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. [...]
In this article we will discuss about:- 1. DNA Organization in Nucleus 2. General Properties of DNA 3. Variation of Genomic Size among Plants 4. Plant Repetitive 5. Telomere Repeat Sequence 6. Single Copy Sequence 7. Fine Structure of Plant Gene 8. Genes for Ribosomal RNA 9. Palindrome Sequences. The spherical or ovoidal plant cell DNA resides in a nucleus, [...]
