A drought stress‐induced MYB transcription factor regulates pavement cell shape in leaves of European aspen (Populus tremula)

open access: yesNew Phytologist, Volume 251, Issue 5, Page 2688-2705, September 2026.
MYB305a promoter expression increases in pavement cells as they grow and acquire their complex shape. Summary Leaf pavement cells of many plant species develop jigsaw puzzle‐like shapes in which neighboring cells interdigitate, providing an ideal model for the study of cell shape regulation.

Systemic acquired resistance: an emerging role for jasmonates in local signal biogenesis, translocation and distal signal decoding

open access: yesNew Phytologist, Volume 251, Issue 6, Page 3142-3158, September 2026.
Jasmonate signalling underpins establishment of plant systemic acquired resistance (SAR). Activation of the hypersensitive response (HR) not only contains the pathogen but establishes broad spectrum resistance in unchallenged leaves. The strong burst of reactive oxygen/nitrogen species initiating the HR results in lipid peroxidation (illustrated by ...

NbRD21 protease controls receptor kinase homeostasis in Nicotiana benthamiana

open access: yesNew Phytologist, Volume 251, Issue 5, Page 2741-2752, September 2026.
Proteomic analysis revealed that receptor kinases (red) accumulate higher in rd21 knockout Nicotiana benthamiana plants. Summary RD21‐like proteases are papain‐like cysteine proteases with a C‐terminal granulin domain that are abundant and ubiquitous in angiosperms and have often been implicated in immunity.

Partial mycoheterotrophy: a common strategy in arbuscular mycorrhizal plants?

open access: yesNew Phytologist, Volume 251, Issue 6, Page 3096-3110, September 2026.
Proposed autotrophy to mycoheterotrophy continuum among arbuscular mycorrhizal plants. Summary The vast majority of land plants transfer part of the organic carbon they produce by photosynthesis to arbuscular mycorrhizal (AM) fungi inside their root cells; the fungi in turn help plants to take up nutrients and water from the soil.
