Plant seed cells amass storage proteins that are synthesized on the endoplasmic reticulumn (ER) and then transported to protein storage vacuoles (PSVs). Many dicotyledonous seeds contain 11S globulin (11S) as a major storage protein. We investigated the accumulation behaviors of pea and pumpkin 11S during seed maturation and compared them with soybean 11S biogenesis (Mori et al., 2004). The acc...
Both polysomes and polysomal RNA, isolated from cotyledons of ripening pea (Pisum sativum) seeds and supplemented respectively with wheat germ S-100 and S-30 fractions, were used to program the cell-free synthesis of polypeptides. The relationship of these polypeptide products to seed storage proteins has been investigated. When fractionated on sucrose density gradients the translation products...
A competitive enzyme-linked immunosorbent assay (ELISA) was developed to quantify endogenous acetaldehyde-protein adducts (APAs) produced in plant seeds at low acetaldehyde concentrations without exogenous reducing agents. The key point of this technique is the use of a gelatin-acetaldehyde adduct, which is synthesized under 1 mM acetaldehyde and 10 mM NaCNBH3, to pre-coat plate wells to obtain...
The impact of chemical desiccation on yield showed contrasting results depending on seedmoisture content at the time of application. Its effects on seed deterioration are still unknownand could be modified by seed composition. Objectives were to evaluate the impact of chemicaldesiccation on: i) hybrid sunflower seed yield and composition at harvest time, ii) seeddeterioration during long-term s...
Background Kiwi fruit is a common food allergen and severe allergic reactions are observed. The current diagnostic accuracy is poor with a reported diagnostic sensitivity of 65% in a large European cohort. Recently, two new kiwi allergens were registered, both being storage proteins and both isolated from kiwi seeds. Storage proteins are often linked to severe clinical reactions in other food a...
Background and Objectives: Encapsulation is a process; by which, a susceptible compound is surrounded with a membrane or matrix that is able to release its contents at a controlled speed under certain conditions. In recent years, popularity of adding bioactive compounds to food products has increased. These compounds are usually sensitive to environmental, processing and/or gastrointestinal con...
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...
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...
Secale montanum is one of the important perennial grasses growingnaturally in arid to semiarid pastures and rangelands, with a typical Mediterraneanclimate, in northern and western Iran at altitudes of 800-2900 m. In this paper, seedstorage protein profiles of nine wild populations of S. montanum from differentregions of Iran and their phenotypically superior progenies as well as a multi-origin...
