Seeing Plants in Three Dimensions

Scientists are taking a new look at the inner workings of plants by imaging and modeling them in three dimensions.

“We’ve realized tremendous advances in technology for 3-D imaging of leaves,” said Tom Buckley, assistant professor of plant sciences at UC Davis.

Recent developments are summarized in an article in Trends in Plant Sciences, which sprang from a 2017 workshop at the University of Sydney organized by Buckley and Professor Margaret Barbour, University of Sydney.

Just like humans, plants have an immune system that helps them fight off infections. Plant immunity has some important differences: they don’t make antibodies and can’t fight off the same bug more quickly months or years later. However, plant cells can identify pathogens and react to them, often by producing a burst of reactive oxygen which is toxic to bacteria or fungi. Cells around an infected site will go into programmed cell death to seal off the disease.
