Summarized expression data for soybean bHLHs. 281 soybean bHLHs were found to be expressed. Root and nodule expression classes were combined as all, but 11 of the 150 nodule-expressed bHLHs were found to also be represented in the root class. Three of the total expressed bHLHs were detected only in pod wall tissues (see Additional File 1).
