🌱🔬 We’ve uncovered a link between pectin and plasmodesmata! 🍎🧬 Changes in the cell wall’s pectin composition might be opening up larger pores, altering nutrient flow between cells. Could pectin be one key element to plasmodesmata regulation? 🧐 (5/6)

🌱🔬 Meet our open sesame mutant that breaks the rules! 🌱 Larger plasmodesmata apertures in this mutant coincide with bidirectional transport, defying the usual one-way flow. 🚪✨ (4/6)

🌱🔬 As roots mature, plasmodesmatal transport shifts from a two-way street to a one-way road! 🌊 We found that water flow drives symplastic transport from outer to inner root layers, but the mystery of how directionality happens remains. (3/6)

[Jacquier Léa @JacquierLea]

🌱🔬 We confirmed that cell-to-cell transport through plasmodesmata remains active even in mature plant roots! 💡 Despite endodermal barriers like Casparian strips and suberin, the symplastic pathway stays open for molecules to move freely. (2/6)

Very happy to share our latest contribution on endodermal suberin! Suberin plasticity to development and exogenous cues is regulated by a set of MYB transcription factors. https://t.co/JoK8PccHCl

Happy to share our first preprint with @vnayshuklaa et al. Our new contribution to suberin plasticity in the endodermis and the role of 4 MYB TFs in this regulation : https://t.co/sWfxkj2vOK
