In this article we will discuss about the three main plant hormone signalling involved in differential development and other physiological process in plants:- 1. Cytokinin Signalling 2. Auxin Signalling 3. Gibberellin Signalling. 1. Cytokinin Signalling: Cytokininis have been registered as one of the key plant hormones involved in differential development and other physiological process in plants, such as cell division, [...]
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 [...]
