Mutations at the dimeric or interdimeric interfaces enhance pathogen-induced cell death and immunity in Nicotiana benthamiana. The cryo-electron microscopy structures unexpectedly show inositol hexakisphosphate (IP6) or pentakisphosphate (IP5) bound to the inner surface of the C-terminal leucine-rich ...
(D) Transmission electron micrograph of a BY-2 cell transiently-expressing GFP-APX. Individual peroxisomes indicated with solid arrowheads were identified by their single boundary membrane. Note the presence of numerous homo- and heterotypic aggregates of plastids, mitochondria, and peroxisomes within ...
(C) Scanning electron micrograph of Xoo cells in the xylem vessel of a rice leaf. (D) Close-up of Xoo-infected rice leaf. Bacterial cells fill the xylem vessels and ooze out at hydathodes, forming beads or strands of exudate on the leaf surface, a characteristic sign of the disease. ...
This indicates that the OMVs are derived from the outer membrane and more interestingly only contain mature LPS whilst the whole cell preparations also contain intermediates of the LPS biosynthesis. Figure 1 Electron micrgraphes of Xcc cell and OMV preparations. (A) Electron micrograph of 1% (w/...
