Key message This review provides a comprehensive atlas of QTLs, genes, and alleles conferring resistance to 28 important diseases in all major soybean production regions in the world. Abstract Breeding disease-resistant soybean [Glycine max (L.) Merr.] varieties is a common goal for soybean breeding programs to ensure the sustainability and growth of soybean production worldwide. However, due to global climate change, soybean breeders are facing strong challenges to defeat diseases. Marker-assisted selection and genomic selection have been demonstrated to be successful methods in quickly integrating vertical resistance or horizontal resistance into improved soybean varieties, where vertical resistance refers to R genes and major effect QTLs, and horizontal resistance is a combination of major and minor effect genes or QTLs. This review summarized more than 800 resistant loci/alleles and their tightly linked markers for 28 soybean diseases worldwide, caused by nematodes, oomycetes, fungi, bacteria, and viruses. The major breakthroughs in the discovery of disease resistance gene atlas of soybean were also emphasized which include: (1) identification and characterization of vertical resistance genes reside rhg1 and Rhg4 for soybean cyst nematode, and exploration of the underlying regulation mechanisms through copy number variation and (2) map-based cloning and characterization of Rps11 conferring resistance to 80% isolates of Phytophthora sojae across the USA. In this review, we also highlight the validated QTLs in overlapping genomic regions from at least two studies and applied a consistent naming nomenclature for these QTLs. Our review provides a comprehensive summary of important resistant genes/QTLs and can be used as a toolbox for soybean improvement. Finally, the summarized genetic knowledge sheds light on future directions of accelerated soybean breeding and translational genomics studies.

“…Overall, this study confirmed resistance to virulent SCN in early maturity germplasm and identified new markers for breeding. Another exciting study identified a novel QTL (LG O) in soybean cultivar Pingliang demonstrating a type of resistance distinct from Peking and PI 88,788 [ 59 ]. Pingliang carries the low copy rhg1-a allele along with the susceptible Rhg4 haplotype which led the authors to believe that a major novel locus was responsible for its resistance to SCN.…”

Plant pathogens greatly impact food security of the ever-growing human population. Breeding resistant crops is one of the most sustainable strategies to overcome the negative effects of these biotic stressors. In order to efficiently breed for resistant plants, the specific plant–pathogen interactions should be understood. Soybean is a short-day legume that is a staple in human food and animal feed due to its high nutritional content. Soybean cyst nematode (SCN) is a major soybean stressor infecting soybean worldwide including in China, Brazil, Argentina, USA and Canada. There are many Quantitative Trait Loci (QTLs) conferring resistance to SCN that have been identified; however, only two are widely used: rhg1 and Rhg4. Overuse of cultivars containing these QTLs/genes can lead to SCN resistance breakdown, necessitating the use of additional strategies. In this manuscript, a literature review is conducted on research related to soybean resistance to SCN. The main goal is to provide a current understanding of the mechanisms of SCN resistance and list the areas of research that could be further explored.

“…2 Two major QTLs, rhg1 (Peking-type rhg1-a and PI88788-type rhg1-b ) and Rhg4 ( GmSHMT08 ), were cloned and functionally analyzed ( Cook et al, 2012 ; Liu et al, 2012 ; Liu et al, 2017 ). Three genes ( Glyma.18G022500 , Glyma.18G022500 , and Glyma.18G022700 ) around the rhg1-b locus and the gene GmSHMT ( Glyma.08G108900 ) around the Rhg4 locus were identified as major-effect gene to SCN resistance ( Cook et al, 2012 ; Liu et al, 2012 ; Guo et al, 2020 ). The PI88788-type requires at least 5.6 copies of rhg1-b ( Cook et al, 2012 ; Patil et al, 2019 ), whereas the Peking-type requires rhg1-a and Rhg4 for SCN resistance ( Patil et al, 2019 ).…”

“…For breeding resistant cultivars, it is vital to identify new quantitative trait loci (QTL) and genes underlying resistance ( Liu et al, 2019 ) and to broaden the genetic basis for improving soybeans’ resistance to SCN. In recent years, Numerous researchers have identified genes ( Guo et al, 2020 ) and reveled a complex regulatory network involved in SCN resistance ( Guo et al, 2020 ; Kofsky et al, 2021 ; Shi et al, 2021 ).…”

Soybean cyst nematode (SCN; Heterodera glycines Ichinohe) is a highly destructive pathogen for soybean production worldwide. The use of resistant varieties is the most effective way of preventing yield loss. Handou 10 is a commercial soybean variety with desirable agronomic traits and SCN resistance, however genes underlying the SCN resistance in the variety are unknown. An F2:8 recombinant inbred line (RIL) population derived from a cross between Zheng 9525 (susceptible) and Handou 10 was developed and its resistance to SCN HG type 2.5.7 (race 1) and 1.2.5.7 (race 2) was identified. We identified seven quantitative trait loci (QTLs) with additive effects. Among these, three QTLs on Chromosomes 7, 8, and 18 were resistant to both races. These QTLs could explain 1.91–7.73% of the phenotypic variation of SCN’s female index. The QTLs on chromosomes 8 and 18 have already been reported and were most likely overlapped with rhg1 and Rhg4 loci, respectively. However, the QTL on chromosome 7 was novel. Candidate genes for the three QTLs were predicted through genes functional analysis and transcriptome analysis of infected roots of Handou 10 vs. Zheng 9525. Transcriptome analysis performed also indicated that the plant–pathogen interaction played an important role in the SCN resistance for Handou 10. The information will facilitate SCN–resistant gene cloning, and the novel resistant gene will be a source for improving soybeans’ resistance to SCN.
