Hygromycin Resistance

Hygromycin resistance

In vegetatively propagated plants, it is almost impossible to eliminate a transgene integrated into the genome via segregation. However, the frequency of targeted mutagenesis via transient expression of Hygromycin resistance and guide RNA is not sufficient for practical application to crop species in most cases. In addition to Cas9 from Streptococcus pyogenes SpCas9which is the Here most commonly used in diverse organisms, Cas9 from different species, Cas9 variants and different types of Cas nucleases, such as Cas12a, have been characterized and developed for customized hygromycin resistance of DNA sequences for review, see Anzalone et al.

The efficiency of genome editing by these Cas9 variants and base editors is reported to be low compared with that of targeted mutagenesis via Continue reading nuclease in several types of plants Kang et al. Because obtaining mutant plants by transient expression of a Cas9 variant or base editor is considered difficult except hygromycin resistance the mutation confers a selectable trait, it is thought preferable to integrate expression cassettes for these nucleases or base editors into the host genome so that they are expressed stably and continuously during some period of time.

The piggyBac transposon was first identified in the cabbage looper moth, Trichoplusia ni Cary hygromycin resistance al.

Thus, it has been used for transgenesis and insertional mutagenesis in a wide hygromycin resistance of species, such as Drosophila melanogaster Horn et al. In addition, a transgene delivery and excision system mediated by piggyBac transposon has been developed successfully to reprogramme mammalian somatic cells to a pluripotent state, thereby creating induced pluripotent stem iPS cells Woltjen et al.

Finally, to leave only the targeted mutation in the target gene, the piggyBac transposon is excised precisely from the host genome by transient expression of PBase Step 3.]

Additional Information Recommendations Hygromycin B is a water-soluble antibiotic purified from the bacterium Streptomyces hydroscopicus. Hygromycin B acts by binding to the 80S subunit of the bacterial ribosome and inhibiting protein synthesis. Resistance to Hygromycin B is conferred by the E. Other Choices and More Information We offer a wide range of antibiotics and antimycotics in both powder and liquid formats.

Mutants were inoculated onto MM lOmM nitrate 3: within 2cm of the petri dish edge. Growth was assessed - ; j after 14days incubation. Cell free extracts of C. Img reduced glutathione. Nitrite determinations were performed as in Wray and Filner Spores of C. Floating protoplasts were removed and washed three times in mM KCl, with centrifugation at rpm for lOmins. Protoplasts were collected by centrifugation at rpm for lOmins and washed three times in mM KCl. Alterations in this transformation procedure are explained in the results section. Transformation was performed using an adaptation of the method of Johnstone et al
