Scientists engineer shortcut for photosynthetic glitch, boost crop growth by 40 percent

Pyhs.org | January 03, 2019

Plants convert sunlight into energy through photosynthesis; however, most crops on the planet are plagued by a photosynthetic glitch, and to deal with it, evolved an energy-expensive process called photorespiration that drastically suppresses their yield potential. Researchers from the University of Illinois and U.S. Department of Agriculture Agricultural Research Service report in the journal Science that crops engineered with a photorespiratory shortcut are 40 percent more productive in real-world agronomic conditions.
"We could feed up to 200 million additional people with the calories lost to photorespiration in the Midwestern U.S. each year," said principal investigator Donald Ort, the Robert Emerson Professor of Plant Science and Crop Sciences at Illinois' Carl R. Woese Institute for Genomic Biology. "Reclaiming even a portion of these calories across the world would go a long way to meeting the 21st Century's rapidly expanding food demands—driven by population growth and more affluent high-calorie diets."
This landmark study is part of Realizing Increased Photosynthetic Efficiency (RIPE), an international research project that is engineering crops to photosynthesize more efficiently to sustainably increase worldwide food productivity with support from the Bill & Melinda Gates Foundation, the Foundation for Food and Agriculture Research (FFAR), and the U.K. Government's Department for International Development (DFID).

Magenta Therapeutics, Inc. and Dianthus Therapeutics, Inc. a privately-held, clinical-stage biotechnology company dedicated to advancing the next generation of antibody complement therapeutics, announced today that they have entered into a definitive merger agreement to combine the companies in an all-stock transaction. The combined company will focus on advancing Dianthus’ pipeline of next-generation complement inhibitors, including DNTH103 currently in a Phase 1 clinical trial. Upon completion of the merger, the combined company is expected to operate under the name Dianthus Therapeutics, Inc. and trade on the Nasdaq under the ticker symbol “DNTH”. In support of the merger, Dianthus has secured commitments for a $70 million private investment in its common stock and pre-funded warrants from a syndicate of healthcare investors led by Fidelity Management & Research Company, Catalio Capital Management, 5AM Ventures, Avidity Partners, Wedbush Healthcare Partners and founding investors Fairmount, Tellus BioVentures and Venrock Healthcare Capital Partners, that is expected to close immediately prior to completion of the merger. With the cash expected from both companies at closing and the proceeds of the concurrent private financing, the combined company is expected to have approximately $180 million of cash or cash equivalents immediately post-closing. The cash resources are intended to be used to advance Dianthus’ pipeline through multiple clinical data catalysts and is expected to fund operations into mid-2026. The merger and related financing are expected to close in the third quarter of 2023. “I’m delighted to announce this planned merger with Magenta, which comes at a pivotal moment in the evolution of our company as we advance our pipeline of next-generation complement therapeutics for people living with severe autoimmune diseases,” said Marino Garcia, President and Chief Executive Officer of Dianthus Therapeutics. “Gaining access to the public capital markets can enhance our financial strength and fuel our growth strategy, enabling us to unlock the full potential of our pipeline, including our plans to address multiple autoimmune disorders with our clinical-stage active C1s inhibitor, DNTH103.” “After a thorough exploration of our strategic alternatives, management and our Board of Directors believe the transaction with Dianthus Therapeutics will culminate in a successful outcome for our stockholders,” said Steve Mahoney, President, Chief Financial and Operating Officer of Magenta. “Dianthus has made rapid progress in developing and advancing DNTH103 into the clinic where it has the potential to be a transformative classical pathway inhibitor for severe autoimmune diseases. We are extremely grateful to our current and former employees who contributed to Magenta’s efforts to develop its programs and we now look forward to the combined company’s advancement on opportunities for value creation for patients.” Magenta previously announced a comprehensive review of strategic alternatives in February 2023 and has since completed winding down a majority of its activities and costs associated with its research and development initiatives, including the termination of its lease and the sale of key assets. erving as co-financial adviser and Goodwin Procter LLP is serving as legal counsel to Magenta Therapeutics. Jefferies, Evercore ISI, Guggenheim Securities and Raymond James are serving as the placement agents to Dianthus Therapeutics, and Gibson, Dunn & Crutcher LLP is serving as legal counsel to Dianthus Therapeutics.
