Studies says loss of small RNA molecule is key to rice domestication
06 November 2018 Current Affairs: The study carried out at the National Centre of Biological Sciences (NCBS), Bengaluru said that The domestication of rice can be tracked to the loss of a small RNA molecule (miR397). This can be used to improve crops.

Indica rice, a subspecies of Oryza sativa, is domesticated from two wild species Oryza nivara and Oryza rufipogon. Studies found that the genomes did not show variation proportional to the changes in the phenotype. Researchers failed to identify genes responsible for the changes observed in domesticated Indica rice as compared to its wild relatives. The answer lay in regulatory molecules known as the small RNAs.
