In this article we will discuss about the role of auxins and cytokinins in culture medium. Effective, speedy growth and desirable morphogenesis in tissue culture requires the presence of both auxins and cytokinins in culture medium. The relative concentration of auxins and cytokinins are often essential to bring about some kind of morphogenesis. Axillary shoot proliferation in some species may [...]
The following points highlight the six main screening strategies that are to be enforced for the selection of ideal somatic hybrids. The strategies are: 1. Microscopic Visual Selection 2. Auxin Autonomy 3. Chlorophyll Complementation 4. Biochemical Selection 5. Verification by Molecular Screening 6. Chromosomal Analysis. Strategy # 1. Microscopic Visual Selection: It is based on the fusion between coloured and [...]
In this article we will discus about the organization of plant mitochondrial DNA. The mitochondrial genome of higher plants is the largest and complex among the eukaryotes. However, the plant mitochondrial genome does not contain many genes. The complex nature of plant mitochondrial genome might be due to the presence of many chloroplast sequences in the mtDNA of higher plants. [...]
