Cell walls and their role in the plant root microbiome Plant roots form a microbiome that interacts at the cell wall extracellular matrix before entering the cell. The root primary and accessory walls present a dynamic, cell-type-dependent scaffold that microbes must navigate, using shared cellulose or contrasting chitin motifs and influencing plant gene responses that encode enzymes for cell wall biosynthesis and degradation. We propose that an interface evolves as microbes reach the root tip and interact with host polymers, potentially driving concurrent degradation of root and microbial cells. Knowledge gaps span diffusion, fluid flow, nutrient exchange, and the physics of microbial motion within the wall boundary. Advances in in situ imaging and mathematical modelling can help understand the dynamics of cell walls to design root microbiomes to function in agroecosystems.

Comparative proteomic profiling of receptor kinase signaling reveals key trafficking components enforcing plant stomatal development Proteomic mapping uncovers endocytosis adaptors that drive receptor internalization for robust stomatal development.

Published! From a proteomic atlas of the ERECTA signaling network, we show that receptor kinase endocytosis is essential for proper stomatal patterning. Congrats, Pengfei, @edwardmarcotte.bsky.social, @hhmi-science.bsky.social, @texasscience.bsky.social & co-authors!

Fig. 1.Phylogenetic tree showing the classification of Streptophyta CESA and CSLD sequences. A selection of 6580 Streptophyta sequences containing the GT2 domain and the RING domain in their N-terminus were aligned with MUSCLE, and a maximum likelihood (ML) tree was inferred using Fast-tree. Six phylogenetic classes of CESA proteins from seed plants are labelled based on their Arabidopsis members. The tree is organized to highlight the details of bryophyte, lycophyte, and CGA sequences. The 15 proteins used for complementation studies are indicated by squares (the square for fern class C is hidden as that part of the tree has been collapsed to highlight the details of bryophyte, lycophyte, and CGA CESAs). An alternative representation of the same tree is shown in Supplementary Fig. S1.

During secondary growth, primary protective barriers break, and a new one forms beneath: the phellem.

But what triggers phellem to differentiate and become a functional barrier? Our results show it’s mechanical cues from tissue rupture 🌱
