“…It has been reported that in addition to GmSNAP18, GmSNAP11 and GmSNAP14 were associated with QTL for resistance to SCN3839. GmSNAP02 was reported to be associated with QTL for resistance to Phytophtora 40. Moreover, GmSNAP02 RNAseq data (soybase RNAseq expression) show that its expression was confined only to flowers and seeds, and qRT-PCR data showed that GmSNAP02 had a very low expression in the roots, which suggests that it may have been subfunctionalized.…”

Proteins with Tetratricopeptide-repeat (TPR) domains are encoded by large gene families and distributed in all plant lineages. In this study, the Soluble NSF-Attachment Protein (SNAP) subfamily of TPR containing proteins is characterized. In soybean, five members constitute the SNAP gene family: GmSNAP18, GmSNAP11, GmSNAP14, GmSNAP02, and GmSNAP09. Recently, GmSNAP18 has been reported to mediate resistance to soybean cyst nematode (SCN). Using a population of recombinant inbred lines from resistant and susceptible parents, the divergence of the SNAP gene family is analysed over time. Phylogenetic analysis of SNAP genes from 22 diverse plant species showed that SNAPs were distributed in six monophyletic clades corresponding to the major plant lineages. Conservation of the four TPR motifs in all species, including ancestral lineages, supports the hypothesis that SNAPs were duplicated and derived from a common ancestor and unique gene still present in chlorophytic algae. Syntenic analysis of regions harbouring GmSNAP genes in soybean reveals that this family expanded from segmental and tandem duplications following a tetraploidization event. qRT-PCR analysis of GmSNAPs indicates a co-regulation following SCN infection. Finally, genetic analysis demonstrates that GmSNAP11 contributes to an additive resistance to SCN. Thus, GmSNAP11 is identified as a novel minor gene conferring resistance to SCN.

“…Several QTLs for partial resistance to P. sojae have been reported, and the molecular markers linked to the QTLs could be used for developing cultivars with partial resistance (Burnham et al 2003, Han et al 2008, Tucker et al 2010, Weng et al 2007). However, it is still difficult to integrate multiple QTLs at independent loci into a cultivar without some adverse effects.…”

Pathogenic diversity of Phytophthora sojae and breeding strategies to develop Phytophthora-resistant soybeans

Phytophthora stem and root rot, caused by Phytophthora sojae, is one of the most destructive diseases of soybean [Glycine max (L.) Merr.], and the incidence of this disease has been increasing in several soybean-producing areas around the world. This presents serious limitations for soybean production, with yield losses from 4 to 100%. The most effective method to reduce damage would be to grow Phytophthora-resistant soybean cultivars, and two types of host resistance have been described. Race-specific resistance conditioned by single dominant Rps (“resistance to Phytophthora sojae”) genes and quantitatively inherited partial resistance conferred by multiple genes could both provide protection from the pathogen. Molecular markers linked to Rps genes or quantitative trait loci (QTLs) underlying partial resistance have been identified on several molecular linkage groups corresponding to chromosomes. These markers can be used to screen for Phytophthora-resistant plants rapidly and efficiently, and to combine multiple resistance genes in the same background. This paper reviews what is currently known about pathogenic races of P. sojae in the USA and Japan, selection of sources of Rps genes or minor genes providing partial resistance, and the current state and future scope of breeding Phytophthora-resistant soybean cultivars.

“…Partial resistance was evaluated based on lesion length via root inoculation (tray test), and these two QTL explained a total of 42–50 % of the genotypic variance in each population (Burnham et al 2003). Han et al (2008) also identified QTL for partial resistance at similar locations on chromosomes 2 and 13 in a Conrad × OX760-6-1 (S) population using a different root inoculation procedure and isolates from Northeast China. Another QTL were mapped to chromosome 16 in Conrad × OX760-6-1 population based on the field-based disease incidence (Weng et al 2007).…”

Novel quantitative trait loci for partial resistance to Phytophthora sojae in soybean PI 398841

Phytophthora root and stem rot caused by Phytophthora sojae Kaufmann and Gerdemann is one of the most severe soybean [Glycine max (L.) Merr] diseases in the USA. Partial resistance is as effective in managing this disease as single-gene (Rps gene)-mediated resistance and is more durable. The objective of this study was to identify quantitative trait loci (QTL) associated with partial resistance to P. sojae in PI 398841, which originated from South Korea. A population of 305 F7:8 recombinant inbred lines derived from a cross of OX20-8 × PI 398841 was used to evaluate partial resistance against P. sojae isolate C2S1 using a tray test. Composite interval mapping using a genome-wide logarithm of odd (LOD) threshold detected three QTL on chromosomes 1, 13, and 18, which individually explained 4–16 % of the phenotypic variance. Seven additional QTL, accounting for 2–3 % of phenotypic variance each, were identified using chromosome-wide LOD thresholds. Seven of the ten QTL for resistance to P. sojae were contributed by PI 398841. Seven QTL co-localized with known Rps genes and previously reported QTL for soil-borne root pathogens, isoflavone, and seed oil. Three QTL on chromosomes 3, 13, and 18 co-localized with known Rps genes, but PI 398841 did not exhibit an Rps gene-mediated resistance response following inoculation with 48 different isolates of P. sojae. PI 398841 is potentially a source of novel genes for improving soybean cultivars for partial resistance to P. sojae.Electronic supplementary materialThe online version of this article (doi:10.1007/s00122-013-2040-x) contains supplementary material, which is available to authorized users.
