Fossil find in California shakes up the natural history of cycad plants
Cycads, a group of gymnosperms which can resemble miniature palm trees (like the popular sago palm houseplant) were long thought to be “living fossils,” a group that had evolved minimally since the time of the dinosaurs. Now, a well-preserved 80-million-year-old pollen cone discovered in California has rewritten scientific understanding of the plants.
Ancestral variation guides future environmental adaptations
The speed of environmental change is very challenging for wild organisms. When exposed to a new environment individual plants and animals can potentially adjust their biology to better cope with new pressures they are exposed to – this is known as phenotypic plasticity.
Rapid plant evolution may make coastal regions more susceptible to flooding and sea level rise, study shows
Evolution has occurred more rapidly than previously thought in the Chesapeake Bay wetlands, which may decrease the chance that coastal marshes can withstand future sea level rise, researchers at the University of Notre Dame and collaborators demonstrated in a recent publication in Science.
‘Extreme’ plants grow faster in the face of stress
When faced with conditions that are too dry, salty, or cold, most plants try to conserve resources. They send out fewer leaves and roots and close up their pores to hold in water. If circumstances don’t improve, they eventually die.
Lighting the tunnel of plant evolution: Scientists explore importance of two-pore channels in plants
Two-pore channels (TPCs) are ancient ion channels present in the cells of both animals and plants.
