Do Cupins Have a Function Beyond Being Seed Storage Proteins?
Plants continue to flourish around the site of the Chernobyl Nuclear Power Plant disaster. The ability of plants to transcend the radio-contaminated environment was not anticipated and is not well understood. The aim of this study was to evaluate the proteome of flax (Linum usitatissimum L.) during seed filling by plants grown for a third generation near Chernobyl. For this purpose, seeds were ...
متن کاملA role for seed storage proteins in Arabidopsis seed longevity
Proteomics approaches have been a useful tool for determining the biological roles and functions of individual proteins and identifying the molecular mechanisms that govern seed germination, vigour and viability in response to ageing. In this work the dry seed proteome of four Arabidopsis thaliana genotypes, that carry introgression fragments at the position of seed longevity quantitative trait...
متن کاملSeed storage proteins: structures and biosynthesis.
The plant seed is not only an organ of propagation and dispersal but also the major plant tissue harvested by humankind. The amount of protein present in seeds varies from -10% (in cereals) to -40% (in certain legumes and oilseeds) of the dry weight, forming a major source of dietary protein. Although the vast majority of the individual proteins present in mature seeds have either metabolic or ...
متن کاملPhylogeny, function, and evolution of the cupins, a structurally conserved, functionally diverse superfamily of proteins.
The cupin superfamily is a group of functionally diverse proteins that are found in all three kingdoms of life, Archaea, Eubacteria, and Eukaryota. These proteins have a characteristic signature domain comprising two histidine- containing motifs separated by an intermotif region of variable length. This domain consists of six beta strands within a conserved beta barrel structure. Most cupins, s...
متن کاملCharacterization of seed storage proteins in Populus and their homology with Populus vegetative storage proteins.
We investigated the synthesis and accumulation of vegetative storage proteins (VSPs) in poplar plantlets and the homology between poplar seed storage proteins (SSPs) and VSPs. One-dimensional SDS polyacrylamide gel electrophoresis confirmed that both seed and vegetative storage proteins contained two predominant polypeptides of MW 32 and 36 kDa, but the subunit composition of the polypeptides d...
