Selection of Somatic Hybrids: 6 Strategies | Biotechnology

The following points highlight the six main screening strategies that are to be enforced for the selection of ideal somatic hybrids. The strategies are: 1.  Microscopic Visual Selection 2. Auxin Autonomy 3. Chlorophyll Complementation 4. Biochemical Selection 5. Verification by Molecular Screening 6. Chromosomal Analysis. Strategy # 1. Microscopic Visual Selection: It is based on the fusion between coloured and [...]

Plant Signal Transduction | Biotechnology

In this article we will discuss about:- 1. Single Transduction Pathways in Plants 2. Mechanism of Signal Transduction 3. Calcium Signalling in Plants 4.Other Plant Signalling Molecules Single Transduction Pathways in Plants: Plant cells, due to their sessile nature, are able to interact with its surrounding environ­ment. Plants use various environmental signals to alter their mode of developmental morphol­ogy. Throughout [...]

Types of Marker Genes | Genetics

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 [...]
