Plant Scientist Highlight: Sue Hartley

A series by Alyssa Preiser Why did you decide to pursue science as you went through college, and what got you particularly interested in plant defense and plant/organism interactions? I was always interested in science. It started as a young kid when I used to collect natural history - animal skulls,…

Opinion: Limits to tree growth and longevity (TIPS)

I think trees are awesome, and I mean that in the truest sense of the word. They dwarf us in height, and when we look at a tree that has lived for hundreds or thousands of years it is impossible not to think of that span in terms of human generations and human history.

Opinion: Rapid responses to abiotic stress (TIPS)

Several recent studies have demonstrated that plants are able to respond to environmental challenges within minutes, through electrical signals, calcium oscillations, hydraulic changes, metabolites such as glutamate, and reactive oxygen species. Kollist et al. review studies of rapid responses that control…

A synthetic oxygen sensing device for plants

Plants can die from a lack of oxygen (hypoxia), which contributes to the devastating losses caused by flooding. Iacopino et al. set out to develop a more specific method for detecting oxygen levels in plants, based on the mammalian Hypoxia Inducible transcription Factor HIF.  HIF is hydroxylated by…
