Insertion sequences.
Insertion sequences (ISs) constitute an important component of most bacterial genomes. Over 500 individual ISs have been described in the literature to date, and many more are being discovered in the ongoing prokaryotic and eukaryotic genome-sequencing projects. The last 10 years have also seen some striking advances in our understanding of the transposition process itself. Not least of these h...
متن کاملAn insertion operator preserving infinite reduction sequences
A common way to show the termination of the union of two abstract reduction systems, provided both systems terminate, is to prove they enjoy a specific property (some sort of “commutation” for instance). This specific property is actually used to show that, for the union not to terminate, one out of both systems must itself be non-terminating, which leads to a contradiction. Unfortunately, the ...
متن کاملIsolation and characterization of functional insertion sequences of rhizobia.
Rhizobia are a group of bacteria that form nodules on the roots of legume host plants. The sequenced genomes of the rhizobia are characterized by the presence of many putative insertion sequences (IS) elements. However, it is unknown whether these IS elements are functional and it is therefore relevant to assess their transposition activity. In this work, several functional insertion sequences ...
متن کاملISCce1 and ISCce2, two novel insertion sequences in Clostridium cellulolyticum.
Two new insertion sequences, ISCce1 and ISCce2, were found to be inserted into the cipC gene of spontaneous mutants of Clostridium cellulolyticum. In these insertional mutants, the cipC gene was disrupted either by ISCce1 alone or by both ISCce1 and ISCce2. ISCce1 is 1,292 bp long and has one open reading frame. The open reading frame encodes a putative 348-amino-acid protein with significant l...
متن کاملVirtual Insertion: Robust Bundle Adjustment over Long Video Sequences
Bundle Adjustment is a key process to enhance the global accuracy of the 3D camera pose and structure estimation in the framework of structure from motion over long video sequences. However, most bundle adjustment algorithms require sufficient visual feature correspondences from each camera frame to its neighboring frames in video sequences, which are hard to collect in real environments, espec...
