Evolution of molecular communication in the permanent Azolla symbiosis

open access: yesNew Phytologist, Volume 249, Issue 4, Page 1666-1674, February 2026.
Summary Heritable symbioses exist across eukaryotes with different degrees of intimacy. In most cases, the symbionts are obligate and require inheritance for their survival. On the host side, symbiont retention can facilitate fitness benefits. Only rarely are these symbioses interwoven to the point that host survival relies on the symbiont.

Climate and hybridization shape stomatal trait evolution in Populus

open access: yesNew Phytologist, Volume 249, Issue 2, Page 792-809, January 2026.
Summary Stomata play a critical role in regulating plant responses to climate. Where sister species differ in stomatal traits, interspecific gene flow can influence the evolutionary trajectory of trait variation, with consequences for adaptation. Leveraging six latitudinally distributed contact zones spanning the natural hybrid zone between Populus ...

Physiological roles of lignins – tuning cell wall hygroscopy and biomechanics

open access: yesNew Phytologist, Volume 248, Issue 6, Page 2674-2706, December 2025.
Summary Lignins constitute the second most abundant carbon‐storing biopolymers in the biosphere. These phenolic polymers accumulate in different concentrations, compositions, and localisations within and between cell wall layers and cell types. Lignins were acquired during plant terrestrialisation 450 million years ago, and the diversification of their
