Chymosin-producing safflower

IND-10003-4 × IND-10015-7
Yes
IND-1ØØØ3-4 × IND-1ØØ15-7
The safflower (Carthamus tinctorius L.) created through cross breeding of two modified parental lines for the production of Bos taurus chymosin in seed tissues. The enzyme is used in the production of cheese products to coagulate (clot) milk. In addition to the production of the enzyme, the safflower expresses Streptomyces viridochromogenes phosphinothricin N-acetyaltransferase for glufosinate selection during transformation.

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.

Genetic elements related to IND-10003-4
The IND-10003-4 genome contains two gene cassettes: Bos taurus chymosin (cym) and Streptomyces viridochromogenes phosphinothricin N-acetyltransferase (pat).

The cym coding sequence is under control of the Phaseolus vulgaris phaseolin promoter and terminator. The coding sequence additionally contains a pathogenesis-related protein R transit peptide, which will direct the CYM protein to the apoplast of seed tissues. Expression of the cym coding sequence is expected to be restricted to seed tissues.

The pat coding sequence is under control of the Petroselinum crispum ubiquitin promoter and terminator. Due to the constitutive nature of the promoter, high levels are transcription are expected.

Note:
  • Southern blot and PCR analyses indicated that the genome contain a single T-DNA insertion.
  • Next generation sequencing analysis indicated that a duplication of 1064 basepairs of the phaseolin promoter. The sequence is in the reverse orientation and lacks the region responsible for the start of transcription. Therefore, this duplicated sequence is not expected to have transcriptional function.
  • Next generation sequencing additionally indicated that functional phaseolin promoter contained a 514 basepair deletion distal to the transcriptional start region. However, expression of cym does not seem to be compromised. 
  • Sequencing indicated that none of the plasmid backbone sequences were integrated into the safflower genome.


Genetic elements related to IND-10015-7
The IND-10015-7 genome contains two gene cassettes: Bos taurus chymosin (cym) and Streptomyces viridochromogenes phosphinothricin N-acetyltransferase (pat).

The cym coding sequence is under control of the Phaseolus vulgaris phaseolin promoter and terminator. The coding sequence additionally contains a pathogenesis-related protein R transit peptide, which will direct the CYM protein to the apoplast of seed tissues. Expression of the cym coding sequence is expected to be restricted to seed tissues.

The pat coding sequence is under control of the Petroselinum crispum ubiquitin promoter and terminator. Due to the constitutive nature of the promoter, high levels are transcription are expected.

Note:
  • Southern blot indicated that the genome contain a single T-DNA insertion.
  • Sequencing and PCR analyses indicated that the sequences are intact and without rearrangements.
  • Sequencing analysis additionally indicated that no vector backbone sequences were integrated into the safflower genome.
