Leaf cells are different between adaxial and abaxial domains of the same leaf.
Such cell differentiations are known to be regulated by several genes expressing specifically in the adaxial or abaxial domains. However, the molecular mechanisms determining these gene expression domains remain to be elucidated. We have analyzed the mechanism regulating FILAMENTOUS FLOWER (FIL), one of abaxial genes, by molecular genetic approach.
We isolated a novel Arabidopsis mutant enlarged fil expression domain2 (enf2) which showed broader FIL expression domain. Recently, we found that in very early stages, FIL expression domain in wild type plant was as broad as in enf2 plant. Thus ENF2 gene may act as regulator to gradually reduce the size of FIL expression domain during leaf development.
Now we are analyzing the transition of FIL expression pattern during leaf development in wild type and enf2 and attempting to reveal the ENF2 function associating with this transition.
