In vivo and in vitro random mutagenesis techniques in plants [PDF]

EFSA Journal, 2021
Mutations are changes in the genetic material that may be transmitted to subsequent generations. Mutations appear spontaneously in nature and are one of the underlying driving forces of evolution. In plants, in vivo and in vitro random mutagenesis relies on the application of physical and chemical mutagens to increase the frequency of mutations thus ...
