In the present study, ectopic expression of <i>TOR<\/i> gene of <i><i>Arabidopsis<\/i> thaliana<\/i> in a widely cultivated <i>indica<\/i> rice resulted in enhanced plant growth under water-limiting conditions conferring agronomically important water-use efficiency (WUE) trait. The <i>AtTOR<\/i> high expression lines of rice exhibited profuse tillering, increased panicle length, increased plant height, high photosynthetic efficiency, chlorophyll content and low \u2206<sup>13 <\/sup>C. \u0394<sup>13 <\/sup>C, which is inversely related to high WUE, was as low as 17\u2030 in two <i>AtTOR<\/i> high expression lines. These lines were also insensitive to the ABA-mediated inhibition of seed germination. The significant upregulation of 15 stress-specific genes in high expression lines <i>indica <\/i>tes their contribution to abiotic stress tolerance. The constitutive expression of <i>AtTOR<\/i> is also associated with significant transcriptional upregulation of putative TOR complex-1 components, <i>Os <i>Raptor<\/i><\/i> and <i>OsLST8<\/i>. Glucose-mediated transcriptional activation of <i>AtTOR<\/i> gene enhanced lateral root formation. Taken together, our findings <i>indica <\/i>te that <i>TOR<\/i>, in addition to its multiple cellular functions, also plays an important role in response to abiotic stress and potentially enhances WUE and yield related attributes.<\/p>\n<p><!-- Link: <a href=\"http:\/\/www.nature.com\/articles\/srep42835\">http:\/\/www.nature.com\/articles\/srep42835<\/a> --><\/p>\n","protected":false},"excerpt":{"rendered":"<p>How plants are teaching us about TOR proteins and their impacts on the pathways.
