“…Essex is characterized as having purple flowers, gray pubescence, a group V maturity, average protein, oil, height and yield and is moderately susceptible to sudden death syndrome (SDS) (Fusarium solani f. sp. glycines nee F.virguliforme Aoki; Lightfoot et al 2005;Yesudas et al, 2013). Williams 82 was developed by the USDA-ARS and the Illinois Agricultural Experiment Station by combining four individual BC 6 F 3 plants selected after a series of backcrosses to 'Williams' to transfer the Rps1k gene from Kingwa (Bernard and Cremeens, 1988).…”

“…This study was conducted by testing plants of four soybean (Glycine max) genotypes with contrasting genes for resistance to soybean cyst nematode (LD00-2817P [Diers et al, 2010] and LDX01-1-65 [Diers et al, 2005]) or sudden disease syndrome caused by Fusarium virguliforme (Ripley [de Farias Neto et al, 2007] and EF59 [Lightfoot et al, 2005]), as well as the 97 F3:4 (here after called as F3) lines from a cross between LD00-2817P (Diers et al, 2010) and LDX01-1-65. The lines from the LD00-2817P by LDX01-1-65 cross are the same lines that were used to test combinations of soybean cyst nematode (Heterodera glycines Ichinohe) resistance genes from PI 437654, PI 88788, and Peking that were bred into LD00-2817 and from Glycine soja PI 468916 that were bred into LDX01-1-65 (Kim et al, 2011).…”

Identification of Quantitative Trait Loci Controlling Gene Expression during the Innate Immunity Response of Soybean

et al. 2011

Microbe-associated molecular pattern-triggered immunity (MTI) is an important component of the plant innate immunity response to invading pathogens. However, most of our knowledge of MTI comes from studies of model systems with relatively little work done with crop plants. In this work, we report on variation in both the microbe-associated molecular patterntriggered oxidative burst and gene expression across four soybean (Glycine max) genotypes. Variation in MTI correlated with the level of pathogen resistance for each genotype. A quantitative trait locus analysis on these traits identified four loci that appeared to regulate gene expression during MTI in soybean. Likewise, we observed that both MTI variation and pathogen resistance were quantitatively inherited. The approach utilized in this study may have utility for identifying key resistance loci useful for developing improved soybean cultivars.

“…The QTL could be assigned to linkage group U10b (Lark et al 1995) and the C1 linkage group of the composite soybean map (Song et al 2004). However, this locus might be the same as the QTL identified by A63I-1 in greenhouse assays of F. solani resistance in Essex by Forrest (ExF; Torto et al 1996;Lightfoot et al 2005).…”

“…Correlations of SDS resistance with planting date and morphological traits such as growth habit, maturity, leaf morphology and stem morphology are significant (Gibson et al 1994;Rupe et al 1994;Rupe and Gbur 1995;Njiti et al 1996Njiti et al , 2002. Therefore, resistance gene mapping studies must be carefully designed to exclude these sources of variability (Hnetkovsky et al 1996;Lightfoot et al 2005).…”

. 2006. Genetic analysis infers Dt loci underlie resistance to Fusarium solani f. sp. glycines in indeterminate soybeans. Can. J. Plant Sci. 86: 83-90. Improved resistant cultivars are being developed to better withstand the sudden death syndrome (SDS) of soybean (Glycine max L. Merr.) caused by Fusarium solani (Mart.) Sacc. f. sp. glycines (Fsg) (renamed F. virguliforme). Field trials to identify and select SDS-resistant cultivars take several years and are expensive. Selection of seedlings in the greenhouse and marker assisted selection are faster and cheaper. Selection for loci contributing SDS is well established for southern US germplasm sources (Forrest, Pyramid) but untested in northern germplasm. The aim was to find DNA markers associated with loci contributing seedling resistance to F. solani in the northern germplasm cultivars Minsoy and Noir. The greenhouse assay used plants grown for 3 wk in F.solani inoculated soil. Disease severity (DS) was recorded for 2000 recombinant inbred lines (RIL) from Minsoy × Noir1 (M×N) after F. solani infestation and compared to the DS of non-infested controls. Minsoy was partially resistant and Noir1 was relatively susceptible to F. solani. The heritability of DS was 48%. Comparison of alleles at 247 loci with the DS trait identified three regions associated with DS. Two regions within a 16 cM region of linkage group L (U14) were identified by markers SAT99 (P = 0.0006, R 2 = 7%) and SATT6 (P = 0.0013, R 2 = 5%). One region on linkage group C1 (U10b_ was identified by A063_1 (P = 0.0011, R 2 = 5%). Interacting loci explained an additional 12% (A280 and SAT99) and 10% (R28 and SATT6) of the variability in DS, mainly by increasing resistance in susceptible class at each quantitative trait loci (QTL). These loci jointly explain the major portion (34%) of heritable resistance to F.solani. The QTL did not correspond with the known loci that condition resistance in the field in southern US germplasm. The QTL were in regions of the genome that were previously determined to alter determinacy, plant morphology, leaf shape, stem thickness, plant height, maturity and water use. Here Minsoy was taller, had thicker stems, produced more root mass and more shoot mass than Noir 1 during Fsg infestation. Height (r = 0.15, P = 0.03), root weight (r = 0.3, P = 0.0002) and shoot weight (r = 0.4, P = 0.0001) were significantly negatively correlated with resistance to SDS. Therefore, we conclude the SDS resistance is a pleiotropic effect of shoot and root characters in Minsoy and Noir that may confound selection for resistance to SDS in North American germplasm. , ont été identifiées au moyen des marqueurs SAT99 (P = 0,0006, R 2 = 7 %) et SATT6 (P = 0,0013, R 2 = 5 %). Une zone sur le groupe de liaison C1 (U10b) a été identifiée avec le marqueur A063_1 (P = 0,0011, R 2 = 5 %). L'interaction des locus explique 12 % (A280 et SAT99) et 10 % (R28 et SATT6) de la variabilité du DGM de plus, principalement parce qu'elle accroît la résistance des plants susceptibles sur chaque QTL.
