Question: Which of the following was the first transgenic crop to be developed?
A Rice
B Cotton
C Tomato
D Tobacco
Answer: Tobacco
| Aspect | Description |
| Name of plant Species | Tobacco |
| Scientific name | Nicotiana tabacum |
| Researchers | Dr. Mary-Dell Chilton and her team at Washington University in St. Louis, USA. |
| Year of Transgenesis | 1982 |
| Achievement Significance | The first successful attempt to genetically modify a plant, marking the beginning of transgenic crop research. |
| Genetic Modification | The tobacco plants were genetically engineered to express antibiotic resistance genes as a marker for successful genetic transformation. |
| Transformation Method | The researchers used a naturally occurring soil bacterium, Agrobacterium tumefaciens, as a vector to introduce the foreign DNA into the tobacco plant’s genome. |
| Purpose of Research | To demonstrate the feasibility of introducing foreign genes into plant cells and achieving s <table expression. |
| Scientific Contribution | Dr. Mary-Dell Chilton’s pioneering work laid the foundation for biotechnology in agriculture and earned her recognition as a key figure in the field of genetic engineering. |
