Public Abstract	Nitrogen-fixation is often the limiting factor for plant growth and crop yield, because nodulation is hindered by inefficient interactions between Rhizobial bacteria and plants. This technology uses tRNA-derived small RNAs to increase root hair curling and nodule number in legumes. Through gene editing of plants with the tRNA-derived small RNAs, the number of productive Rhizobial infections is dramatically increased. Genetic engineering of plants to promote nodulation has applications in enhancing nitrogen-fixation in legumes and in extending nitrogen fixation capabilities to non-legumes. Advantages: -Improved nitrogen fixation -Lower cost of inputs Potential Applications: -Engineering plants to improve nitrogen fixation
