Metribuzin resistance in photoautotrophic Chenopodium rubrum cell cultures. Characterization of double and triple mutations in the psbA gene

FEBS Lett. 1993 Aug 23;329(1-2):43-6. doi: 10.1016/0014-5793(93)80189-2.

Abstract

Sequence analysis of eight metribuzin-resistant mutants of photoautotrophic Chenopodium rubrum cell cultures revealed new mutations in the psbA gene coding for the 32 kDa herbicide binding protein. Mutants were found to possess either two or three changes in the amino acid sequence of the D1-protein between positions 219 and 272.
