Informative here meaning that you can deduce something about a plant's condition from faint sounds emitted by it. It's not implying that the plants use those sounds for the purpose of transmitting information. From the article:
"These results demonstrate the potential in studying plant bioacoustics, suggest that plant acoustic emissions may play an important role in ecology and evolution, and may have direct implications for plant monitoring in agriculture"
To me even the "suggests..." part is wild overselling. IMO this should have been in such a high impact journal only if they had actually succeeded in demonstrating the ecological relevance, by showing that the sounds are detected and acted upon by other organisms.
