Publication number: 20230062568Abstract: The present disclosure provides consortia of microbes that are functionally optimized for nitrogen fixation and deliver such to plants in a targeted, efficient, and environmentally sustainable manner. The microbes within the consortium differ in nutrient utilization, temporal occupation, oxygen adaptability, and/or spatial occupation, which enables the microbes to deliver nitrogen to a cereal plant in a spatially targeted (e.g. rhizospheric) and temporally targeted (e.g. during advantageous stages of plant's life cycle) manner. The present disclosure also provides methods of creating a synthetic composition of microbes and methods of using compositions of microbes to fix atmospheric nitrogen and deliver such to a crop.Type: ApplicationFiled: January 12, 2021Publication date: March 2, 2023Inventors: Karsten TEMME, Neal SHAH, Bilge OZAYDIN, Sarah BLOCH, Alvin TAMSIR, Daniel FULOP

Publication number: 20220396530Abstract: The present disclosure provides non-intergeneric remodeled microbes that are able to fix atmospheric nitrogen and deliver such to plants in a targeted, efficient, and environmentally sustainable manner. The utilization of the taught microbial products will enable farmers to realize more productive and predictable crop yields without the nutrient degradation, leaching, or toxic runoff associated with traditional synthetically derived nitrogen fertilizer, by mitigating or eliminating the need for exogenous nitrogen-containing fertilizers. The remodeled microbes have unique colonization and nitrogen fixation abilities, which enable the microbes to deliver nitrogen to a cereal plant in a spatially targeted (e.g. rhizospheric) and temporally targeted (e.g. during advantageous stages of plants life cycle) manner. The microbes are able to replace the standard agricultural practice of sidedressing and enable a more environmentally sustainable form of farming.Type: ApplicationFiled: July 11, 2019Publication date: December 15, 2022Inventors: Alvin TAMSIR, Sarah BLOCH, Mark REISINGER, Ernest SANDERS, Richard BROGLIE, Rosemary CLARK, Karsten TEMME

Publication number: 20220127627Abstract: The present disclosure provides guided microbial remodeling (GMR) methods for the rational improvement of plant-associated microbes to perform plant-beneficial functions. The GMR methods described herein allow for non-intergeneric genetic optimization of key regulatory networks within the microbes, which improve plant-beneficial functions over wild-type microbes but don't have the risks associated with transgenic approaches (e.g., unpredictable gene function, public and regulatory concerns, etc.). The present disclosure also provides remodeled microbes and compositions thereof. The utilization of remodeled microbes and compositions thereof will enable farmers to realize more productive and predictable crop yields without the nutrient degradation, leaching, or toxic runoff associated with traditional synthetically derived fertilizers.Type: ApplicationFiled: June 27, 2019Publication date: April 28, 2022Inventors: Sarah BLOCH, Karsten TEMME, Alvin TAMSIR, Douglas HIGGINS, Austin DAVIS-RICHARDSON, Rosemary CLARK, Shayin GOTTLIEB
