Abp1 utilizes the Arp2/3 complex activator Scar/WAVE in bristle development.
Many developmental processes rely on cortical actin dynamics; however, the mechanisms of its fine control at the cell cortex are still largely unknown. Our analyses demonstrate that the lipid- and F-actin-binding protein Abp1 is crucial for actin-driven bristle development in Drosophila melanogaster. Combined genetic, cell biological and biochemical analyses reveal that Abp1 triggers cortical A...
متن کاملAbnormal Bristle Development
We report the molecular characterization of the Posterior sex combs-Suppressor 2 of zeste region of Drosophila melanogaster. The distal breakpoint of the Aristapedioid inversion divides the region into two parts. We have molecularly mapped the lesions associated with several loss of function mutations in the Polycomb group gene Posterior sex combs (Psc) proximal to this breakpoint. In addition,...

این پژوهش با هدف "بررسی وضعیت موجود آموزش عالی مجازی در ایران و راههای توسعه و ارتقای آن " و با روش توصیفی-تحلیلی و پیمایشی صورت پذیرفته است. بررسی اسنادو مدارک موجود در زمینه آموزش مجازی نشان داد تعداد دانشجویان و مقاطع تحصیلی و رشته محل های دوره های الکترونیکی چندان مطلوب نبوده و از نظر کیفی نیز وضعیت شاخص خدمات آموزشی اساتید و وضعیت شبکه اینترنت در محیط آموزش مجازی نامطلوب است.
The development and evolution of bristle patterns in Diptera.
The spatial distribution of sensory bristles on the notum of different species of Diptera is compared. Species displaying ancestral features have a simple organization of randomly distributed, but uniformly spaced, bristles, whereas species thought to be more derived bear patterns in which the bristles are aligned into longitudinal rows. The number of rows of large bristles on the scutum was pr...
متن کاملThe role of selectins in Drosophila eye and bristle development.
Mutations in the furrowed (fw) gene of Drosophila result in defects in the development of the eye and mechanosensory bristles. The eyes are reduced in size, have furrows or crevices in the retina, and show a disturbed patterning of ommatidia. In addition, the ommatidia have an altered morphology and often contain abnormal numbers of cells. The bristles show altered structure and polarity, and a...
