A tribute to Graziella Berta (1948–2024): research milestones and highlights

Graziella Berta, a well-known mycorrhiza researcher, passed away in her home in Torino (Italy) on March 2nd, 2024, at the age of 75. We were both fortunate to know Graziella personally and to greatly appreciate her professionally, by working closely with her in the same research group in Alessandria (GL) or through many collaborative projects over the years (VGP). Here, we recall some of the milestones in her research and particularly the important contribution she has made to knowledge about plant interactions with mycorrhizal fungi and beneficial rhizosphere bacteria.
