The genetically modified tobacco plants constitutively express a shortened version of the xylanase gene from Clostridium thermocellum that is N-terminally fused to the signal peptide of the proteinase inhibitor II from potato, which leads to the gene product being into the apoplast.

Xylan is a component of the hemicellulose of plant cell walls. It is degraded by xylanases. The transport into the apoplast removes the xylanase from the protease-rich intracellular space, preventing it from being degraded.

Despite the presence of the xylanase, no alteration in plant growth, susceptibility to pathogens and cell wall composition was observed in the transgenic tobacco plants.
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.
