Key Points

Drought is written into trees, appearing as narrow bands in their annual growth rings. But aspen may go farther, creating "functional memories" of previous dry years reflected in the chemistry of their leaves, according to new research by University of Utah biologists.

Plant-bacteria partnership reveals how roots access iron locked in soil

A new study led by Paul Schulze-Lefert from the Max Planck Institute for Plant Breeding Research in Cologne, in collaboration with Ricardo F.H. Giehl at the Leibniz Institute of Plant Genetics and Crop Plant Research in Gatersleben, revealed how Arabidopsis plants adapt their chemical communication with the bacterial root microbiota to maximize the acquisition of bio-unavailable iron from acidic or calcareous soils. The study is now published in Cell.
