Molina et al. show that transcription factors of the MYB68 subclade promote cork differentiation in the Arabidopsis root. On the one hand, they activate suberin biosynthesis and polymerizing enzymes; ...

Suberin is a complex biopolymer found in land plants that serves as a natural barrier, regulating water and nutrient uptake while also providing defense against invading pathogens. Structurally, suber...

Single-cell RNA sequencing and spatial transcriptomic approaches reveal major expression changes in outer root cell types when grown in soil versus gel conditions, and also uncover how root tissues communicate and adapt to contrasting soil conditions at single-cell resolution.

Using small nuclear RNA sequencing (snRNA-seq), Miller et al. produced a gene expression census of the maturing Arabidopsis root and, by exploring the development of the suberizing phellem, identify that MYB67 controls phellem cell maturation. This census may serve as resource for engineering future plants with improved stress resilience and carbon capture capacity.

Abstract. The plant lipid polymers cutin and suberin play a critical role in many aspects of plant growth and development, and physiology. The mechanisms o

This Review summarizes recent progress in the understanding of plant apoplastic diffusion barriers, their formation and their function in an environmental context. Open questions and promising researc...

Abstract. The current climate crisis has global impacts and will affect the physiology of plants across every continent. Ensuring resilience of our agricul

Rice roots form apoplastic barriers to limit radial O₂ loss and toxic Fe uptake. In low-O₂ conditions, tight barriers containing enhanced suberin and glycerol esters are formed in the exodermis. In h...

In tomato roots, the exodermis forms a genetically distinct polar lignin cap (PLC) barrier from the Casparian strip. SlSCZ and SlEXO1 repress PLC deposition in inner layers. The PLC cannot fully compe...
