A model for IAB deposition. a A schematic of IAB deposition from ovule to seed. Purple, nucellus; turquoise, female gametophyte; brown, endothelium; blue, endosperm; green, embryo. The yellow line represents the IAB deposited during ovule development, whereas the red line marks the newly deposited IAB after fertilization
b Genetic pathway regulating IAB deposition. Black and red arrows indicate functional and molecular relationships, respectively. Dashed arrows indicate unknown regulatory mechanisms.
