Systemic inoculation of peduncle truss resulting in colonization of xylem vessels within the funiculus of a developing tomato seed. (A) Differential-interference-contrast image of xylem vessels leading into the developing seed. (B) Magnification of panel A showing xylem with eGFP-labeled Clavibacter michiganensis subsp. michiganensis colonization. The confocal image was acquired by merging three channels (488 nm, 543 nm, and transmitted light). Scale bars: 50 μm in panel A; 20 μm in panel B.
