Fig 3. CEP1 is specifically expressed in leaf cells undergoing cell death that surround the chlorotic lesions.
A. The white area (black asterisk *) indicates a chlorotic lesion in the terminal stage; the blue box indicates the representative tissue, where the enlarged image in B and C can be found. A and B. The white asterisks (*) indicate cells in spreading chlorotic lesion presumably undergoing programmed cell death. B. Merge of bright field image and EGFP. B and C. The pattern of fluorescence shows partially a reticular pattern typical for the endoplasmic reticulum (arrows) and partially a punctate pattern suggesting endoplasmatic reticulum disintegration in cells that likely underwent PCD (arrow heads). A, B and C. EGFP indicates the expression of the non-functional reporter construct PCEP1::pre-pro-3xHA-EGFP-KDEL.
