The potato plants were genetically modified to express the Leghemoglobin gene from [i[Lotus japonicus[/i] under the control of a tuber-specific promoter.

The genetic modification is expected to lead to increased oxygen content in the tuber at up to a depth of 2 mm below the skin, leading to enlarged lenticels and an increased tuber starch content.

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.

  • Agrobacterium-mediated DNA transfer
Some of these genetic elements may be present as fragments or truncated forms. Please see notes below, where applicable.
The papatin-B33 promoter from Solanum tuberosum mediates a tissue-specific expression of the leghaemoglobin gene in the tubers. The ocs terminator from Agrobacterium tumefaciens is used as a termination signal.

The nptII gene from Escherichia coli is expressed under the control of the promoter and terminator signal of the nopaline synthase gene from Agrobacterium tumefaciens and it was used as a selection marker.

The introduced nucleic acid is integrated in the genome of the recipient organism.
