Project description:Two Near Isogenic soybean (Glycine max) lines were grown in hydroponic conditions with either 50uM ferric nitrate or 100uM ferric nitrate. After 10 days, half the plants were harvested (total root tissue). At 12 days after planting, iron was added to plants grown in low iron conditions bringing them up to sufficient iron growth conditions. Root tissue was harvested for the remaining plants at 14 days after planting. Gene expression analysis from root tissue of two Near Isogenic Lines (NILs), Clark (PI548553) and IsoClark (PI547430), grown in iron stress or iron stress recovered conditions.

Project description:Cytosine methylation is a base modification that is often used by genomes to store information that is stably inherited through mitotic cell divisions. Most cytosine DNA methylation is stable throughout different cell types or by exposure to different environmental conditions in plant genomes. Here, we profile the epigenomes of ~100 Glycine max lines to explore the extent of natural epigenomic variation. We also use these data to determine the extent to which DNA methylation variants are linked to genetic variations.
Project description:Soybean near-isogenic lines (NILs) differing in iron deficiency chlorosis (IDC) tolerance were genotyped to determine differential genetic introgressions from the donor line T203 into the Clark background. The CGH comparison reveals T203 loci that are differentially introgressed between the IsoClark sub-lines. Comparison of IsoClark soybean NILs to the recurrent parent Clark; the reported values show the log2 ratio of the normalized IsoClark hybridization signals (Cy3) over the normalized Clark hybridization signal (Cy5)
