Selection of Transgenic Rice Plants Using a Herbicide Tolerant Form of the Acetolactate Synthase Gene
Time of Update: 2021-01-12
Acetolactate synthase (ALS) is an enzyme in the biosynthetic pathway for branched-chain amino acids, and bispyribac-sodium (BS), a pyrimidinyl carboxy herbicide, is a well-known inhibitor of ALS activity.
Because this selection marker cassette is originally from the rice endogenous genome, it can be expected to be publicly acceptable.
