Fragmentation is a very common type of vegetative reproduction in plants. Many trees, shrubs, nonwoody perennials, and ferns form clonal colonies by producing new rooted shoots by rhizomes or stolons, which increases the diameter of the colony. If a rooted shoot becomes detached from the colony, then fragmentation has occurred. There are ...
Reproduction takes place asexually by fragmentation. Usually the filament breaks into a number of fragments called hormogonia. Each hormogonium consist of one or more cells and grows into a filament by cell division in one direction. [1] As a result of recent genetic analyses, several new genera were erected from this genus, e.g. Tenebriella. [3]
Cyanobacterial cell division and cell growth mutant phenotypes in Synechocystis, Synechococcus, and Anabaena.Stars indicate gene essentiality in the respective organism. While one gene can be essential in one cyanobacterial organism/morphotype, it does not necessarily mean it is essential in all other cyanobacteria.
This type of asexual reproduction is referred to as fragmentation. It is a means of asexual propagation in plants . These structures are commonly found in fungi , algae , liverworts and mosses , but also in some flowering plants such as pygmy sundews and some species of butterworts .
The current model produced by the Russian Federation is the RPG-7V2, capable of firing standard and dual high-explosive anti-tank (HEAT) rounds, high explosive/fragmentation, and thermobaric warheads, with a UP-7V sighting device fitted (used in tandem with the standard 2.7× PGO-7 optical sight) to allow the use of extended range ammunition.
A fragmentation tree is a representation of the fragmentation process similar to “fragmentation diagrams” created by experts. The fragmentation tree annotates the MS2 spectrum by providing a molecular formula for each fragment peak. Peaks that do not receive an annotation are considered noise peaks.
Schematic diagram of cellular growth (elongation) and binary fission of bacilli. Blue and red lines indicate old and newly generated bacterial cell wall, respectively. (1) growth at the centre of the bacterial body. e.g. Bacillus subtilis, E. coli, and others. (2) apical growth. e.g. Corynebacterium diphtheriae. This is bacterial proliferation.
In mass spectrometry, fragmentation is the dissociation of energetically unstable molecular ions formed from passing the molecules mass spectrum.These reactions are well documented over the decades and fragmentation patterns are useful to determine the molar weight and structural information of unknown molecules.
