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, [...]
Plant propagation is carried out by sexual or asexual mode of life cycles. The asexual or vegetative reproduction produces genetically identical plants. Multiplication of several horticulturally important crops follows vegetative methods. Production of genetically identical plant cultivars by asexual method is called clonal propagation and genetically identical individuals derived from a single individual by asexual mode referred as clone. Contrast [...]
