Cotton LL25xMON15985


Trait: Tolerance to glufosinate-containing herbicides (BastaŽ, RelyŽ, FinaleŽ, and LibertyŽ) and a resistance to lepidopteran pests.
Inserted gene:
pat-gene Source: Soil bacterium (Streptomyces viridochromogenes)

Function: the pat gene codes for the enzyme Phosphinothricin-Acetyltransferase (PAT) and leads to increased tolerance to glufosinate-containing herbicides.

cryIA(c)+cry2ab-gene Source: Bacillus thuringiensis kurstaki

Function: These genes encode the Bt-toxins Cry1A(c) and Cry2Ab2, which confer resistance to lepidopteran pests of cotton, such as tobacco budworm (Heliothis virescens), cotton bollworm (Helicoverpa zea), pink bollworm (Pectinophora gossypiella), and soybean looper (Pseudoplusia includens).

Markergene nptII (gene conferring resistance to kanamycin), gus-gene (reportergen or visual marker gene)
Methods for the genetic modification: Agrobacterium tumefaciens-mediated gene transfer
