Herbicide-tolerant Indian mustard (RF3 juncea canola)
EN
RF3
No
The modified Indian mustard (Brassica juncea; RF3 juncea canola) was produced via conventional crossbreeding to transfer the genetic modification from InVigor™ canola (Brassica napus; RF3) to unmodified Indian mustard. Thus, the modification is expected to confer tolerance to glufosinate herbicides through the expression of Streptomyces hygroscopicus phosphinothricin N-acetyltransferase. In addition, the modified Indian mustard contains the male fertility restoration system based on the Bacillus amyloliquefaciens barstar, which inhibits the activity of the RNase barnase.

The term “Recipient organism” refers to an organism (either already modified or non-modified) that was subjected to genetic modification, whereas “Parental organisms” refers to those that were involved in cross breeding or cell fusion.

The modified Indian mustard contains two gene cassettes: Bacillus amyloliquefaciens barstar and Streptomyces hygroscopicus phosphinothricin N-acetyltransferase (bar).

The bar coding sequence is under control of Arabidopsis thaliana ribulose-1,5-bisphosphate carboxylase small subunit (rbcS) protomer and A. tumefaciens transcript 7 gene 3' untranslated region.

The barstar coding sequence is under control of the Nicotiana tabacum TA29 promoter and Agrobacterium tumefaciens nopaline synthase (nos) terminator. Despite the presence of the barstar 3' untranslated region, transcription is expected to be terminated by the nos terminator. Due to the pollen-specific nature of the promoter, expression of barstar is only expect in pollen.

A second barstar cassette is present with the same genetic elements as above. The TA29 promoter present in this second is truncated, but functional. The cassette terminated by a nos terminator. A partial rbcS promoter is also present, but not functional.

Note:
  • On the N-terminal, two codons of the wild-type bar coding region have been substituted for the codons ATG and GAC.
  • Southern blot and PCR analysis indicated that the LMO contains one complete copy of the transformation cassette with a second partial cassette, arranged in an inverted repeat orientation centered around the left border. The partial repeat contains the functional genetic elements for the barstar cassette, but the rbcS promoter is non-functional.
  • The exact genetic element sizes for the truncated promoters in the second partial repeat are not available and thus have not been indicated.
