Secrets of Plant Genomes Revealed! - Potatoes vs Late Blight

The video explores the history and significance of potatoes, focusing on the devastating impact of late blight, a disease that caused the Irish potato famine. It highlights ongoing research efforts to combat this disease through genetic solutions, showcasing breakthroughs in developing blight-resistant potato strains. The potential of genomics to revolutionize agriculture and reduce reliance on harmful chemicals is emphasized, with a call to action to 'fight the blight' using advanced genetic research.

What was the primary cause of the Irish potato famine?

• A severe drought

• Late potato blight

• Economic recession

• Insect infestation

How does late blight spread among potato plants?

• Through insect bites

• Through soil erosion

• Via wind-borne spores

• By water contamination

What is the main focus of genomic research in combating late blight?

• Developing new fungicides

• Understanding plant resistance genes

• Improving soil quality

• Enhancing potato flavor

Which species provided the resistant gene for combating late blight?

• A South American tuber

• An African yam species

• A European potato variety

• A wild Mexican species

What was the outcome of the field tests for the genetically resistant potato plants?

• They failed to resist blight

• They were more susceptible

• They showed partial resistance

• They were completely resistant

How often do farmers in warmer developing countries spray fungicides to combat late blight?

• A dozen times a year

• Once a year

• More than two dozen times a year

• Twice a year

What is one major benefit of developing blight-resistant potatoes?

• Improved taste

• Increased potato size

• Reduced need for fungicides

• Faster growth rate
