There is a renewal of interest in endosperm development. Recent studies are leading the way to a better understanding of fundamental processes such as cell cycle control and the mechanisms of imprinting. A more global view of interactions between the endosperm and the embryo is emerging and will initiate an integrated approach to the study of seed ...

Development: Turning on endosperm in seeds
Nature Plants, 2015Causal signals for seed initiation have been sought ever since double fertilization was discovered in 1898. New research reveals that auxin is an early driver of endosperm proliferation in Arabidopsis central cells, with or without fertilization.

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.

Genetics, 2022
AbstractSeed size is related to plant evolution and crop yield and is affected by genetic mutations, imprinting, and genome dosage. Imprinting is a widespread epigenetic phenomenon in mammals and flowering plants. ETHYLENE INSENSITIVE2 (EIN2) encodes a membrane protein that links the ethylene perception to transcriptional regulation.

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

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.

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).
