The root tip of the model plant Arabidopsis thaliana senses the environment and adjusts root growth in response. Labeled in red are three layers of cells on the root’s surface to the depth of 20 micrometers. Green indicates gene activity associated with lengthening the root. This image, from the lab of Wolfgang Busch, and others like it allow researchers to observe plants under extreme environmental conditions, with the aim of growing plants that can withstand climate change-induced stress.
