Discovering the Dwarfing Gene: Implications for Wheat and Other Crops

The video discusses the discovery of the RHT gene responsible for dwarfing in wheat, which has led to increased yields. Scientists at the John Innes Agricultural Research Institute identified this gene by studying Arabidopsis. The gene alters wheat's response to growth hormones, potentially boosting yields in other crops like rice. However, genetic modification remains controversial, with environmental protests highlighting concerns about contamination. Researchers aim to enhance rice yields in Asia, similar to wheat improvements.

What has been the trend in the height of wheat plants over the past 200 years?

• They have become taller.

• They have remained the same height.

• They have fluctuated in height.

• They have become shorter.

What is the role of the RHT gene in wheat plants?

• It changes the plant's color.

• It enhances the plant's ability to absorb water.

• It alters the plant's response to growth hormones.

• It increases the plant's resistance to pests.

What is the current status of the tests involving the RHT gene in rice?

• The tests have been abandoned.

• The tests are still ongoing.

• The tests have been completed successfully.

• The tests have been deemed unnecessary.

Why did environmental protesters attack a field of genetically manipulated maize?

• They wanted to promote organic farming.

• They believed it would increase pollution.

• They were concerned about contamination of nearby farms.

• They thought it would reduce crop yields.

What do researchers hope to achieve for rice farmers in Asia with the dwarfing gene?

• Increase the nutritional value of rice.

• Boost yields and income.

• Reduce the need for fertilizers.

• Enhance the taste of rice.
