Plastids first come from what is called a proplastid. A proplastid is an organelle that has not matured into its final function. A proplastid can divide and become another proplastid, or it can mature into a specific functioning plastid. There are various types of plastids into which a pro...
Etioplast ultrastructure is dominated by the prolamellar body (PLB), a large, crystalline lattice of membranes (Figure 2(b);Gunning, 2001). While the exact function of the PLB remains obscure, it probably represents a ‘holding pattern’ for the large amount of membrane and protein that will...
we first examined zein protein synthesis. We found that A619 accumulates zein proteins at a level that is apparently lower than in W64A (Supplementary Fig.6a). Therefore, it was possible that insufficient accumulation of zein proteins resulted in a reduction of PB number and size5, which in t...
Starch granule initiation is poorly understood at the molecular level. The glucosyltransferase, STARCH SYNTHASE 4 (SS4), plays a central role in granule initiation in Arabidopsis leaves, but its function in cereal endosperms is unknown. We investigated the role of SS4 in wheat, which has a dis...
