AM04-1020 was developed through Agrobacterium-mediated transformation of the potato variety Kuras. The intended consequence of the genetic modification in AM04-1020 is to inhibit of the expression of granule bound starch synthase protein (GBSS) responsible for amylose biosynthesis. As a result, the starch produced has little or no amylose and consists of amylopectin, which modifies the physical properties of the starch. The csr1-2 gene encoding acetohydroxyacid synthase (AHAS) from Arabidopsis thaliana was included in the transformation process as marker conferring tolerance to imidazolinone herbicides. The T-DNA was integrated at a single locus and as a single copy in the potato nuclear genome. AM04-1020 was confirmed to be free of Agrobacterium-derived vector backbone DNA. Molecular analysis indicated that the DNA insert was stable over multiple generations of vegetatively propagated material.
