Pectin methylesterase activity is required for RALF1 peptide signalling output

This study shows that pectin methylesterase activity is necessary for RALF1 peptide signaling, as it enables binding to de-methylesterified pectin for FERONIA-dependent perception.

Pectin cell wall remodeling through PLL12 and callose deposition through polar CALS7 are necessary for long-distance phloem transport

This study identifies PLL12 and CALS7 as essential for phloem transport by remodeling pectin and callose in sieve pores, affecting long-distance symplastic transport.

An Arabidopsis root phloem pole cell atlas reveals PINEAPPLE genes as transitioners to autotrophy

The paper generates a single-cell atlas of Arabidopsis root phloem pole cells and identifies PINEAPPLE genes as key regulators in the transition to autotrophy.

Extracellular membrane tubules involved in suberin deposition in plant cell walls

The paper shows that extracellular membrane tubules are associated with suberin lamellae formation in plant cells.

CASP microdomain formation requires cross cell wall stabilization of domains and non-cell autonomous action of LOTR1

The paper shows that LOTR1, an extracellular protease, is required for non-cell-autonomous positioning of Casparian Strip domains in plants, coordinating their formation across neighboring cells.
