Scientists Clone Rare Gene to Enhance Rice Grain Yield
September 23, 2015| |
Scientists from the Chinese Academy of Agricultural Sciences and Chinese Academy of Sciences reported that an important gene GS2 was successfully isolated and cloned from a local Chinese rice variety Baodali from Zhejiang province. The gene GS2 could significantly enhance the yield of super rice. Their findings are published in the latest issue of Molecular Plant journal.
The research article discusses the cloning and characterization of dominant quantitative trait loci (QTL) that codes for a transcriptional regulator Growth-Regulating Factor 4 (OsGRF4). GS2 is located in the nucleus and may serve as transcription activator. Increase in GS2 expression leads to larger cells and increased numbers of cells, causing improved grain weight and yield.
