Description
Sakharam Waghmare and co-authors map what a plant's essential shipping protein actually ships, in a 2024 study. The protein, SYP132, is a SNARE that fuses cargo vesicles with the cell surface in Arabidopsis. Unlike its two cousins, it is indispensable: plants cannot grow or survive without it. It was known to recycle a proton pump and a water channel and to export a defense protein. The team tagged proteins in the leaf's outer fluid to catch its native cargo.
SYP132 keeps a basal stream of secretion flowing, and boosting it reshaped hormone-linked defense cargo, including three classic pathogenesis-related proteins. Crippling it also choked defense secretion when a bacterial pathogen attacked. The authors conclude the protein underpins everyday secretion and basal immunity alike, a quiet logistics hub for the leaf's dealings with the world.
