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 potato blight, which caused the Irish potato famine. It highlights the resurgence of this disease and the efforts of researchers to find genetic solutions. The narrative follows the discovery of a resistant gene from a wild Mexican species, showcasing the potential of genomics to combat plant diseases and reduce chemical use in agriculture. The video emphasizes the importance of understanding plant genomes to improve crop resilience and address environmental and health issues.

What was the primary cause of the Irish potato famine?

• Late potato blight

• Economic collapse

• A severe drought

• Insect infestation

How quickly can late blight destroy a potato field once it is infected?

• 15 to 20 days

• 1 to 2 days

• 3 to 5 days

• 7 to 10 days

What is the main focus of researchers at Genome Research facilities regarding late blight?

• Improving potato taste

• Finding a genetic defense

• Developing new fungicides

• Increasing potato size

Which species provided the gene for blight resistance in potatoes?

• Wild American species

• Wild Mexican species

• Wild Peruvian species

• Wild Irish species

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

• They grew larger than normal

• They remained healthy and green

• They showed partial resistance

• They were completely destroyed

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

• Twenty-four times a year

• Once a year

• Six times a year

• Twelve times a year

What is one of the broader implications of genomic research in agriculture?

• Increasing the cost of farming

• Slowing down plant growth

• Decreasing crop diversity

• Reducing the need for pesticides
