Description | OsNAS1 is expressed in cells involved in long-distance transport of Fe. Transcript of OsNAS1 was detected in Fe-sufficient roots but not in leaves, and levels increased markedly in both root and leaves in response to Fe deficiency. Promoter-GUS analysis showed that OsNAS1 was expressed in Fe-sufficient roots in companion cells and pericycle cells adjacent to the proxylem. With Fe deficiency, OsNAS1 and OsNAS2 expression extended to all root cells along with an increase in phytosiderophore secretion, and vascular bundles of green leaves and in call cells of leaves showing severe chlorosis. |
