Opis predmeta

Plant biotechnology is a discipline that encompasses a variety of in vitro methods of breeding and rapid vegetative propagation of plants, and some of these methods, such as micropropagation have been for decades routinely used in the commercial production of seedlings of various plants, especially ornamentals and fruits. Genetically modified varieties of plant species whose commercial production dates back about 20 years also are the result of research in plant biotechnology. Therefore to the techniques of recombinant DNA and genetic modification of plants, from description of the methods to the modification of different properties of different species are dedicated a number of lectures and seminar. In addition to these topics in the module Plant biotechnology students will learn the basic principles of plant tissue culture with a focus on ways to regenerate plants in vitro, the cell suspension, the preservation of genefond in in vitro conditions, the development of genetic variability through somaclonal variation and protoplast fusion, the methods of obtaining haploids and double haploids as a method of accelerating the selection process, and the use of molecular markers in plant breeding. Laboratory exercises consist of the preparation of culture media for plant tissue culture, sterilization of plant material, incision of meristem under the stereomicroscope, and inoculation of explants for micropropagation. Exam is conducted through two partial tests of knowledge or final written exam.

Opće kompetencije

After completion of lectures and exercises in this module, students are prepared to work independently eg. in a commercial laboratory for micropropagation of plants or lead such a laboratory. They are ready also for teamwork in biotechnological research laboratories in breeding houses. Based on the knowledge gained about genetically modified plants, students are ready to plan properly and keep growing conventional crops in coexistence with GM crops.

Oblici nastave

  • Lectures
  • Laboratory practice/exercises
    Laboratory exercises are implemented through four exercises for two hours in small groups. During exercises students prepare culture media for plant tissue, prepare explants for the initiation of culture in vitro (surface sterilization), subcultivate nodal segments for micropropagation by axillary branching, and isolate the meristem for setting in culture
  • Seminars
    Independent work at home, and then as the work in the classroom; students divided into two groups debate about genetically modified plants. For the quality of the debate student's preparation in groups is necessary according to previously obtained materials
