Synthetic auxin resistance in wild radish is still an enigma

Guest author Danica Goggin finds wild radish is a problem weed in many agricultural regions. It is also very good at concealing its herbicide resistance strategies from inquisitive researchers. But with the introduction of synthetic auxin-resistant transgenic crops in North America, we need to keep chipping away at this plant’s shield of secrecy.

Organelle-originated ROS and endoplasmic reticulum responses

Ozgur et al. induce the formation of reactive oxygen species (ROS) in chloroplasts, mitochondria and peroxisomes of Arabidopsis thaliana and find that relatively low concentrations of ROS are more effective for induction of the ER stress response, and that mitochondrial and chloroplastic ROS production have different induction mechanisms for the UPR and ER stress responses.
