Agrobacterium tumefaciens (crown gall) produces tumours in plants such as tomatoes and sunflowers. The bacterium 'injects' some of its DNA into the cells of the host transforming them into cancerous cells. It also causes these cells to produce substances needed by the bacterium for growth. In this Genetic Modification Kit students inject sunflower plants with Agrobacterium to induce gall formation and subsequently re-isolate the bacterium and grow it on agar plates.Please note that our Genetic Modification Kit is only suitable for use in education.Contents:Culture of AgrobacteriumSunflower seedsNutrient brothNutrient agarSyringes needlesSodium thiosulphateFull instructionsSufficient material for 5 students/student groups.
