Secrets of Plant Genomes Revealed! (Entire Show)

Watch the entire show! (Note: This may take a few minutes to download).

Intro

What do oxygen, potato chips, and the tires on your car have in common? The answer is more important than you might think!

Chapter 1: What the Heck Is a Genome?

GenomicsThe study of genes and their functions is changing the face of biology. And whether you know it or not, it's changing how you live. Find out how what the heck a genomeAll the genetic material in the chromosomes of an organism, whether animal, plant, or microbe is.

Chapter 2: The First Plant to Be Sequenced

Meet a scruffy, little plant that has made history. ArabidopsisThe first plant to have its genome completely sequenced and mapped. A member of the mustard family, Arabidopsis thaliana, more commonly known as “mouse-eared cress” is a fast growing weed used in countless biological research facilities because of it relatively small and simple genome. is the first plant to have its entire genomeAll the genetic material in the chromosomes of an organism, whether animal, plant, or microbe sequenced and mapped. What makes it so special?

Chapter 3: Corn—The Dynamic Genome

Meet the mutants! Corn is king in America, and it's genomeAll the genetic material in the chromosomes of an organism, whether animal, plant, or microbe tells a pretty fascinating story. See how scientists use corn mutations to decode its genome.

Chapter 4: Cotton—Building a Better Plant

How did cotton genes make your cotton jeans? It's an intercontinental love story. Meet the African and Mexican ancestors that made your favorite T-Shirt possible.

Chapter 5: Potatoes vs. Late Blight—Plants at War and Peace

Death, destruction, and technology… It's not a movie. It's the dramatic story of potatoes and late blightA plant disease that attacks both potatoes and tomatoes. Late blight is caused by a fungal pathogen or germ that survives from one season to the next in infected potato tubers.. The blight has devastated crops, but genomicsThe study of genes and their functions is fighting back. See what researchers on the cutting edge are doing to fight the blight!

Summary

Once we have the genomeAll the genetic material in the chromosomes of an organism, whether animal, plant, or microbe mapThe relative positions of genes on a DNA molecule of a plant, we can ask more exciting questions, make more changes, and achieve more improvements. What does the genomicsThe study of genes and their functions revolution mean for you?
