Abstract: Analysis of the expression of genes encoding the beta-conglycinin seed storage proteins in soybean has been used to extend our understanding of developmental gene expression in plants. The alpha, alpha', and beta subunits of beta-conglycinin are encoded by a multigene family which is organ-specific in its expression. In this study we report the differentially programmed accumulation of the alpha, alpha', and beta subunits of beta-conglycinin. Multiple isomeric forms of each subunit are present in the dry seed, but the timing of their accumulation is unique for each subunit. The previously reported variation in amount of alpha' and alpha subunits in axis and cotyledons is also reflected in the amount of subunit specific mRNA which is present in each tissue. The beta subunit, previously undetected in soybean axes, is found to be synthesized but rapidly degraded. These differences in beta-conglycinin protein accumulation may be reflected by the morphological differences observed in protein bodies between these two tissues.
