INTRODUCTION Sunflower (Helianthus annuus L., Asteraceae), currently cultivated for its seeds, is the world’s fourth largest oil-seed crop. World seed production was 25.2 million tonnes (t) during 1995/1996 from approximately 50 million ha of cultivated land. In the US, during 1999, sunflower seed production was 1,971,205 t from 1,438,000 ha, according to the National Agricultural Statistics Se...

The increasing use of soybean (Glycine max) products in processed foods poses a potential threat to soybean-sensitive food-allergic individuals. In vitro assays on soybean seed proteins with sera from soybean-sensitive individuals have immunoglobulin E reactivity to abundant storage proteins and a few less-abundant seed proteins. One of these low abundance proteins, Gly m Bd 30 K, also referred...

this experiment was conducted to evaluate the seed storage protein of seven different species of papaver in ardabil province, iran by sds-page method. by scoring banding patterns data, a total of 20 loci were identified in the species. maximum number of protein band (17 bands) was belonged to p. bracteatum and p. rhoease. minimum number of protein band (13 bands) was related to the species of p...

Quinoa (Chenopodium quinoa Willd) is an ancient Andean seed-producing crop well known for its exceptional nutritional properties and resistance to adverse environmental conditions, such as salinity and drought. Seed storage proteins, amino acid composition, and bioactive compounds play a crucial role in determining the nutritional value of quinoa. Seeds harvested from three Chilean landraces of...

Extraction of soybean seed proteins for two-dimensional polyacrylamide gel electrophoresis (2D-PAGE) and mass spectrometry analysis is challenging and inconsistent. In this study, we compared four different protein extraction/solubilization methods-urea, thiourea/urea, phenol, and a modified trichloroacetic acid (TCA)/acetone-to determine their efficacy in separating soybean seed proteins by 2D...

This study aims to identify the types of proteins in malted and dry Bambara groundnut seeds and through a comparative analysis, identify similarities and their known uses. Dry viable bambara seed was stored for five days to malt. The proteins in the dry and malted seed were subsequently extracted in potassium phosphate buffer pH 7.0 and precipitated with saturated ammonium sulphate. MudPit (mul...

Objective: Ageing of the stored seed is a natural phenomenon and the seeds tend to lose viability even under ideal storage conditions. Accelerated ageing has been recognized as a good predictor of the storability of seed lots. Aged seeds show decreased vigor and produce weak seedlings that are unable to survive once reintroduced into a habitat. The characteristics of the chemical composition of...

seed protein profiles of 47 accessions belonging to eleven species and four tribes of grain legumes were studied, by extracting the total proteins from ten single seeds in each accession and performing sds-polyacrylamide gel electrophoresis. all eleven species were clearly recognizable from their protein banding patterns, but only phaseolus vulgaris expressed high intraspecific variations, ...
