Transmission electron micrographs of protein bodies. Leaf sections were infiltrated with a pEAQ-HTZera®-VP2ep and b pEAQ-HTZera®-VP2 and c infiltration medium as a negative control. PBs for both Zera®-VP2ep (a – blue arrows) and Zera®-VP2 (b – pink arrows) were present as electron-dense structures within the cytoplasm of the infiltrated leaves. No similar structures were present in the negative control samples (c). Scale bars: a and b: 0.5 μm; c: 0.2 μm. CW: cell wall, CPT: chloroplast, CYT: cytoplasm, ER: endoplasmic reticulum
