| Summary, etc. | The rising heavy metal contamination of soils imposes toxic impacts on plants as well as other life forms. One such highly toxic and carcinogenic heavy metal is hexavalent chromium [Cr(VI)] that has been reported to prominently retard the plant growth. The present study investigated the potential of silicon (Si, 10 µM)to alleviate the toxicity of Cr(VI)(25 µM)on roots of wheat (Triticum aestivum L.)seedlings. Application of Si to Cr(VI)-stressed wheat seedlings improved their overall growth parameters. This study also reveal the involvement of two phytohormones, namely auxin and cytokinin involving their crosstalk for Si-mediated mitigation of the toxic impacts of Cr(VI)in wheat seedlings. The application of cytokinin alone to wheat seedlings under Cr(VI)stress reduced the intensity of toxic effects of Cr(VI). In combination with Si, cytokinin application to Cr(VI)-stressed wheat seedlings significantly minimized the decrease induced by Cr(VI)in different parameters such as root-shoot length (10.8 and 13 percent), root-shoot fresh mass (11.3 and 10.1 percent), and total chlorophyll and carotenoid content (13.4 and 6.8 percent)with respect to control. This treatment also maintained the regulation of proline metabolism (proline content, P5CS and ProDH activity), ascorbate-glutathione (AsA-GSH)cycle and nutrient homeostasis. The protective effect of Si and cytokinin against Cr(VI)stress was minimized upon supplementation of an inhibitor of polar auxin transport- 2,3,5-triiodobenzoic acid (TIBA)which suggested a potential involvement of auxin in Si and cytokinin-mediated mitigation of Cr(VI)toxicity. The exogenous addition of a natural auxin - indole-3-acetic acid (IAA)confirmed auxin is an active member of a signaling cascade along with cytokinin that aids in Si-mediated Cr(VI)toxicity alleviation as IAA application reversed the negative impacts of TIBA on wheat roots treated with Cr(VI), cytokinin and Si. The results of this research are also confirmed by the gene expression analysis conducted for nutrient transporters (Lsi1, CCaMK, MHX, SULT1 and ZIP1)and enzymes involved in the AsA-GSH cycle (APX, GR, DHAR and MDHAR). The overall results of this research indicate towards possible induction of a crosstalk between cytokinin and IAA upon Si supplementation which in turn stimulates physiological, biochemical and molecular changes to exhibit protective effects against Cr(VI)stress. Further, the information obtained suggests probable employment of Si, cytokinin and IAA alone or combined in agriculture to maintain plant productivity under Cr(VI)stress and data regarding expression of key genes can be used to develop new crop varieties with enhanced resistance against Cr(VI)stress together with its reduced load in seedlings. |
