Wheat (Triticum aestivum L.) is one of the oldest cultivated crops and the second most important food crop in the world. Seed germination is the key developmental process in plant growth and development, and poor germination directly affects plant growth and subsequent grain yield. In this study, we performed the first dynamic proteome analysis of wheat seed germination using a two-dimensional ...
Storage proteins are deposited into protein storage vacuoles (PSVs) during plant seed development and maturation and stably accumulate to high levels; subsequently, during germination the storage proteins are rapidly degraded to provide nutrients for use by the embryo. Here, we show that a PSV has within it a membrane-bound compartment containing crystals of phytic acid and proteins that are ch...
The expression of the alpha and alpha' subunits of beta-conglycinin was suppressed by sequence-mediated gene silencing in transgenic soybean seed. The resulting seeds had similar total oil and protein content and ratio compared with the parent line. The decrease in beta-conglycinin protein was apparently compensated by an increased accumulation of glycinin. In addition, proglycinin, the precurs...
Flax (Linum usitatissimum L.) seeds are an important source of food and feed due to the presence of various health promoting compounds, making it a nutritionally and economically important plant. An in-depth analysis of the proteome of developing flax seed is expected to provide significant information with respect to the regulation and accumulation of such storage compounds. Therefore, a prote...
Background IgE sensitization to storage proteins from nuts and seed is often related to severe allergic symptoms. There is a risk of immunological IgE cross-reactivity between storage proteins from different species. The potential clinical implication of such cross-reactivity is that allergens other than the known sensitizer can cause allergic symptoms. Previous studies have suggested that kiwi...
The composition of seed storage proteins (SSPs) in olive endosperm and cotyledon has been analyzed. Precursor forms of these proteins are made up of individual proteins, which have been purified to homogeneity and further named p1-p5 (20.5, 21.5, 25.5, 27.5, and 30 kDa, respectively). N-terminal sequences of p1 and p2 proteins displayed relevant homology to the basic subunit of the 11S family o...
پروتئین های ذخیره ای بذر در 21 جمعیت 17 گونه و واریته bromus ایران بررسی شد. بطور کلی تعداد 83 باند پروتئینی مشاهده شد. گونه های مطالعه شده در تعداد و شدت باند تفاوت داشتند که بیانگر تفاوت های ژنتیکی آنهاست. تعدادی باند منحصر به فرد در اکثر گونه ها وجود داشتند که نشان دهنده وجود ژن های خاص در این گونه هااست که در طی گونه زایی بدست آمده اند. از این باندهای منحصر به فرد می توان در شناسایی و تفکیک...
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...
