| Method |
(1) Researchers present an unambiguous and straightforward system for detection of GT events in Arabidopsis using an endogenous nuclear gene encoding protoporphyrinogen oxidase (PPO), involved in chlorophyll and heme syntheses. Inhibition of PPO by the herbicide Butafenacil results in rapid plant death. However, the combination of two particular mutations renders PPO highly resistant to Butafenacil. (2) Researchers report that expression of the yeast RAD54 gene, a member of the SWI2/SNF2 chromatin remodeling gene family, enhances gene targeting in Arabidopsis by one to two orders of magnitude, from 10^-4 to 10^-3 in WT plants to 10^-2 to 10^-1. |
