- Abstract
- The Arabidopsis genome contains 10 genes
belonging to the HD-Zip II family including ATHB2 and
HAT2. Previous work has shown that ATHB2 is rapidly and
strongly induced by light quality changes that provoke the
shade avoidance response whereas HAT2 expression
responds to auxin. Here, we present a genome-wide analysis
of the HD-Zip II family. Phylogeny reconstruction revealed
that almost all of the HD-Zip II genes can be subdivided into
4 clades (a-d), each clade comprising 2-3 paralogs. Gene
expression studies demonstrated that all the c and d genes
are regulated by light quality changes. Kinetics of induction,
low R/FR/high R/FR reversibility and auxin response
analyses strongly suggested that HAT1, HAT3 and ATHB4,
as ATHB2, are under the control of the phytochrome system
whereas HAT2 is up-regulated by low R/FR as a consequence
of the induction of the auxin signaling pathway
provoked by FR-rich light. Root and shoot digital in situ
revealed that c and d genes are also tightly regulated during
plant development with both distinct and overlapping
patterns. Phenotypes of gain of function and dominant
negative lines demonstrated that one or more of the HD-Zip
II c genes negatively regulate cell proliferation during leaf
development in a high R/FR light environment. Finally,
target gene analysis using a chimeric transcription factor
(HD-Zip2-V-G), known to activate ATHB2 target genes in a
glucocorticoid-dependent manner, revealed that all the 10
HD-Zip II genes can be recognized by the HD-Zip 2 domain
in vivo, implying an intricate negative feedback network. (literal)
