Neutral interactions among non‐native plants are common

New Phytologist, Volume 252, Issue 1, Page 292-309, October 2026.
Global distribution of studies and overall effect of co‐invasion for all metrics of non‐native plant performance combined. Summary Globalization has accelerated the establishment of non‐native plant species, increasing the prevalence of multispecies co‐invasions; yet interactions among co‐invaders remain poorly understood.

The cold case of state transition 7 (stt7) mutants of Chlamydomonas reinhardtii, solved by whole‐genome sequencing

New Phytologist, Volume 252, Issue 1, Page 145-162, October 2026.
Long‐read whole‐genome sequencing revealed extensive chromosomal rearrangements and aneuploidy in a widely used Chlamydomonas reinhardtii stt7‐1 mutant. The STT7 gene (shown in red) was found to be split between two rearranged chromosomes, providing a molecular explanation for the long‐standing failure of this mutant in genetic crosses.

TipQuant: a robust algorithm for quantitative analysis of spatiotemporally dynamic activities in tip‐growing cells

New Phytologist, Volume 252, Issue 2, Page 926-935, October 2026.
Tip Quantification enables quantitative analyses over versatile selections of regions of interest. Summary Cell polarity and tip growth rely on the dynamic spatial organization of signaling and structural components. Quantitative characterization of these spatiotemporal dynamics is critical for understanding polarized cell growth, yet manual ...

Exploring the molecular basis of microphthalmia and anophthalmia: Insights from an Egyptian cohort

Purpose The aim of this study was to gain insight into the molecular spectrum of anophthalmia and microphthalmia (A/M) in the Egyptian population. Methods We studied a cohort of 34 patients from 31 unrelated families affected by the A/M spectrum.

AUXIN RESPONSE FACTORs: from transcription factors to auxin effectors

New Phytologist, Volume 252, Issue 2, Page 607-613, October 2026.
Molecular evolution of AUXIN RESPONSE FACTOR (ARF) effector function. Summary Signalling pathways have originated and diversified extensively during evolution. Using AUXIN RESPONSE FACTORs (ARFs) as a model, we examine how a plant signalling system evolved through the co‐option of pre‐existing transcriptional regulators, a principle well established in

Plant genotypic diversity and defoliation jointly shape root exudation, fungal communities, and carbon and nitrogen cycling

New Phytologist, Volume 252, Issue 1, Page 324-339, October 2026.
Experimental design. Summary Intraspecific plant diversity is a major component of community diversity, yet its role in shaping plant–microbial interactions and soil functioning remains poorly understood. In particular, plant genotypic diversity may modulate ecosystem responses to defoliation, a key driver of ecosystem processes in grazed systems.
