Pathways of Protein Secretion in Prokaryotes and Eukaryotes: Molecular Mechanisms, Biological Functions, and Therapeutic Opportunities

MedComm, Volume 7, Issue 6, June 2026.
This graphical abstract delineates noncanonical protein secretion systems across eukaryotes and prokaryotes. Eukaryotic UcPS covers four ER–Golgi bypass pathways, enabling rapid leaderless protein export via direct transmembrane translocation or vesicle‐mediated release.

A New Species of Arthropteris From Samoa

New Zealand Journal of Botany, Volume 64, Issue 2, June 2026.
A new species, Arthropteris samoensis (Arthropteridaceae), recorded from the Samoan islands of Upolu and Savai‘i, is described and illustrated. In Samoa, the new species is distinguished from Arthropteris palisotii s.l. by its smaller stature and more delicate texture (laminae mostly < 3 cm wide vs.

The relative roles of in situ diversification and lineage dispersal underlying diversity patterns at the assemblage level

Oikos, Volume 2026, Issue 6, June 2026.
Speciation, extinction, and dispersal are the historical processes influencing the spatial distribution of lineages and strongly influence diversity patterns. Here, we apply a recently developed methodological approach to quantify the relative legacies in situ diversification history (i.e.

Under the Cover of Darkness: A Transcriptomic Exploration of Clubroot During the Night

Plant Direct, Volume 10, Issue 6, June 2026.
ABSTRACT Plasmodiophora brassicae (Phytomyxea, Rhizaria) is the etiological agent of clubroot disease, one of the most important diseases of Brassicaceae crops. Alteration of metabolism and hormone homeostasis leads to the formation of tumor‐like galls in the roots of affected plants.

Structural basis for dimerization, catalytic regulation, and substrate selectivity of the chloroplast S9D CGEP protease in Arabidopsis thaliana

Protein Science, Volume 35, Issue 6, June 2026.
Abstract S9 proteases are widely distributed across the tree‐of‐life and play essential roles in protein processing. However, the structural and mechanistic basis for protease activity in the S9D subfamily, restricted to photosynthetic eukaryotes (e.g., plants), cyanobacteria, proteobacteria and flavobacteria, is unknown. Here, we report the first high‐
