3.10. Certain soil microflora can form tight associations with the root systems, or even grow within the root. Hortic Sci 31(4):140–157, Norstog K (1979) Embryo culture as a tool in the study of comparative and developmental morphology. Living plant materials from the environment are naturally contaminated on their surfaces (and sometimes interiors) with microorganisms, so their surfaces are sterilized in chemical solutions (usually alcohol and sodium or calcium hypochlorite). An alternative for obtaining uncontaminated explants is to take explants from seedlings which are aseptically grown from surface-sterilized seeds. The production of plants from seeds that otherwise have very low chances of germinating and growing, i.e. ADVERTISEMENTS: The five applications of the tissue culture are: (1) Rapid Clonal Propagation (2) Soma-clonal Variation (3) Transgenic Plants (4) Induction and Selection of Mutations and (5) Resistance to Weedicides. Introduction Plant tissue culture is an essential component of plant biotechnology. Some cultured tissues are slow in their growth. HORT689/AGRO689 Biotechniques in Plant Breeding 1 Tissue Culture Applications • Micropropagation • Germplasm preservation • Somaclonal variation & mutation selection • Embryo Culture • Haploid & Dihaploid Production • In vitro hybridization – Protoplast Fusion Living plant materials from the environment are naturally contaminated on their surfaces (and sometimes interiors) with microorganisms, so their surfaces are sterilized in chemical solutions (usually alcohol and sodium or calcium hypochlorite). Transgenic Plants 10. To cross-pollinate distantly related species and then tissue culture the resulting embryo which would otherwise normally die (Embryo Rescue). Applications of Plant Tissue […] Therefore, tissue culture regeneration can become complicated especially when many regeneration procedures have to be developed for different genotypes within the same species. The most commonly used tissue explants are the meristematic ends of the plants like the stem tip, axillary bud tip and root tip. Soil particles bound to roots are difficult to remove without injury to the roots that then allows microbial attack. Certain techniques such as meristem tip culture can be used to produce clean plant material from virused stock, such as sugarcane. In other words, it is an in vitro culture of plant cells or tissues on an artificial nutrient media under aseptic conditions, in glass containers. The three common pathways of plant tissue culture regeneration are propagation from preexisting meristems (shoot culture or nodal culture), organogenesis and non-zygotic embryogenesis. For chromosome doubling and induction of polyploidy. The knowledge obtained from plant tissue cultures has contributed to our understanding of metabolism, growth, differentiation and morphogenesis of plant cells. A balance of both auxin and cytokinin will often produce an unorganised growth of cells, or callus, but the morphology of the outgrowth will depend on the plant species as well as the medium composition. Biology and bioprocessing, as well as being a basic research tool. In: Rybczynski JJ, Davey MR, Mikula A (eds) The Gentianaceae – volume 2: biotechnology and applications. To cross distantly related species by protoplast fusion and regeneration of the novel hybrid.

Micropropagation is the rapid vegetative propagation of plants under in vitro conditions of high light intensity, controlled temperature, and a defined nutrient medium. The production of multiples of plants in the absence of seeds or necessary pollinators to produce seeds. Thereafter, the tissue is grown in sterile containers, such as petri dishes or flasks in a growth room with controlled temperature and light intensity. To cross-pollinate distantly related species and then tissue culture the resulting embryo which would otherwise normally die (Embryo Rescue). CR Biol 330:392–401, Cline MG (1991) Apical dominance. Plant tissue culture is used widely in the plant sciences, forestry, and in horticulture. Rapid Clonal Propagation: A clone is a group of individuals or cells derived from a single parent individual or cell through asexual […] Apart from mass multiplication of elites, it also provides the means to multiply and In: Thorpe TA, Yeung EC (eds) Plant embryo culture: methods and protocols, Methods in molecular biology, vol 710.
