the researchers recorded both healthy and stressed tomato and tobacco plants using microphones. They conducted experiments in a soundproof chamber and later in a greenhouse with background noise. The plants were stressed in two ways, by withholding water for several days and by cutting their stems. The team then trained a machine learning algorithm to distinguish between healthy plants, dehydrated plants, and cut plants.

I thought they found this over a decade ago?
I think the thing from a decade ago was about them emitting chemical messages through transpiration. Nova did a piece where transpiration and the fungal network in the soil were reconsidered as a whole communication system. I recall it was popularized using the same "scream" terminology in pop-sci rags.
Nah, it was the same thing, just 8 years ago I guess. This is an article from after I must have caught the paper: https://www.smithsonianmag.com/smart-news/scientists-record-stressed-out-plants-emitting-ultrasonic-squeals-180973716/
Research has to be repeatable
Now it's reproducible bullshit.
