Project description:Soybean nested association mapping (NAM) parent lines were compared by CGH to catalog structurally variant (e.g. deletion and duplication) regions among these genotypes. The CGH comparisons reveal reveal putative deletions and duplications among the 41 lines. NAM parent lines were compared through a common reference, Wm82-ISU-01 (this is a sub-line isolated from the cultivar Williams 82 stock). Each NAM parent line was represented by a single individual plant. The reported values show the log2 ratio of the normalized NAM parent line hybridization signals (Cy3) over the normalized Wm82-ISU-01 hybridization signal (Cy5).

Project description:CGH was used to compare structural variation among four soybean cultivars (Archer, Minsoy, Noir1 and Williams 82). Four additional hybridizations were performed with these and other accessions (Kingwa, Williams, M92-220, Richland and Essex) to confirm the patterns observed.

Project description:Transgenic soybean lines were compared to their parental lines by CGH to catalog structurally variant (e.g. deletion and duplication) regions among these genotypes. The CGH comparisons reveal reveal putative deletions and duplications among the 5 lines.

Project description:CGH was used to compare structural variation among four soybean cultivars (Archer, Minsoy, Noir1 and Williams 82). Three different soybean cultivars (Archer, Minsoy and Noir1) were hybridized against the common reference genotype Williams 82. The soybean tiling array consists of 700k probes, spaced at approximately 1.1 kb intervals.

Project description:Soybean is a self-pollinating crop species that has relatively low nucleotide polymorphism rates compared to other crop plant species. Despite the appearance of a low intervarietal nucleotide polymorphism rate, a wide range of heritable phenotypic variation exists. There is even evidence for heritable phenotypic variation among individuals within some varieties. ‘Williams 82,’ the soybean variety used to produce the reference genome sequence, was derived from backcrossing a phytophthora root rot resistance locus from the donor parent ‘Kingwa’ into the recurrent parent ‘Williams.’ To explore the genetic basis of intravarietal variation, we investigated the nucleotide, structural and gene content variation of different Williams 82 individuals. Williams 82 individuals exhibited variation in the number and size of introgressed Kingwa loci. In these regions of genomic heterogeneity, the reference Williams 82 genome sequence consists of a mosaic of Williams and Kingwa haplotypes. Genomic structural variation between Williams and Kingwa was maintained between the Williams 82 individuals within the regions of heterogeneity. Additionally, the regions of heterogeneity exhibited gene content differences between Williams 82 individuals. Collectively, these findings show that genetic heterogeneity in Williams 82 primarily originated from the differential segregation of polymorphic chromosomal regions following the backcross and single-seed descent generations of the breeding process. We conclude that soybean haplotypes can possess a high rate of structural and gene content variation, and the impact of intravarietal genetic heterogeneity may be much greater than previously assumed. This detailed characterization will be useful for interpreting soybean genomic data sets and highlights important considerations for research communities that are utilizing or working towards developing a reference genome sequence. Soybean variety Williams 82 (Wm82) was derived from a Williams x Kingwa BC6F3 population. CGH was performed to detect regions of Kingwa genomic introgression in Wm82; Williams was hybridized as a common reference against Kingwa and four different Wm82 individuals. Two different Wm82 individuals (SGC and ISU) were also hybridized with one another. The soybean tiling array consists of 700k probes, spaced at approximately 1.1 kb intervals.

Project description:GmMPK4 silencing was performed in Glycine max (Williams 82) using virus-induced gene silencing (VIGS) mediated by Bean pod mottle virus (BPMV). Microarray analysis was performed to compare the transcriptional profile of GmMPK4-silenced plants vs vector control plants. ****[PLEXdb(http://www.plexdb.org) has submitted this series at GEO on behalf of the original contributor, Jianzhong Liu. The equivalent experiment is GM25 at PLEXdb.] genotype: Williams 82(4-replications) genotype: GmMPK4-silenced Williams 82(4-replications)
