 The CAMV35S promoter is known to be active in both plants and bacteria. Even the stable model protein DS red accumulates at low levels in both bacteria and plants. However, the levels are too low to cause any harm to either the operator or the environment. Additionally, the amount of A tumor facions present during the process is minimal and no toxins are produced by the bacteria. Therefore, transient expression is considered safe from a bacterial handling perspective. This article was authored by Matias Nodler, Paul Wynman Reunis and Johannes Felix Bile.
