Hourglass cells (HGC) are prominent cells in the legume seed coat. Miller et al. (pp. 235–242) document HGC development in soybean, Glycine max, and relate structural changes to expression of an HGC-specific soybean peroxidase (SBP). SBP protein and activity are detectable in HGCs before differentiation is complete; furthermore, activity appears vacuolar, as predicted. These results provide a basis for biotechnology aimed at protein targeting to components of the HGC endomembrane systems.
Can a better understanding of proteomic responses to low phosphorus conditions be harnessed to improve future soybean varieties?
A new framework aids in predicting gene regulatory networks associated with soybean nodule formation.
Reactive oxygen species (ROS), such as hydrogen peroxide (H2O2), can promote seed germination in a number of species but their role in soybean has not been fully determined. Ishibashi et al. use the anti-oxidant N...
