Effects of Photosystem‐II‐Interfering Herbicides Atrazine and Bentazon on the Soybean Transcriptome

The Plant Genome, Volume 2, Issue 2, July 2009., 2009
Atrazine and bentazon are both photosystem‐II (PSII)–inhibiting herbicides that interfere with photosynthetic electron transport, provoking oxidative stress. While atrazine is lethal to soybean [Glycine max (L.) Merr.], bentazon does not kill soybean because of the capability of soybeans to metabolize the herbicide.
