I wrote a commentary on Segundo-Ortin & Calvo's paper on #plantsentience. It is open access (there are other commentaries too and more coming): " #Stress : An adaptive problem common to plant and animal science"

Stress: An adaptive problem common to plant and animal science
It is very hard to determine whether plants have “felt states,” but they do have specific states, such as stress, that depend on sensory input from their environment. Plants do not have neurons or brains, but they do have xylem and phloem, as well as many signalling molecules that are dynamically distributed in their bodies, enabling them to produce systemic responses to environmental stimuli. One common topic in plant and animal science that may or may not prove to involve sentience but that does involve the same molecules is stress.
