A PDLP-NHL3 complex integrates plasmodesmal immune signaling cascades

The paper identifies a PDLP-NHL3 complex that integrates multiple immune signaling pathways to trigger plasmodesmal closure in response to microbial elicitors and stress.

Comparative phyloproteomics identifies conserved plasmodesmal proteins

The paper identifies conserved plasmodesmal proteins through comparative proteomics across Arabidopsis and moss, revealing core components like β-1,3-glucanases and tetraspanins.

The Hyaloperanospora arabidopsidis effector HaRxL77 is hypermobile between cells and manipulates host defence

This study identifies HaRxL77, an effector from the plant pathogen Hpa, as hypermobile between cells and manipulates host defence by modifying plasmodesmata permeability and suppressing ROS bursts.

Colletotrichum higginsianum effectors exhibit cell to cell hypermobility in plant tissues and modulate intercellular connectivity amongst a variety of cellular processes

The paper identifies cell-to-cell mobile effectors from the fungal pathogen Colletotrichum higginsianum and shows some modulate plant processes and plasmodesmal aperture.

A bootstrap approach is a superior statistical method for the comparison of cell-to-cell movement data

The paper compares statistical methods for analyzing cell-to-cell movement data and finds the bootstrap method outperforms the Mann-Whitney-Wilcoxon test in controlling false positive rates.

Range size dynamics can explain why evolutionarily age and diversification rate correlate with contemporary extinction risk in plants

The paper shows that younger and faster-diversifying plant genera have higher extinction risk, and range size dynamics may explain these patterns across the Tree of Life.
