As a traditional cuisine in Japan and other Asian countries, rice has a long history of use. Three gene alterations that make the seeds (i.e. rice grains) less likely to fall off the plant, according to the findings of a recent study by an international research cooperation, may be responsible for the development of cultivated rice from wild rice plants.
Three mutations, when combined, result in a higher yield of rice.
When our forefathers discovered and began cultivating rice plants that do not readily shed their seeds, they paved the road for long-term rice production stability. Future advances in rice seed fall (i.e. making the crop simpler to thresh) and creation of high-yield rice cultivars where every grain may be gathered, decreasing wastage, are anticipated to arise from these study findings.
To make this discovery, a team of researchers from universities around the world worked together, including those from the Graduate School of Agriculture at Kobe University, Japan's National Institute of Genetics, the Universities of London, Warwick, and Yezin in Myanmar, as well as researchers from CAREDIA in Cambodia.
PNAS (Proceedings of the National Academy of Sciences) released these results on the 23rd of June in an online journal (JST).
The Background of the Study
In the United States, Asian rice is known to as Oryza Sativa, which is extensively farmed and eaten. The wild rice weed Oryza rufipogon is believed to have been the source of the plant. Ancient hunter-gatherers are said to have started cultivating rice by selecting individual wild rice plants with the right qualities. It is possible for wild rice plants to effectively spread their seeds via a process known as seed cracking. Although this seed breaking must be avoided when farming rice, it must be controlled in order to provide a steady harvest There was speculation in 2006 that a mutation in the sh4 gene, which is required for the beginning of seed breaking in plants such as rice, allowed rice to be cultivated. Researchers now believe that the sh4 mutation alone is not sufficient to prevent seed shattering loss, and this suggests that other gene alterations are also at play. This research brings together experts in plant genetics, archaeobotany, and structural mechanics to examine how rice was first grown and how yields increased through time.
