Source-Sink Relationships and Its Effect on Plant Productivity: Manipulation of Primary Carbon and Starch Metabolism
The rate of photo-assimilation in source organs (source strength) and the rate of conversion of this photo-assimilate into end products in sink organs (sink strength) are the two key metabolic processes that d...

Characterization of RNA binding protein RBP-P reveals a possible role in rice glutelin gene expression and RNA localization
RNA binding proteins (RBPs) play an important role in mRNA metabolism including synthesis, maturation, transport, localization, and stability. In develo** rice seeds, RNAs that code for the major storage pro...

In vitro cultures and regeneration of Bienertia sinuspersici (Chenopodiaceae) under increasing concentrations of sodium chloride and carbon dioxide
To study the developmental transition of chloroplasts from C3 to C4 photosynthesis in the terrestrial single-cell C4 species Bienertia sinuspersici, a regeneration protocol was developed. Stem explant material de...

Isolation and identification of cytoskeleton-associated prolamine mRNA binding proteins from develo** rice seeds
The messenger RNA of the rice seed storage protein prolamine is targeted to the endoplasmic reticulum (ER) membranes surrounding prolamine protein bodies via a mechanism, which is dependent upon both RNA sorti...

Structural changes in the vacuole and cytoskeleton are key to development of the two cytoplasmic domains supporting single-cell C4 photosynthesis in Bienertia sinuspersici
Bienertia sinuspersici Akhani has an unusual mechanism of C4 photosynthesis which occurs within individual chlorenchyma cells. To perform C4, the mature cells have two cytoplasmic compartments consisting of a cen...

Identification of the ADP-glucose pyrophosphorylase isoforms essential for starch synthesis in the leaf and seed endosperm of rice (Oryza sativa L.)
ADP-glucose pyrophosphorylase (AGP) catalyzes the first committed step of starch biosynthesis in higher plants. To identify AGP isoforms essential for this biosynthetic process in sink and source tissues of ri...

Targeting of RNAs to ER Subdomains and its Relationship to Protein Localization
The targeting of proteins to specific subcellular regions is directed by a variety of signalelements. Many of these signals consist of amino acid residues (peptide sorting signals) arranged contiguouslyor in a...

Relative turnover numbers of maize endosperm and potato tuber ADP-glucose pyrophosphorylases in the absence and presence of 3-phosphoglyceric acid
Adenosine diphosphate glucose pyrophosphorylase (AGPase; EC 2.7.7.27) synthesizes the starch precursor, ADP-glucose. It is a rate-limiting enzyme in starch biosynthesis and its activation by 3-phosphoglyceric ...

Generation, characterization, and heterologous expression of wild-type and up-regulated forms of Arabidopsis thaliana leaf ADP-glucose pyrophosphorylase
ADP-glucose pyrophosphorylase (AGPase), a key enzyme in starch biosynthesis of higher plants, consists of a pair of regulatory large (LS) and catalytically small (SS) subunits. In plants, these subunits are c...

Identification of a cytoskeleton-associated 120 kDa RNA-binding protein in develo** rice seeds
During rice seed development, prolamine RNAs are localized to the surface of the prolamine storage protein bodies (PBs), organelles bounded by the endoplasmic reticulum (ER). The exact mechanism by which prola...

Messenger RNA targeting of rice seed storage proteins to specific ER subdomains
Rice seeds, a rich reserve of starch and protein, are a major food source in many countries. Unlike the seeds of other plants, which typically accumulate one major type of storage protein, rice seeds use two m...

Rice Glutelins
Despite being the major food for many people in Asia, Africa and South America, rice contains the lowest protein content (ca. 5%) of the major cereals. Moreover, a considerable percentage of this protein is no...

The Prolamins of Rice
The storage proteins of rice seed differ from those of most cereals, other than oats, in that globulin rather than prolamin is the most abundant storage protein (Muench and Okita, 1997a). Although the prolamin...
