Synaptotagmin-mediated plasma membrane homeostasis is required to recruit the endocytic machinery during cold stress

This study shows that SYT1 and SYT3 are essential for maintaining endocytosis during cold stress in Arabidopsis by preserving membrane composition and TPC subunit association.

Spatially-restricted metabolic delivery of auxin for selective adventitious root induction

The paper identifies HYS as a shoot-specific proauxin that releases MCPA to induce adventitious roots, offering a framework for tissue-specific auxin delivery.

Ribosome biogenesis factor AtRRB1 confers pollen heat stress tolerance in Arabidopsis

This study identifies AtRRB1 as a ribosome biogenesis factor that enhances heat stress tolerance in Arabidopsis pollen by supporting protein synthesis and ER function during microspore development.

Synaptotagmins Maintain Diacylglycerol Homeostasis at Endoplasmic Reticulum-Plasma Membrane Contact Sites during Abiotic Stress

The paper shows that synaptotagmins maintain diacylglycerol homeostasis at ER-PM contact sites during abiotic stress by preventing its detrimental accumulation at the plasma membrane.
