Compressive Strength of Wheat Endosperm: Analysis of Endosperm Bricks
Cereal Chemistry, 2008ABSTRACTThe material properties of wheat grain endosperm are central to its processing and end‐use quality. The preparation of geometrically‐defined endosperm specimens free of bran, germ, and pigment strand can facilitate the objective study of endosperm material properties.

The structure of the lettuce endosperm
Planta, 1974The two-cell-layered endosperm of lettuce (Lactuca sativa L.) is characterized by thick cell walls and dense cytoplasm. The periodic-acid-Schiff's(PAS)-positive cell wall forms numerous peg-like projections which extend into the cytoplasm. The dense cytoplasm contains organelles of protein and lipid storage.

1. Statistical analysis of available data on the types of endosperm and of vessel perforation in dicotyledonous taxa indicates that (a) Nuclear-type endosperm is positively associated with porous perforation and that (b) Cellular-type endosperm is negatively associated with such perforation. 2. As it has been well established that porous perforation of

Maize Endosperm Proteins That Contribute to Endosperm Lysine Content
Cereal Chemistry, 1999ABSTRACTNonzein proteins were analyzed using SDS‐PAGE to study their relationship to lysine level in mature endosperm of three isogenic lines and 29 inbred lines. The majority of nonzein proteins are glutelins that contain a relatively high lysine content.

IN Trillium grandiflorum and other species of the same genus, cold treatment reveals differences between homologous chromosomes with regard to number and/or length of heterochromatic segments1. In our experiments, differences have been found in the B-, C- and E-chromosomes (Figs. 1, 2A).

IN preparing an account of the life-history of Acacia Baileyana, I have found strong evidence of polyspermy in connexion with endosperm formation. The polar nuclei, unfused before fertilisation, have one large nucleolus each. The sperm, which on first contact with the polar nuclei has 13 chromosomes present1 (presumably telophase) (Fig.

Starch synthesis in the cereal endosperm
Current Opinion in Plant Biology, 2003The pathway of starch synthesis in the cereal endosperm is unique, and requires enzyme isoforms that are not present in other cereal tissues or non-cereal plants. Recent information on the functions of individual enzyme isoforms has provided insight into how the linear chains and branch linkages in cereal starch are synthesized and distributed. Genetic

Developmental biology of the cereal endosperm
Trends in Plant Science, 1999The recent application of immunohistochemistry and molecular techniques has revealed that endosperm development depends on a genetic program that combines an ancient process for cellularization (similar to that seen in late Paleozoic seed ferns) with a mechanism for specifying asymmetric cell fates that has parallels to signaling processes in mammals ...

Starch biosynthesis in cereal endosperm
Plant Physiology and Biochemistry, 2010Stored starch generally consists of two d-glucose homopolymers, the linear polymer amylose and a highly branched glucan amylopectin that connects linear chains. Amylopectin structurally contributes to the crystalline organization of the starch granule in cereals.
