Description
Hevea brasiliensis
was modified to express the human protamine 1 (HP1), which is a therapeutic protein which is commonly used to neutralize the anticoagulant effects of heparin during cardiovascular surgery. Expression of the HP1 gene in
Hevea brasiliensis
allows for the commercial production of this protein for pharmaceutical purposes.
Hevea expressing HP1 also harbours nptII gene that confers resistance to kanamycin, which was incorporated in the growth media to select transformed callus after co-cultivation with Agrobacterium.
Recipient Organism or Parental Organisms
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.

Notes regarding the genetic elements introduced or modified in this LMO
The four vector constructs were synthesized each containing a variable length of the heaven gene promoter (pGPTV-HP1-HevP1, pGPTV-HP1-HevP2, pGPTV-HP1-HevP3, and pGPTV-HP1-HevP4) each of which was placed upstream of the protamine 1 coding sequence.
The HP1 and nptII genetic elements were placed in an antisense orientation relative to each other within the plasmid.
The inserted genetic material is the region between the left boarder and the right boarder (T-DNA) from the Ti plasmid of Agrobacterium tumefaciens harbouring the above described gene construct.
