| 摘要 |
Based on our identification of silicon influx and efflux transporter genes in plants known to take up silicon efficiently including wheat, horsetail, oat, sorghum, and barley, the present invention features polynucleotides encoding silicon transporters; vectors, cells, and plants including such polynucleotides, and methods for making such plants. The invention also features silicon transporter polypeptides and fragments thereof. Plants expressing heterologous silicon transporters may exhibit both increased silicon uptake and increased resistance to biotic and abiotic stresses. In particular, plants such as soybean expressing silicon transporters may exhibit increased resistance to pathogens such as rust.
