Dryland winter wheat (Triticum aestivum L.) production plays an extremely important role in the southeast of Loess Plateau. Planting patterns have great influence on improving soil water storage and yield, should be matched with different seeding rates. In order to assess effect sowing methods drought resistance stable yield dryland wheat, a field experiment was conducted Wenxi County Wheat Exp...

Formation of the first cleavage furrow in the telolecithal egg of Loligo was studied with the electron microscope . Before the actual furrow forms, a dense filamentous band develops below the plasma membrane from membrane-bounded dense bodies which appear to be Golgi-derived . The egg surface is thrown into a number of longitudinal folds which parallel the furrow and eventually become incorpora...

Coordinated membrane and cytoskeletal remodeling activities are required for membrane extension in processes such as cytokinesis and syncytial nuclear division cycles in Drosophila Pseudocleavage furrow membranes in the syncytial Drosophila blastoderm embryo show rapid extension and retraction regulated by actin-remodeling proteins. The F-BAR domain protein Syndapin (Synd) is involved in membra...

The compound eye of Drosophila melanogaster is configured by a differentiating wave, the morphogenetic furrow, that sweeps across the eye imaginal disc and transforms thousands of undifferentiated cells into a precisely ordered repetitive array of 800 ommatidia. The initiation of the furrow at the posterior margin of the epithelium and its subsequent movement across the eye field is controlled ...

BACKGROUND Myosin II, a conventional myosin, is dispensable for mitotic division in Dictyostelium if the cells are attached to a substrate, but is required when the cells are growing in suspension. Only a small fraction of myosin II-null cells fail to divide when attached to a substrate. Cortexillins are actin-bundling proteins that translocate to the midzone of mitotic cells and are important ...

Practical experience in the design process is an important part of undergraduate engineering education. The objective of this article is to illustrate how an ongoing research project provided design opportunities for undergraduate engineering students. Student teams in a capstone design course were engaged in the redesign and rebuilding of a mechanical plot‐scale, two‐row potato planter capable...

The cytokinetic cleavage furrow is typically positioned symmetrically relative to the cortical cell boundaries, but it can also be asymmetric. The mechanisms that control furrow site specification have been intensively studied, but how polar cortex movements influence ultimate furrow position remains poorly understood. We measured the position of the apical and the basal cortex in asymmetricall...

We studied reorganization of actin-myosin cytoskeleton at the growing ends of the cleavage furrow of Xenopus eggs in order to understand how the contractile ring is formed during cytokinesis. Reorganization of F-actin structures during the furrow formation was demonstrated by rhodamine-phalloidin staining of the cleavage furrow and by time-lapse scanning with laser scanning microscopy of F-acti...

In saline and salinity-affected soils, the global productivity sustainability of cotton are severely affected by soil salinity. High salt concentrations hinder plant growth yield formation mainly through occurrence osmotic stress, specific ion toxicity, nutritional imbalance in cotton. A number agronomic practices have been identified as potential solutions to alleviate adverse effects induced ...
