Research Abstract |
Silicon (Si) is a beneficial element for plant growth, which helps plants to overcome multiple stresses. In this project, we have identified several transporters involved in Si uptake and distribution. Lsi1 and Lsi2 identified from rice are expressed in the roots and polarly localized at the exodermis and endodermis. These transporters are important for Si uptake by the roots. Lsi6 is localized at the xylem parenchyma of leaf and node I and responsible for distribution of Si. We also identified similar transporters from maize and pumpkin. We found that they have different expression pattern and localization from rice.
