From the Pangenome search page you can compare your sequence or sequences of interest to a number of other De Novo sequenced soybean cultivars (G. max or G. soja). This type of analysis will allow users the ability to see how sequences evolved (were eliminated or were retained) in the various soybean cultivars.

GSE42550 "Transcription factors and glyoxylate cycle genes prominent in the transition of soybean cotyledons to the first functional leaves of the seedling" is now browsable on the SoyBase Genome Viewer. This experiment profiles gene expression in cotyledons at 7 developmental stages. The experiment can be browsed HERE under the label of "Expression profiling Williams cotyledon development".
