Principles of Plant Biotechnology

GPBR 311 is a plant biotechnology course that introduces tissue culture, micropropagation, somatic hybridization, recombinant DNA methods, molecular markers, marker-assisted breeding, and biotechnology regulation.

Plant biotechnology means using laboratory-based biological tools such as tissue culture, molecular markers, and gene manipulation techniques to study plants and improve crop performance.

Tissue culture is the in vitro growth of plant cells, tissues, or organs on nutrient media, and it is important because it enables rapid multiplication, disease-free plant production, embryo rescue, and other improvement tools.

Micropropagation is the rapid clonal multiplication of plants under sterile laboratory conditions from a small explant, often used to produce uniform and disease-free planting material.

Somatic hybridization is the fusion of protoplasts from different plants to combine genetic material across sexual barriers, while cybrids are cells or plants with a mixed cytoplasmic background and a more limited nuclear contribution.

PCR is a method used to amplify specific DNA sequences, and it is important because it supports gene analysis, marker studies, DNA fingerprinting, and many other molecular applications in crop improvement.

Molecular markers are DNA-based identifiers linked to regions of the genome, and marker-assisted breeding uses them to track useful traits more precisely and speed up selection in breeding programmes.

Biotechnology regulations are included because plant-biotech applications involve biosafety, research standards, and rules governing the development and use of transgenic or other advanced biological technologies.
