摘要: Many publications indicated various beneficial effects of the addition silicon (Si) in soil on physiology rice plants. The gene responsible for Si-uptake rice, low Si-influx 1 (Lsi1), was identified and cloned this study. photosynthetic rate (Pn), grain yield, resistance to Cadmium (Cd)-stress wild-type (WT) Lsi1-transgenic Lemont lines under Cd-stress were examined an attempt better understand mechanism associated with Si-addition, Cd-stress, physiology. Si-fertilization significantly reduced Cd-content Cd-stress. effect most significant Lsi1-overexpression transgenic (Lsi1-OE line) high Conversely, Cd lowered plants indicating a interaction between two elements. During grain-filling period, greatly chlorophyll content Pn resulting diminished output. However, Lsi1-OE line higher than either WT or Lsi1-RNAi (Lsi1-RNAi maintained photo-assimilate transportation high yield potential. At harvest, contained more Si less WT, whereas showed opposite result. In general, reduced, while increased, yield rice. no difference yields existed line. This might be due compensation effect generated by It appeared that soil, as well enhancing inhibiting Lsi1 expression Cd-toxicity plants, could affect making alternations these factors plausible approach production improvement.
