Spatial and Temporal Distribution of Sucrose Synthase in the Radish Hypocotyl in Relation to Thickening Growth
(2001) In Plant and Cell Physiology 42(6). p.583-593- Abstract
- Sucrose synthase (SuSy) is a key enzyme in the development of storage root of radish. Clarification of its spatial and temporal expression during the thickening growth of radish hypocotyl, which later develops into storage root, was carried out immunologically using light microscopy. Sequential harvests at 3, 7, 11 and 13 d after sowing (DAS) were performed on two radish cultivars having different sink capacity. A very low level of SuSy was observed 3 DAS for both cultivars. White Cherrish (WC; strong storage root) showed the maximum level of SuSy between 7 and 11 DAS with increased cell development (thickening), while in Kosena (K; low storage root) the level remained high after 13 d of growth. A high level of SuSy was found in companion... (More)

A high level of SuSy was found in companion cells, which was consistent with previous observations, but SuSy was also found in the xylem parenchyma and in some cortical cells. The level of SuSy differed according to the localization and depended highly on cell development. Both cell division and cell enlargement were stimulated in WC compared with K. The role of SuSy during thickening growth of radish hypocotyl is discussed in terms of utilizing photosynthates. (Less)
