How do you change a plant? Well—as the video to the left shows—humans have been doing it since the beginning of civilization through a process called selective breedingThe breeding of animals or plants for desirable traits or characteristics. When a farmer finds a plant with desirable traits—like bigger fruit, leafier greens, or disease resistance—that plant is bred with another plant. If the farmer is lucky, that trait is passed on to the baby plants. But, it is a long, hit and miss process that can go on for generations before the desired quality becomes consistent.
Marker assisted breedingA process using genetic fingerprinting techniques that allows plant breeders to track genes that produce a desired trait to select plants that will reproduce that trait in their offspring. Marker assisted breeding allows plant breeders to speed up the results of traditional selective plant breeding. is very similar to selective breeding, but it uses tools called genetic markers to figure out which plants would make the best parents. Genetic markers reveal the exact genes responsible for a particular trait. This lets breeders locate parents that are guaranteed to reproduce the qualities they want. Taking the guesswork out of selective breeding can save months or years in the development of an improved crop.
Genetic markers are genomic tools, but the plants produced using them are not "genetically engineered". they produce cannot be labeled as “genetically engineered”. Genetic engineeringAltering the genetic material of cells or organisms to enable them to make new substances or perform new functions, on the other hand, allows scientists to transfer DNADeoxyribonucleic acid; The ladder-like molecule that encodes genetic information, in the form of a double helix held together by bonds between base pairs from one organismAny living being capable of reproduction, growth, and maintenance to another—even between different speciesA group of organisms that can reproduce with each other. The most basic level of taxonomic classification.. These plants are called transgenicA process by which a genome scientist inserts a gene into an organism’s genome plants.
The sequencingA laboratory technique for recording the exact order of nucleotides within a section of DNA of the genomeAll the genetic material in the chromosomes of an organism, whether animal, plant, or microbe will create a base of knowledge—a “road map”—for scientists as they discover the relationships between genes and how they work. The more scientists learn about how nature develops new plant species, the better that knowledge can be applied to building better plants.
