Dr. Pribyl knew from studies that toxins could be unintentionally created when new genes were introduced into a plant's cells.
Depending on the experimental condition, several numbers of differentially expressed genes and ratios between over- and under-expressed genes were introduced (see Methods).
Both porcine IFN-α genes were introduced into yeast expression vector PpICZα-A and expressed in Pichia pastoris.
When these genes were introduced into common rice plants, their stems rapidly elongated in deep water and withstood flooding.
Two genes were introduced into the cells – one to make them sensitive to glucose levels and a second to instruct the cell to pump out insulin when glucose levels exceeded a threshold.
Mouse hepatoma Hepa1-6 cells were transduced with retroviral vectors, in which inducible expression cassettes for the LETF genes were introduced.
Finally, a systematically chromosomally engineered E. coli strain EB243, in which 33 native genes were deleted and 5 heterologous genes were introduced, was developed.
To examine the effects of up-regulated ApL1 on transitory starch biosynthesis, the wild-type, Up1, Up2 and Up3 Apl1 genes were introduced into Arabidopsis ApL1 deficient TL46.
The corresponding reporter genes were introduced into the bacteria in such a way that they can be co-expressed along with the other genes induced by the respective sugar.
When the davAB genes were introduced into recombinant E. coli strainXQ56allowing enhanced l-lysine synthesis, 0.27 and 0.5 g/L of 5AVA were produced directly from glucose by batch and fed-batch cultures, respectively.
It is noteworthy that Rv1989c-Rv1990c froneone such MTBC-specific region showed around 90% identity with proteins encoded on a plasmid from Mycobacterium gilvum and Mycobacterium sp. KMS, raising intriguing questions about possible transmission routes by which the corresponding genes were introduced into the MTBC genomes.
