Definitions

  • the present invention relates to genetically engi- neered modification of potato, resulting in the formation of an increasing amount of amylose-type starch as compared to amylopectin-type starch in the potato.
  • the genetically engineered modification implies the insertion of a gene fragment into potato, said gene fragment comprising tran- scription start and a part of the gene coding for the for ⁇ mation of branching enzyme (BE gene) in potato, inserted in the antisense direction, together with a tuber-specific promoter.
  • BE gene branching enzyme
  • starch In the potato tuber, starch is the greatest part of the solid matter. About 1/4 to 1/5 of the starch in potato is amylose, while the remainder of the starch is amylo- pectin. These two components of the starch have different fields of application, and therefore the possibility of producing either pure amylose or pure amylopectin is most interesting.
  • the two starch components can be produced from common starch, which requires a number of process steps and, consequently, is expensive and complicated.
  • BE branching enzyme
  • Branching enzyme (BE) in potato is a monomer protein, i.e. it is a single enzyme form.
  • the molecular weight of potato BE varies between 79 and 103 kD, depending on the purifying process used. There are indications that potato BE should consist of several forms, but presumably several forms are degradation products from the actual protein (Vos-Scheperkeuter, 1989; Blennow & Johansson, 1990).
  • the invention comprises a method of sup ⁇ pressing formation of amylopectin-type starch in potato, whereby the potato tubers form a varyingly increased amount of amylose-type starch.
  • amylose Physical modification of the amylose can be effected by e.g. cylinder-drying or extrusion.
  • Example 5 Chemical derivatisation of amylose Amylose is sludged in water to a concentration of 20-50% by weight. The pH is adjusted to 5.0-12.0, and sodium hypochlorite is added so that the end product obtains the desired viscosity. The reaction temperature is set at 20-45°C. When the reaction is completed, the pH is adjusted to 4-8, whereupon the end product is washed and dried. In this manner, oxidised starch is obtained.
  • Example 6 Physical derivatisation of amylose
  • SEQ ID No. 1 Sequenced molecule: genomic DNA Name: Promoter for the GBSS gene from potato Length of sequence: 629 bp
