Phylogenetic relationship of a new class of LMW-GS genes in the M genome of Aegilops comosa.

A new class of low molecular weight glutenin subunit (LMW-GS) genes was isolated and characterized from Aegilops comosa (2n = 2x = 14, MM). Although their DNA structure displayed high similarity to LMW-i type genes, there are some key differences. The deduced amino acid sequences of their mature proteins showed that the first amino acid residue of each gene was leucine and therefore they were designated as LMW-l type subunits.

Gene networks in the synthesis and deposition of protein polymers during grain development of wheat.

As the amino acid storing organelle, the protein bodies provide nutrients for embryo development, seed germination and early seedling growth through storage proteolysis in cereal plants, such as wheat and rice. In protein bodies, the monomeric and polymeric prolamins, i.e.
