the genus hyoscyamus belongs to the tribe hyoscyameae miers of solanaceae family. variation in protein bands elaborates the relationship among the collections from various geographical regions. in this study the seed storage protein diversity of 19 accessions of hyoscyamus (h. niger, h. reticulatus and  h. pusillus) from west azerbaijan (iran) was investigated according to the sodium dodecyl su...

Soybean flours stored for 20 years at -20 degrees C retained protein polypeptide profile integrity. Proteins in stored soybean flours retained their immunoreactivity. Long-term frozen storage of seed flours at -20 degrees C did not adversely affect seed protein in vitro pepsin digestibility.

Soybean breeding programs have developed genetic lines with relatively low seed protein, which could negatively impact early seedling growth in low fertility conditions commonly encountered in the field. In these experiments, seed protein mobilization and its regulation in situ in soybean lines with different seed protein levels was investigated. The results showed that rates of nitrogen (N) re...

an experiment was conducted to study wheat grain protein increasing through foliar application of nitrogen afterflowering. the rcbd design was analysed with three replications and four n-treatments as foliar application as(n0=0, n1=4kg.ha-1 urea, n2=8kg.ha-1 urea, n3=4kg.ha-1 ammonium sulfate). results showed that seed proteincontent increased significantly by foliar application of nitrogen. da...

Seed vigor is a complex property that determines the seed's potential for rapid uniform emergence and subsequent growth. However, the mechanism for change in seed vigor is poorly understood. The seeds of poplar (Populus × Canadensis Moench), which are short-lived, were stored at 30 °C and 75 ± 5% relative humidity for different periods of time (0-90 days) to obtain different vigor seeds (from 9...

abstract phosphoenolpyruvate carboxykinase, encoded by the pepck gene, plays an important role in gluconeogenesis. it also seems to be important in metabolism of nitrogenous compounds in developing seeds of legumes, including amides and ureides which are then transformed into amino acids, necessary for the synthesis of storage proteins. in this research, pepck gene expression in mrna level, in ...

Two primary biochemical reactions in seed ageing (lipid peroxidation and non-enzymatic protein glycosylation with reducing sugars) have been studied under different seed water contents and storage temperatures, and the role of the glassy state in retarding biochemical deterioration examined. The viability loss of Vigna radiata seeds during storage is associated with Maillard reactions; however,...

Seed dormancy controls the start of a plant's life cycle by preventing germination of a viable seed in an unfavorable season. Freshly harvested seeds usually show a high level of dormancy, which is gradually released during dry storage (after-ripening). Abscisic acid (ABA) has been identified as an essential factor for the induction of dormancy, whereas gibberellins (GAs) are required for germi...
