Biotechnologists Have Isolated a Single Gene (HARDY) That Plants Use

question 114

Multiple Choice

Biotechnologists have isolated a single gene (HARDY) that plants use to regulate genes in response to stress.Scientists found that, when this gene is integrated into the genome of rice plants, the plants show a significant increase in water-use efficiency and become more tolerant of dry soil, relative to the wild type.This discovery is important because it has the potential to

• A) limit the amount of pesticides needed to grow rice.
• B) enable rice to grow in a wider range of environments.
• C) enable rice plants to produce more grain per plant.
• D) increase the vitamin A content of rice.
• E) enable rice to grow under reduced amounts of sunlight.
