leaf | OsNAS1 and OsNAS2 transcripts are not detected in Fe-sufficient roots, OsNAS3 transcript is present, expression is suppressed in response to Fe deficiency. In Fe-deficient plants, OsNAS1 and OsNAS2 are expressed in the vascular bundles of green leafes showing severe chlorosis. OsNAS3 expression is restricted to companion cells of leaves irrespective of Fe status | Oryza sativa | - |
root | OsNAS1 and OsNAS2 transcripts are detected in Fe-sufficient roots, very low in roots of Fe-sufficient plants. OsNAS3 transcript is very low in roots of Fe-sufficients plants. OsNAS3 expression is induced in response to Fe deficiency. OsNAS1 and OsNAs2 are expressed in Fe-sufficient roots in companion cells and pericycle cells adjacent to the protoxylem. With Fe deficiency, OsNAS1 and OsNAS2 expression extends to all root cells along with an increase in phytosiderophore secretion. OsNAS3 expression is restricted to the pericycle and companion cells of the roots, irrespective of Fe status | Oryza sativa | - |
