Aquaporins Constitute a Large and Highly Divergent Protein Family in Maize
Aquaporins (AQPs) are an ancient family of channel proteins that transport water and neutral solutes through a pore and are found in all eukaryotes and most prokaryotes. A comparison of the aminoExpand

Plasma membrane intrinsic proteins from maize cluster in two sequence subgroups with differential aquaporin activity.
The transport of water through membranes is regulated in part by aquaporins or water channel proteins. These proteins are members of the larger family of major intrinsic proteins (MIPs). PlantExpand

Genomics Analysis of Genes Expressed in Maize Endosperm Identifies Novel Seed Proteins and Clarifies Patterns of Zein Gene Expression
We analyzed cDNA libraries from developing endosperm of the B73 maize inbred line to evaluate the expression of storage protein genes. This study showed that zeins are by far the most highlyExpand

The Proteolytic Processing of Seed Storage Proteins in Arabidopsis Embryo Cells Starts in the Multivesicular Bodies[W]
We have investigated the transport of storage proteins, their processing proteases, and the Vacuolar Sorting Receptor-1/Epidermal Growth Factor Receptor–Like Protein1 (VSR-1/ATELP1) receptor duringExpand

The defective kernel 1 (dek1) gene required for aleurone cell development in the endosperm of maize grains encodes a membrane protein of the calpain gene superfamily
Endosperm of cereal grains is one of the most important renewable resources for food, feed, and industrial raw material. It consists of four triploid cell types, i.e., aleurone, starchy endosperm,Expand

Maize Opaque Endosperm Mutations Create Extensive Changes in Patterns of Gene Expression Online version contains Web-only data. Article, publication date, and citation information can be found at
Maize starchy endosperm mutants have kernel phenotypes that include a brittle texture, susceptibility to insect pests, and inferior functional characteristics of products made from their flour. AtExpand

Phylogenetic Analyses Identify 10 Classes of the Protein Disulfide Isomerase Family in Plants, Including Single-Domain Protein Disulfide Isomerase-Related Proteins1[w]
Protein disulfide isomerases (PDIs) are molecular chaperones that contain thioredoxin (TRX) domains and aid in the formation of proper disulfide bonds during protein folding. To identify plantExpand

Storage Protein Accumulation in the Absence of the Vacuolar Processing Enzyme Family of Cysteine Proteases Online version contains Web-only data. Article, publication date, and citation information
The role(s) of specific proteases in seed protein processing is only vaguely understood; indeed, the overall role of processing in stable protein deposition has been the subject of more speculationExpand

Redundant Proteolytic Mechanisms Process Seed Storage Proteins in the Absence of Seed-Type Members of the Vacuolar Processing Enzyme Family of Cysteine Proteases
Seed-type vacuolar processing enzyme (VPE) activity is predicted to be essential for post-translational proteolysis of seed storage proteins in the protein storage vacuole of developing seeds. ToExpand

A Defective Signal Peptide in a 19-kD α-Zein Protein Causes the Unfolded Protein Response and an Opaque Endosperm Phenotype in the Maize De*-B30 Mutant1
Defective endosperm* (De*)-B30 is a dominant maize (Zea mays) mutation that depresses zein synthesis in the developing endosperm. The mutant kernels have an opaque, starchy phenotype, malformed zeinExpand
