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. To test this hypothesis, we examined the protein profiles of developing and germinating seeds from Arabidopsis plants containing transposon-insertional knockout mutations in the genes that encode the two ...

Until recently, storage protein research has been largely restricted to the seed-specific reserve proteins, which provide nutrients to seedlings during their early growth. Their abundance, and the potential for improving seed nutritional quality, were early incentives to investigate seed storage proteins, and they continue to be intensively studied as a plant model for tissue-specific and devel...

canola is one of the most important crops in the world and ranked as the third most important oil seed crop. adverse environmental storage conditions including high temperature and relative humidity could affect canola seed quality. the aim of this study was to evaluate the seed quality of canola seed under various seed moisture content, temperature and storage time using okapi cultivar. also, ...

Seed development culminates in programmed cell death (PCD) and hardening of organs enclosing the embryo (e.g., pericarp, seed coat) providing essentially a physical shield for protection during storage in the soil. We examined the proposal that dead organs enclosing embryos are unique entities that store and release upon hydration active proteins that might increase seed persistence in soil, ge...

Loss of aquatic plant species has occurred in coastal and freshwater habitats throughout the world. In particular, population and habit loss of the submerged aquatic species, Vallisneria americana Michx., have made it a potential restoration candidate. For successful restoration, reliable seed sources are vital for producing plants or for direct seeding. Seed survival and their ability to retai...

We have measured the numbers of genes coding for the three seed storage proteins, vicilin, convicilin and legumin, in a number of Pisum genotypes of variant protein composition. No difference in gene number existed among P. sativum genotypes for any of the proteins. There were differences in the number of genes coding for individual proteins with approximately 11 genes (per haploid genome) for ...

A field experiment was performed in order to evaluate the effects of irrigation and application of K fertilizer on seed storage proteins  in chickpea, ILC-482 cultivar. Experiment was performed in factorial using randomized complete block design with three replications. In this experiment, two factor consist of irrigation in three levels (I1= non irrigation and I2= irrigation in flowering stage...

The accumulation of storage compounds is an important aspect of cereal seed metabolism. Due to the agronomical importance of the storage reserves of starch, protein, and oil, the understanding of storage metabolism is of scientific interest, with practical applications in agronomy and plant breeding. To get insight into storage patterning in developing cereal seed in response to environmental a...
