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 [...]
In this article we will discuss about: 1. Process of Somatic Embryogenesis 2. Embryo Maturation and Synchronisation 3. Cultural Conditions 4. Recurrent Embryogenesis and Mass Production 5. Applications. After fertilization, zygote is transformed into adult status through a series of embryogenic processes. Despite the same genetic constituents, somatic cells on the other hand, do not reorient towards embryo production. However, [...]
