Microtubule Components of the Plant Cell Cytoskeleton.
Like the skeleton of any vertebrate animal, the cytoskeleton plays a major role in detennining the three-dimensional form of a cell. However, in plants the cytoskeleton is probably more analogous to a scaffold, being directly involved in the establishment of cell morphology and less involved in the maintenance of cell shape once the relatively rigid cell walls are in place. The term "skeleton" ...

این مطالعه در سال 1386-87 در آزمایشگاه و مزرعه پژوهشی دانشگاه صنعتی اصفهان به منظور تعیین مناسب ترین تیمار بذری و ارزیابی اثر پرایمینگ بر روی سه رقم گلرنگ تحت سه رژیم آبیاری انجام گرفت. برخی از مطالعات اثرات سودمند پرایمینگ بذر را بر روی گیاهان مختلف بررسی کرده اند اما در حال حاضر اطلاعات کمی در مورد خصوصیات مربوط به جوانه زنی، مراحل نموی، عملکرد و خصوصیات کمی و کیفی بذور تیمار شده ژنوتیپ های م...
Improved robustness of time-frequency principal components (TFPC) by synergy of methods in different domains
Our previously proposed integration of time-frequency principal components (TFPC) features and histogram equalization (HEQ) has improved the performance of TFPC features under mismatched conditions. To further enhance the robustness of TFPC features, we herein propose to (a) replace HEQ with another feature normalization technique, progressive histogram equalization (PHEQ), (b) combine the two-...
متن کاملPreparation and properties of a complex from rat liver of polyribosomes with components of the cytoskeleton.
Gel filtration with 1% agarose (Bio-Gel A-150m) separates polyribosomes bound to microsomal membranes from 'free' polyribosomes when these fractions are prepared by standard centrifugal techniques. However, when polyribosomes contained in an unfractionated postmitochondrial supernatant are run on an identical column, over 90% of the total polyribosomes are present as aggregates, designated 'mem...
متن کاملDefinition of individual components within the cytoskeleton of Trypanosoma brucei by a library of monoclonal antibodies.
The detergent-insoluble T. brucei cytoskeleton consists of several morphologically distinct regions and organelles, many of which are detectable only by electron microscopy. We have produced a set of monoclonal antibodies that define each structural component of this highly ordered cytoskeleton. The monoclonal antibodies were selected by cloning of hybridomas produced from mice injected with co...
