Lipid Rafts to the Rescue! Plants under Fungal Attack Recruit Phospholipase Dδ

Abstract

Accumulation of PLDd-GFP at attempted sites of penetration by powdery mildew in cells of Arabidopsis (left panel; DMSO-treated control) is drastically reduced upon exocytosis-hampering BFA treatment (right panel). Green, PLDd-GFP; magenta, propidium iodide-stained powdery mildew; arrowheads, attempted fungal penetration sites; DMSO, dimethylsulfoxide; BFA, brefeldin A; scale bars = 20 mm.

Biological and Cellular Functions of the Microdomain-Associated FWL/CNR Protein Family in Plants

“…They also control intercellular communications: a specific population of microdomains such as those enriched in the cell-signaling regulator tetraspanin are closely associated with plasmodesmata [15][16][17]. Microdomains control plant response to microbial inoculations including fungal and viral infections [18][19][20][21][22][23][24]. In the legume model Medicago truncatula, the subcellular localization of the microdomain-associated protein FLOTILLIN2 (FLOT2) depends on the recognition of the symbiotic bacteria Sinorhizobium meliloti [25,26].…”
