In this article we will discuss about the process of androgenesis, explained with the help of suitable diagrams. A. In Vitro Pathways of Androgenesis: The anther or pollen normally starts undergoing in the pathway of androgenesis within 2 weeks and it takes about 5-8 weeks to obtain complete plantlets. Haploid plants are formed in two ways: (i) Direct Androgenesis: Embryos [...]
The following points highlight the top ten applications of haploid plants. The applications are: 1. Development of Pure Homozygous Line 2. Use in Hybrid Development 3. Significance in Early Release of Varieties 4. Hybrid Sorting in Haploid Breeding 5. Induction of Mutagenesis 6. Induction of Genetic Variability 7. Generation of Exclusively Male Plants and a few others. Application # 1. [...]
The below mentioned article provides a study note on transgenic plants. The application of recombinant technique for horizontal transfer of gene in plant system has several limitations. Plant genome is exceedingly complex, involving a huge amount of DNA, which can accommodate sequences equivalent to 6-7 million genes in an average crop plant. Several genes are located outside the nucleus, namely [...]
