Depending on the nature of selection, marker genes are divided into two types: 1. Selectable Marker Genes 2. Reporter Genes. Type # 1. Selectable Marker Genes: One of the constraints in plant transformation technique is the obtaining of transformed plants with less frequency. Thus, it is indispensable to select transformed cells under cultural conditions itself. […]

Construction of Genomic Library | Genetics
Article Shared by
A genomic library contains all the sequences present in the genome of an organism. In the construction of genomic libraries it is feasible to use vectors that could accommodate large size of inserts. The first step in the construction of genomic library is the isolation of genomic DNA, and entire DNA is subjected to restriction […]
Process of T-DNA Transfer | Genetics
Article Shared by
In this article we will discuss about the process of T-DNA transfer. Once plant exudates activating expression of vir genes and Agrobacterium attach to the plant cells, the T-DNA region in the Ti plasmid undergo excision process to transfer into the plant cells. Excision process involves active participation of vir genes such as virD, virC […]
