In this article we will discuss about the significance of protoplast culture. Cell Modification by DNA Uptake: The isolated plant protoplasts are best suited for the introduction of foreign genetic material. Protoplast acts as an efficient receptor for the uptake of foreign DNA. Protoplast can be regenerated into the whole plant and this is indispensable for genetic manipulation. The ratio [...]
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. Selection is based on the [...]
According to Murashige of California University, micro-propagation is distinctly divided into five stages. Stage 0 — Mother Plant Selection: Before initiation of micro-propagation, selection of suitable mother plant is crucial in the whole exercise of propagation. Generally, disease free mother explant is selected for the micro-propagation to reduce contamination of cultures. Certain growth parameters of mother plant can be improved [...]
