A. The rice genome is very unique and contains genes not found in other plants

B. The rice genome is very large compared to the DNA of other grains and so more genes will be identified

C. It can identify genes associated with disease resistance, growth capacity, etc

D. It has a rapid life cycle and has many identifiable mutations
