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

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.
