Document Summary
Useful for: new cultivars, endangered species, plants that are slow or dif cult to propagate. Applications: plant propagation, germplasm preservation, plant breeding, production of biochemical 2 products, scienti c research. Propagate new cultivars: horticultural quality (post harvest quality, abiotic stress tolerance, pest and pathogen resistance, crop development ( yield, pesticides) Sunday, january 29, 2017: vaccines, plastics, pharmaceuticals, biofuels. Callus culture: explant cells dedifferentiate, callus is a mass of undifferentiated plant cells, balance of pgr causes cells to differentiate (shoots -> roots-> plantlets) Microcuttings: the explant has buds (produce shoots directly), shoots are separated and rooted. Cutting propagation: how do cuttings do that? mitosis and cytokinesis! Them (amphibians): badly injured body parts, whole organs, multiple tissue and cell types with proper organization, regenerative capacity-animals. Us (mammals): cells and simple tissues. Sunday, january 29, 2017: blood cells, bones, skin, cornea, muscles, nger tips. Cutting propagation is possible because plant cells are totipotent:
