Plant biotechnology is a cutting-edge field that harnesses genetic engineering, molecular markers, and tissue culture to enhance plant traits. By improving crop resistance to pests, diseases, and environmental stresses, this technology aims to increase yields and promote sustainable farming practices. With applications ranging from developing drought-tolerant varieties to biofortification, plant biotechnology holds the potential to address global food security challenges and reduce the ecological footprint of agriculture. Explore how these innovations are shaping the future of farming and contributing to a more resilient planet
Somatic hybridization is the technique of hybrid production through the fusion of isolated somatic(body) protoplasts under in vitro conditions and subsequent development of their product (heterokaryon) to a hybrid plant. This involves – A. Fusion of protoplast cells – 1. Treatment with NaNO3 – 1ST Rerport by power et al., 1970. In this method NaNO3 … Read more
Previously we have about of plant tissue culture (PTC) for the rapid multiplication. In PTC we can use various parts such shoot tip for shoot tip culture, leaf, etc. as explant. Imagine producing thousands of identical, healthy plants from just a small piece of tissue using PTC technique. Now let think about the plant and … Read more
To understand the protoplast isolation, lets Imagine being able to take two completely different plants—one resistant to drought, the other producing high-yield crops—and fusing them into a single super-plant. What if you could manipulate individual cells and create hybrids that nature never could? Welcome to the fascinating world of protoplast isolation, where we strip cells … Read more
What is Chloroplast Transformation? Chloroplast transformation refers to the genetic modification of chloroplast DNA (cpDNA) to express foreign genes. This process involves introducing exogenous genes into the chloroplast genome using specific vectors. Unlike nuclear transformation, which targets the nuclear DNA, chloroplast transformation directly alters the chloroplast’s genome, allowing for the production of specific proteins within … Read more
Imagine we want to study how plants grow in space or create plants with super resistance to diseases. But growing full plants can be slow, space-consuming, and hard to control. This is where callus culture come in. They allow us to grow plant cells in a lab under controlled conditions, making it easier to understand … Read more
Imagine biting into a perfectly ripe, juicy tomato. Now, imagine that same tomato, but it stays fresh and delicious for weeks rather than days. What if farmers could consistently grow fruits and vegetables that not only taste better but also last longer, reducing waste and boosting food security? Quality in agriculture isn’t just about taste; … Read more
Disease resistance Transgenic plants are the plants created through genetic engineering by transferring desired gene into target plant or crops to enhance their ability to resist specific pathogens. Ribosome-Inactivating Proteins Example – experiment Expression of Heterologous α-Thionins Ectopic Expression of PR Proteins Among the most well-characterized pathogenesis-related (PR) proteins are those exhibiting chitinase and β-1,3-glucanase … Read more
Edible vaccines are a form of oral immunization where a transgenic plant is modified to produce vaccine antigens. Edible vaccines represent a groundbreaking approach to vaccination that involves genetically modifying plants to produce antigenic proteins capable of stimulating an immune response. These vaccines are embedded in everyday foods, such as fruits or vegetables, and when … Read more
Insecticide resistant transgenic plants refer to genetically modified plants that have been engineered to possess resistance to specific insecticides.
Plant Tissue Culture (PTC), a sophisticated biotechnological tool, has revolutionized the propagation, conservation, and genetic improvement of plants. PTC involves the in vitro cultivation of plant cells, tissues, or organs in a controlled environment, providing researchers with the ability to manipulate and study plant growth and development at the cellular level Definition Plant tissue culture … Read more
