High-resolution study of a star-forming cluster in the Cep-A HW2 region

open access: yes, 2007
Due to its relatively small distance (725 pc), the Cepheus A East star-forming region is an ideal laboratory to study massive star formation processes.

Development of the HTRF assay to evaluate the auxin‐induced binding between TIR1 and IAA7

open access: yesNew Phytologist, Volume 250, Issue 5, Page 3475-3485, June 2026.
Summary Auxin plays diverse roles in plant growth and development, including sensing environmental changes. Quantifying the interaction between auxin coreceptors provides the molecular basis for cells to sense and adapt to environmental cues. Although several assays are available, a more high‐throughput method is necessary to efficiently evaluate the ...

The structure of intact and active Photosystem II from Arabidopsis thaliana at 2.44 Å resolution

open access: yesNew Phytologist, Volume 250, Issue 5, Page 3014-3025, June 2026.
Summary Photosystem II (PS II) is a large membrane‐bound protein complex that catalyses light‐driven water oxidation in plants and cyanobacteria. The structure of PS II is well studied in cyanobacteria; however, there are very few PS II structures from plants.

Disentangling phase transitions and critical points in the proton–neutron interacting boson model by catastrophe theory

open access: yesPhysics Letters B, 2014
We introduce the basic concepts of catastrophe theory needed to derive analytically the phase diagram of the proton–neutron interacting boson model (IBM-2). Previous studies [1–3] were based on numerical solutions.

From pathogens to partners: temporal and biogeographical patterns in fungal associations of alien trees

open access: yesNew Phytologist, Volume 250, Issue 5, Page 3381-3395, June 2026.
Summary Alien trees reshape belowground fungal communities, but the factors governing the balance between mutualists and pathogens remain unclear. We tested whether residence time, mycorrhizal type, and biogeographical origin shape this balance, and whether alien stands differ from native vegetation. We sampled soils beneath 73 alien tree species in 48
