessive (Mensah et al 2008), and Rag1 or Rag3 was considered dominant or co-dominant (Hill et al 2006a;Zhang et al 2010), they may still be the same genes as Rag1 and Rag3, since the susceptible parent in this study was different from the ones used for characterizing Rag1 and Rag3. It is also possible that the two genes discovered in this study are allelic to Rag1 or Rag3, or different genes, but tightly linked to Rag1 or Rag3.…”

“…Genetic studies have shown that the antibiosis resistance in Dowling and Jackson were both controlled by a single dominant gene (Hill et al 2006a, b). The gene in Dowling was named Rag1 (Hill et al 2006a). Later, Rag1 and the resistance gene (Rag) in Jackson were both mapped in the same genomic region on chromosome 7 [linkage group (LG) M] (Li et al 2007).…”

The soybean aphid (Aphis glycines Matsumura) has been a major pest of soybean [Glycine max (L.) Merr.] in North America since it was first reported in 2000. Our previous study revealed that the strong aphid resistance of plant introduction (PI) 567598B was controlled by two recessive genes. The objective of this study was to locate these two genes on the soybean genetic linkage map using molecular markers. A mapping population of 282 F 4:5 lines derived from IA2070 9 E06902 was evaluated for aphid resistance in a field trial in 2009 and a greenhouse trial in 2010. Two quantitative trait loci (QTLs) were identified using the composite and multiple interval mapping methods, and were mapped on chromosomes 7 (linkage group M) and 16 (linkage group J), respectively. E06902, a parent derived from PI 567598B, conferred resistance at both loci. In the 2010 greenhouse trial, each of the two QTLs explained over 30 % of the phenotypic variation. Significant epistatic interaction was also found between these two QTLs. However, in the 2009 field trial, only the QTL on chromosome 16 was found and it explained 56.1 % of the phenotypic variation. These two QTLs and their interaction were confirmed with another population consisting of 94 F 2:5 lines in the 2008 and 2009 greenhouse trials. For both trials in the alternative population, these two loci explained about 50 and 80.4 % of the total phenotypic variation, respectively. Our study shows that soybean aphid isolate used in the 2009 field trial defeated the QTL found on chromosome 7. Presence of the QTL on chromosome 16 conferred soybean aphid resistance in all trials. The markers linked to the aphid-resistant QTLs in PI 567598B or its derived lines can be used in marker-assisted breeding for aphid resistance.

“…Recently, plant resistance has gained attention as a viable management option. Soybeans that exhibit antibiosis, antixenosis, and tolerance have been identified (Hill et al 2004(Hill et al , 2006aMensah et al 2005;Diaz-Montano et al 2006;Kang et al 2008;Mian et al 2008;Pierson et al 2010;Prochaska et al 2013).

Prochaska, Travis J.; Donze-Reiner, Teresa; Marchi-Werle, L.; Palmer, N. A.; Hunt, Thomas E.; Sarath, Gautam; and Heng-Moss, Tiffany, "Transcriptional responses of tolerant and susceptible soybeans to soybean aphid (Aphis glycines Matsumura) herbivory" (2015). Abstract The soybean aphid, Aphis glycines Matsumura, was introduced in 2000 to North America and has become one of the most significant pests to soybean, Glycine max (L.) Merrill, production. Possible solutions to this problem are the use of resistant plants and the understanding of the genes involved in plant resistance. In this study, we sought to better understand the genes involved in the tolerance response of soybean plants to the soybean aphid, utilizing tolerant (KS4202) and susceptible (K-03-4686) plants. Studies were conducted under greenhouse conditions. Leaf samples of both tolerant and susceptible plants were collected at day 5 and day 15 after infestation and analyzed by sequencing-by-synthesis on an Illumina GA II X instrument. In the tolerant genotype, 3 and 36 genes were found to be differentially expressed in the infested plants compared to the control treatments at day 5 and day 15, respectively. A similar comparison in the susceptible genotype revealed 0 and 11 genes to be differentially expressed at day 5 and day 15, respectively. Predominately, genes related to plant defense, such as WRKY transcription factors, peroxidases, and cytochrome p450s, were upregulated in the tolerant genotype 15 days post-infestation by aphids. In contrast, none of these genes were similarly up-regulated in the susceptible plants, suggesting that consistent elevation of defense responses is important to plant tolerance. However, significant genotypic differences in global gene expression were also found when transcriptomes from control uninfested plants were compared at both day 5 and 15. qPCR validation of select genes confirmed our RNA-seq data. These comparisons indicate that potentially broader regulation of transcriptomes also contributes to the tolerance response and provides data that the tolerant genotype (KS4202) could be useful in soybean breeding programs trying to minimize production losses accruing from soybean aphid feeding.

“…Hill et al (2004) characterized the Dowling, Jackson, and PI 71,506 soybean varieties as being resistant to soybean aphid. Hill et al (2004Hill et al ( , 2006 also described the source of resistance in Dowling as a single, dominant gene that they designated Rag1. While expression of Rag1 produces antibiosis against the soybean aphid, the exact mechanism of this resistance is currently unknown.…”

Effects of <I>Rag1</I> on the Preference and Performance of Soybean Defoliators

The Rag1 gene confers antibiotic resistance to soybean aphid, Aphis glycines Matsumura (Hemiptera: Aphididae), and in 2010, varieties expressing Rag1 were released for commercial use in the United States. We do not know how Rag1 varieties will influence the broader community of defoliating insects that inhabit soybean fields. In 2010 and 2011, the preference and performance of pest insects that defoliate soybeans [Glycines max (L.) Merr] were tested using Rag1 and aphidsusceptible varieties. Three coleopterans and four lepidopterans were used: northern corn rootworm, Diabrotica barberi Smith & Lawrence (Coleoptera: Chrysomelidae); southern corn rootworm, Diabrotica undecimpunctata howardi Barber (Coleoptera: Chrysomelidae); bean leaf beetle, Ceratoma trifurcata Förster (Coleoptera: Chrysomelidae); fall armyworm, Spodoptera frugiperda ( J. E. Smith) (Lepidoptera: Noctuidae); corn earworm, Helicoverpa zea (Boddie) (Lepidoptera: Noctuidae); soybean looper, Chrysodeix includens (Walker) (Lepidoptera: Noctuidae); and velvetbean caterpillar,Anticarsia gemmatalis Hübner (Lepidoptera: Noctuidae). The preference of insects was evaluated in choice and no-choice tests using Rag1 and susceptible soybeans. Lepidopterans also were evaluated on Rag1 leaves using four nutritional indices: relative growth rate, approximate digestibility, and efficiency of conversion of ingested material. In the majority of preference tests, no effect of Rag1 was detected, and in cases where preferences were found, there was no consistent pattern of preference for Rag1 vs. susceptible leaf tissue. Helicoverpa zea demonstrated a preference for resistant leaf tissue, but this was dependent on the genetic background of the variety. Evaluations of nutritional indices indicated that three species of Lepidoptera, S. frugiperda, H. zea, and A. gemmatalis, displayed reduced conversion efficiency for Rag1 soybeans, suggesting effects of antibiosis.
