The genome sequences of two rice chromosomes have been published in this week’s Nature, providing information that is crucial for researchers who want to use genetic information to modify rice for agricultural purposes.

Earlier this year, draft sequences of the two main subspecies of cultivated rice, Oryza sativa, were published (see Scientists crack rice code). The new results detail the complete sequences of rice chromosomes 1 and 4, with an accurate readout of the positioning of genes in rice DNA.

The authors say their analyses show how crucial ‘finished’ genome sequences are to academic researchers.
