A bottom-up model of wall mechanics in stomatal guard cells reveals how wall composition and structure modulate the biomechanical properties that enable stomatal movements.
Rice is a staple food worldwide and is eaten by billions of people on a daily basis. Still, high levels of toxic arsenic and cadmium in the grain have raised severe concerns about its safety for human consumption. Gui and colleagues used genetic engineering to combat this problem.
By analysing herbarium specimens, scientists found new plants that take rare earth elements from the ground, which could help get more of these important metals in a more sustainable way.
Scientists used DNA to track how a group of tropical plants travelled across continents over millions of years and found that they were able to spread because they attracted a variety of animals to eat their fruits and excrete their seeds.
