In situ localization of CSVd in SAM of the CSVd infected Argyranthemum plants. (A) Longitudinal sections of healthy shoot tips of ‘Border Dark Red’. (B) Longitudinal section of CSVd-infected shoot tip of ‘Yellow Empire’. (C) Longitudinal section of CSVd-infected shoot tip of ‘Border Dark Red’. (D) Longitudinal section of CSVd-infected SAM of ‘Yellow Empire’ [higher magnification of the SAM in (B)]. (E) Longitudinal section of CSVd-infected shoot apical meristem (SAM) of ‘Border Dark Red’ [higher magnification of the SAM in (C)]. (F) Cross section of CSVd-infected shoot tip of ‘Yellow Empire’. (G) Cross section of CSVd-infected shoot tip of ‘Border Dark Red’. (H) Longitudinal section of CSVd-infected shoot tip of ‘Butterfly’. (I) Longitudinal section of CSVd-infected shoot tip of ‘Border Pink’. AD indicates apical dome (AD), and 1, 2, 3 indicates first, second, and the third leaf primordia, respectively. Scale bars in (A, B, C, H, I) are 310 μm; scale bars in (D–G) are 100 μm.
