Cellular Localization of Wheat High Molecular Weight Glutenin Subunits in Transgenic Rice Grain
Rice (Oryza sativa L.) is a primary global food cereal. However, when compared to wheat, rice has poor food processing qualities. Dough that is made from rice flour has low viscoelasticity because rice seed lacks storage proteins that are comparable to gluten protein from wheat. Thus, current research efforts aim to improve rice flour processing qualities through the transgenic expression of vi...
متن کاملConserved cis-regulatory modules in promoters of genes encoding wheat high-molecular-weight glutenin subunits
The concentration and composition of the gliadin and glutenin seed storage proteins (SSPs) in wheat flour are the most important determinants of its end-use value. In cereals, the synthesis of SSPs is predominantly regulated at the transcriptional level by a complex network involving at least five cis-elements in gene promoters. The high-molecular-weight glutenin subunits (HMW-GS) are encoded b...
متن کاملThe glutenin macropolymer of wheat ̄our doughs: structure±function perspectives
Gluten is the main functional component of wheat, and is the main source of the viscoelastic properties in a dough. Dough properties are primarily governed by the structure of gluten, and interactions within the protein complex. While starch and water are the main components of doughs, the physical properties of a dough arise from interactions between gluten proteins, particularly the disul®de-...
متن کاملVariant high-molecular-weight glutenin subunits arising from biolistic transformation of wheat
Genetic transformation via the biolistic method has been used to introduce genes encoding natural and novel high-molecular-weight glutenin subunits (HMW-GS) into wheat. The appearance of new seed proteins of sizes not predicted by the transgene coding sequences was noted in some experiments. In this report, the identities of thirteen of these novel proteins were determined by tandem mass spectr...
متن کاملThe Importance of High-molecular-weight Glutenin Subunits for Wheat Quality Evaluation
High-molecular-weight glutenin subunits (HMW-GS) composition was analyzed by sodium-dodecyl-sulfatpolyacrilamid-gel electrophoresis (SDS-PAGE), while the quantitative determination of total HMW-GS was obtained by reversed phasehigh performance liquid chromatography (RP-HPLC). Considering HMW-GS composition, the most frequent subunits at Glu-A1 locus were N, at Glu-B1 locus 7+9 and at Glu-D1 loc...
