Small change
CDC researchers identify espw mutant by comparing the genetic series of new 729 isolated E -colony Stress – dubbed Ripx 01 – 2,027 in the genetic series of E -colony O157: H7 isolated. Of the 729 Repexh01 tension, both were deleted in the same nucleotide in ESPW (the remaining two had ambiguous sequences), while the deleted non -Ripx was in less than 4 % of 01. E -colony Stress search shows that small change can be a genetic signature of stress, and an important disease can provide a benefit to its perseverance in protein.
For now, it is unclear what this benefit can be. Deleting the same DNA base (one editor) is replaced by the three sequential protein code frame for the rest of ESPW. This can result in a small protein. It can also cause molecular machinery that translates to the genetic code, which causes different length proteins. In any case, the less likely to be deleted is the result of fully active Espw protein.
CDC researchers suggest that this may help E -colony When it is on lettuce and other production. For example, ESPW can encourage immune response from an affected plant that to prevent bacterial attacks, causes stomata -leaves levels on the surfaces of the leaves. Thus, can help cut the espw E -colony In the ongoing race of weapons between bacteria and its host – stealthily. Another possibility is that the ESPW Hop can act like W -One, which causes a more severe infection in the tissues of the plant, which can reduce the possibility that these affected leaves are harvested and deliver it to grocery stores and Etpurgers. Thus, can help cut the espw E -colony Move it to its human victims.
Finally, additional research will be needed to understand what is happening. As the CDC researchers concluded: “The role of a single pair in the colonialism of this tension and the survival of leafy vegetables can provide valuable insights.”
