parthenogenesis and tissue culture

Parthenogenesis and Tissue Culture - Parthenogenesis is a form of reproduction in which the ovum develops into a new individual without fertilisation. Natural parthenogenesis has been observed in many lower animals (it is characteristic of the rotif..

Tissue culture is based on the concept of cellular totipotency. That is all the multicellular organisms basically are formed from a single cell (the zygote), by repeated multiplication and differentiation. Thus a single cell can develop into a whole organism or in other words, ..

Plant Tissue Culture - It refers to culture or growing the plant tissues. Plant tissue culture is developed as a separate branch of science - ever since the potentiality of each cell or tissue of plant to grow into a separate org..

Protoplast is a cell without cell wall. In plants, the cells are invariably surrounded by thick cell wall made of cellulose and pectin. During the process of tissue culture and using it for crop improvement, cell wall acts as a barrier to induce mutations or some times to ..

Embryo mortality and seed failure associated with embryo development are most common reasons for failure of interspecific hybridization due to incompatability. In such instances, fertilization and zygote formation may not suffer but embryo development does not take place and seeds are aborted. ..

It is the conservation of wild life outside their habitat. This is achieved by perpetuation of sample population in genetic resource centres, zoos, botanical gardens, culture collection (tissue culture) or germ-plasma bank..

Controlling the disease or developing resistant varieties is time consuming and subject to variations in heritability of resistance over generations. But, disease free plants could be grown through the technique of tissue culture in a very short span of time overcoming the seas..

Two or more individuals with identical genetic make up formed from one parent by asexual reproduction are called clones. For example, daughter plants produced by strawberry runners and whole plants produced by tissue culture are clones. Similarly, the individuals formed by..
