a) In transformation, the cell takes up DNA directly from the environment. (pressbooks.pub)

When prokaryotes and eukaryotes reproduce asexually, they transfer a nearly identical copy of their genetic material to their offspring through vertical gene transfer. (pressbooks.pub)

As a consequence, they often lack sufficient genetic variability to adapt to other environments whilst maintaining a high yield. (allindianpatents.com)

On gel electrophoresis, plasmid DNA and maize DNA were shown to be degraded rapidly by rumen fluid or silage effluent within one minute, but both were incompletely degraded after at least l h exposure to saliva. (gmwatch.org)
Plasmid DNA exposed to saliva for 24h was still capable of transforming E. coli to ampicillin resistance, but at low efficiency: 20 cfu (colony forming units) per ml compared with 1.6 x103 cfu per ml after 24h in sterile water. (gmwatch.org)

Broad Spectrum Resistance to ssDNA Viruses Associated with Transgene-Induced Gene Silencing in Cassava. (be-mindful.de)
siRNAs are produced from double-stranded RNAs of viruses and transposable elements, which are processed by the dicer nuclease, one of the essential components of the RNA-Induced Silencing Complexes (RISCs) [ 7 - 9 ]. (biomedcentral.com)
It is also predicted that genomically recoded organisms are immune to infection by viruses, under the assumption that phages and their hosts must share a common genetic code ( 6 ). (scienceintheclassroom.org)

In this review we discuss these major challenges and describe methodological approaches that show promise for resolving ambiguity in fungal taxonomy by improving discrimination of genetic and functional traits. (frontiersin.org)
Herbicide resistance and insecticide tolerance has been perfected whereas the stacking of traits is being achieved especially to combat abiotic and biotic stresses, individually and their combinations (Rao et al. (biomedcentral.com)

There are two major, distinct forms of regulatory small RNAs involved in eukaryotic gene silencing: small interfering (si) RNAs and micro (mi) RNAs. (biomedcentral.com)

A heritable chemical modification of DNA (replacement of cytosine by 5-methyl cytosine) that, when present in a control region, usually suppresses expression of the corresponding gene. (nationalacademies.org)

iv) After fulfilling these three criteria, the product must be biosafe: not produce mammalian toxins that affect users and consumers, and have a host range that does not include crops and beneficial organisms, and in most cases that it will not spread from application sites or have environmental residues beyond those needed to control the target pest.

Insect-resistant maize line CG00526-176 contains three bacterial genes: the cry1A(b) specific to lepidopterans, the bar gene conferring tolerance to glufosinate, and a bla gene encoding TEM-1 b-lactamase (ampicillin resistance). (gmwatch.org)
There are at least two copies of crylA(b) and bla genes integrated into the DNA of maize line CG00526-176. (gmwatch.org)
Both pUC18 plasmid and transgenic maize DNA were used in the experiments. (gmwatch.org)
350bp) were still found in rumen fluid up to 30 mins for the plasmid and up to1 min for maize DNA. (gmwatch.org)
684 bp) from plasmid and maize DNA were found up to 30 min incubation in silage effluent, and up to 24h and 2 h respectively in saliva. (gmwatch.org)
1914bp) in maize DNA could be found up to 1 min with rumen fluid, 5 min with silage effluent, and 60 min with saliva. (gmwatch.org)

This will facilitate the functional analyses of genes as well as metabolic engineering for the production of biofuels and bioproducts from biomass. (biomedcentral.com)

The evidence for horizontal gene transfer is accumulating. (gmwatch.org)
E. coli strain DH5a was the test micro-organism for horizontal gene transfer. (gmwatch.org)
In summary, horizontal gene transfer can occur before the DNA is completely broken down, even when the breakdown is rapid, as in the rumen or in silage. (gmwatch.org)
DNA breakdown is extremely slow in saliva, and hence the oral cavity will be a very important site for horizontal gene transfer. (gmwatch.org)
Typically, when we consider genetic transfer, we think of vertical gene transfer, the transmission of genetic information from generation to generation. (pressbooks.pub)
Vertical gene transfer is by far the main mode of transmission of genetic information in all cells. (pressbooks.pub)
Given the extreme toxicity of some of the toxins of these TA systems, we were curious how the cell silences toxins, if the antitoxin is inactivated or when toxins are obtained without antitoxins via horizontal gene transfer. (preprints.org)
Given the apparent ubiquity of the canonical genetic code, the design of genomically recoded organisms with noncanonical codes has been suggested as a means to prevent horizontal gene transfer between laboratory and environmental organisms ( 8 - 10 ). (scienceintheclassroom.org)

Movement of these genes from 1 organism to another or an increase in their expression, for example, can trigger a resistance phenotype ( 1 ). (cdc.gov)
