this experiment was conducted in safi abad agricultural research center of dezful in order to study the effect of seed deterioration and plant density on germination, seedling establishment, yield and yield components of hull-less barley with in 2011- 2012. treatments included three levels of seed deterioration: (control, 72 and 96 hours) and five plant densities (100, 150, 200, 250 and 300 pla...

The tonoplast intrinsic proteins TIP3;1 and TIP3;2 are specifically expressed during seed maturation and localized to the seed protein storage vacuole membrane. However, the function and physiological roles of TIP3s are still largely unknown. The seed performance of TIP3 knockdown mutants was analysed using the controlled deterioration test. The tip3;1/tip3;2 double mutant was affected in seed ...

The present study aimed to compare the nutritional and biochemical composition of Indian legume seed (white and black seeds of Velvet beans) flour used by tribals of South India. The crude protein content was higher in white seed compared to black seed; but the nutritive values of black seeds were better compared to the white seeds. The mineral constituents of both seed flour was found to be hi...

to evaluate the effect of drought stress, biofertilizer and chemical phosphorus fertilizer on yield and seed protein percentage of two lentil cultivars, an experiment was conducted in split factorial based on crbd design with 4 replications in research farm of university of tehran (karaj-iran) during 2009-10. the main factor including three irrigation levels (irrigation after 70, 90 and 130 mm ...

Seed corn (Zea mays L.) producers in the Midwest region of the United States are affected by an early fall frost approximately every five years. The negative effects of frost on seed quality vary according to genotype and thus possibly seed composition. Our objective was to determine the effect of seed composition (oil and protein) and seed maturity on seed viability and vigor of artificially f...

Target recognition in RNA silencing is governed by the "seed sequence" of a guide RNA strand associated with the PIWI/MID domain of an Argonaute protein in RISC. Using a reconstituted in vitro target recognition system, we show that a model PIWI/MID domain protein confers position-dependent tightening and loosening of guide-strand-target interactions. Over the seed sequence, the interaction aff...

To better understand seed germination, a complex developmental process, we developed a proteome analysis of the model plant Arabidopsis for which complete genome sequence is now available. Among about 1,300 total seed proteins resolved in two-dimensional gels, changes in the abundance (up- and down-regulation) of 74 proteins were observed during germination sensu stricto (i.e. prior to radicle ...

BACKGROUND Ricinus communis (Euphorbiaceae) has previously been reported to possess analgesic, antihistamine, antioxidant and anti-inflammatory activities. This study was designed for isolation, characterization and evaluation of antibacterial and anti-proliferative activities of R. communis seed protein. METHODS The concentration and molecular weight of R. communis seed protein were estimate...

The Seed Proteome Web Portal (SPWP; http://www.seed-proteome.com/) gives access to information both on quantitative seed proteomic data and on seed-related protocols. Firstly, the SPWP provides access to the 475 different Arabidopsis seed proteins annotated from two dimensional electrophoresis (2DE) maps. Quantitative data are available for each protein according to their accumulation profile d...
