TL;DR: This review will focus first on the present understanding of the structures of amylose and amylopectin and their organization within the granule, and then on the biosynthetic mechanisms explaining the biogenesis of starch in plants.

TL;DR: In this paper, the organization of various starch samples varying in molecular structure, organization and moisture content was studied by ATR-FTIR spectroscopy, which showed that the helix organization at a short order range was weakly moisture dependant below T g, whereas the signal became increasingly water dependant with the crystalline/amorphous ratio above T g.

TL;DR: In this article, the authors characterized Arabidopsis mutants defective for the synthesis of the soluble starch synthase IV (SSIV) type of elongation enzyme and found that the number of granules per plastid has dramatically decreased leading to a large increase in their size, suggesting a specific function of this enzyme class in the control of granule numbers.

TL;DR: It is shown that SSIV is necessary and sufficient to establish the correct number of starch granules observed in wild-type chloroplasts and that other starch synthases cannot support starch synthesis despite remaining enzymatically active.

TL;DR: Testing the interdependence of the maize enzymes starch synthase IIa, SSIII, starch branching enzyme IIb, and SBEIIa for assembly into multisubunit complexes found that these complexes may function in global regulation of carbon partitioning between metabolic pathways in developing seeds.
