"Rice has been cultivated for more than 9,000 years. ...........At least 114 countries grow rice. Asian farmers produce about 90% of the total, with two countries, China and India, growing more than half the total crop. ...........Rice has the smallest genome size of all cereals, of around 430 million base pairs of DNA. Rice is considered a model system for plant biology largely due to its compact genome (430 million base pairs on its 12 chromosomes)..........Sequencing of its genome has opened a way for developing new varieties of rice to combat the pests and also to grow with less water."
There's a lot more in this article including the complete history of the genome sequencing of rice going back to 1991 when it started. Here's a link for you.
