Fig. 1. LTP1 enhanced cowpea resistance against Botrytis cinerea. A, Symptoms induced by B. cinerea in cowpea leaves overexpressing LTP1. Lesions were observed at 48 h postinoculation (hpi) of B. cinerea. Scale bar = 1.5 cm.

Plant lipid transfer proteins (LTPs), belonging to the pathogenesis-related protein 14 family, participate in plant immune response to biotic stress. Jie Ji et al. analyzed the role of LTP1 in plant resistance to eukaryotic pathogens: https://doi.org/10.1094/MPMI-04-25-0041-SC

The trans‐Golgi network adaptor protein 4 complex contributes to basal defense and immunity mediated through plasma membrane and intracellular immune receptors The trans-Golgi network adaptor protein 4 (AP4) complex, which mediates protein sorting to the plant vacuole, is essential for broad immune responses including basal defense as well as pattern- and e...

Quantification of cell‐type‐specific plasmodesmata distribution in Arabidopsis roots reveals spatial and patterning dynamics Plasmodesmata are cytoplasmic channels essential for intercellular communication in plants; yet their organ-scale distribution and regulation remain poorly understood. Here, we establish a quantitati...

⚙️Technical Advance

How are plasmodesmata distributed across tissues? 🌱

Davis et al. developed a 3D quantitative imaging pipeline to map pit fields at cell-type resolution in Arabidopsis roots.
They’re developmentally reallocated and spatially patterned by BR signaling.

Plants monitor the integrity of their barrier by sensing gas diffusion - Nature A study using Arabidopsis shows that plants can monitor the integrity of their outer barriers by sensing gas diffusion, enabling them to initiate wound repair to prevent water loss and pathogen entry.

Plants can sense when their barrier is injured—and repair it! 🌱
This stunning work, led by Hiroyuki Iida, shows that wounding is sensed through the diffusion of two gases: ethylene and oxygen.
I had the pleasure of contributing and see this project grow.

The mechanical properties of Arabidopsis thaliana roots adapt dynamically during development and to stress Brillouin microscopy reveals in vivo dynamics of mechanical properties during plant development and response to stress.

Our work now on its final version. We mapped the mechanical properties of roots at tissue and single cell levels using Brillouin microscopy and molecular rotors. Additional mutants and stress measurements from what we previously showed in the preprint are included.

I am very excited to share my simultaneous triple staining method for monocot roots. This method is not only faster but also utilizes a smaller volume of stain than traditional methods and minimizes mechanical tissue damage.

A plant ‘vaccine’ takes on corn rootworm, a fearsome pest Inoculating soil with pink microbes could help reduce the use of toxic insecticides.

Damage from corn rootworm costs an excess of $1 billion each year in the United States alone. Man P. Huynh et al. may have found a solution: doi.org/10.1094/PBIO...
