LMO name
Potato modified for decreased Stomata Density
Transformation event
Lines: 1, 2, 7, 9, 11
Max-Planck-Institute of Molecular Plant Physiology
Wissenschaftspark Golm
Am Mühlenberg 1
14476 Potsdam - Golm
This transgenic potato exhibits a reduced amount of stomata (reduced by up to 55% compared to wild-type) by over expressing the SDD1 protein which decreases guard cell density This results in increased leaf roll at high light intensities and decreased tuber yield.
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.
Solanum tuberosum - Potato, SOLTU

Notes regarding the genetic elements introduced or modified in this LMO
In order to decrease guard cell density, a construct (pBinARHyg-AtSDD1) was transferred that causes the potato plants to overexpress the SDD1 protein from Arabidopsis thaliana. AtSDD1 is put under the control of the CaMV 35S promoter and the ocs terminator. An hph gene cassette consisting of the nos promoter, the hph gene, the polyadenylation signal of gene 7 from plasmid pTiAch5 from Agrobacterium tumefaciens, and the nos terminator was used as a selection marker system.
