...archer Kazunari Nozue, with colleagues from the University of California, Davis, and the University of Lausanne, Switzerland, found that the shoots of arabidopsis seedlings show a spurt of growth once a day. They claimed that the timing of that growth spurt is controlled by both the plant's internal clock and it...New Mechanism for Nutrient Uptake Discovered
... Plants import nitrogen in the form of ammonium from the soil. The researchers found that the end portion, or so-called C-terminus, of the protein arabidopsis ammonium transporter AtAMT1;1, located at the surface of the cell membrane, acts as a switch. "The terminus is an arm-like feature that physical...Engineering Nutrient-Rich Plants Made For Feasible By New Findings
