Traditionally, in many places in Asia, the bran was fed to swine and piggeries, which were often located in the direct neighborhood of the mills. Utilization of these crops has benefited the growers and the environment by greatly reducing the use of chemical insecticides (13).

While domestication is a long-term process and continues today, a single event during domestication, the selection of the non-shattering sh4 allele, resulted in rice becoming a species dependent on humans for survival - domesticated. In the last two decades, considerable research effort has been invested to introduce insecticidal crystal protein genes from Bacillus thuringiensis (Bt) into crops including rice. Recent research related to evolution in the primary gene pool of rice, which consists of Oryza species with the A-genome, provides new perspectives related to current and past eco-genetic setting of rice and its wild relatives and fresh insights into rice domestication.

Here the apparent contradictions between a single origin of Asian rice and deep genetic divisions seen in rice germplasm are resolved based on a hypothesis of cycles of introgression, selection and diversification from non-shattering domesticated rice, importantly in the initial stages in its center of origin in the region of the Yangtze river valley, and subsequently beyond, as domesticated rice spread.
