NettetWe propose that HfaE is a novel holdfast anchor protein and that HfaE functions to link holdfast material to the cell envelope. IMPORTANCE For surface attachment and … Nettet12. feb. 2024 · Caulobacter crescentus produces a specialized structure at one of its cell poles called the holdfast that enables attachment to surfaces. Previous studies have shown that the holdfast is composed of carbohydrate-based material and identified a number of genes required for holdfast development.

The unstalked crinoids … NettetThe complicated body, in some ways similar in appearance to that of higher plants, has a large rootlike holdfast for attachment to the ocean floor, a stemlike stipe for the internal transport of organic material, and long branching stalks with blades that stay afloat by means of gas bladders. toy story 1 english subtitles

Development of surface adhesion in Caulobacter crescentus

NettetWe show that the holdfast is essential but not sufficient for optimal attachment. Rather, adhesion in C. crescentus is a complex developmental process. We found that the attachment of C. crescentus to surfaces is cell cycle regulated and that growth or energy or both are essential for this process. Nettetholdfast.
