Abstract

Arabidopsis trichome is specialized structure that develops from epidermal cells, and is an excellent model system for studying various aspects of plant cell development and cell differentiation. Our previous studies have shown that C2H2 zinc finger protein family genes, including GIS , GIS2 , GIS3 , ZFP5 , ZFP6 and ZFP8 , play an important role in controlling trichome initiation in Arabidopsis . Here, our novel results showed a C2H2 zinc finger protein, ZFP1 , which also plays an important role in trichome initiation in Arabidopsis . ZFP1 over-expression lines display significantly increased trichome number on cauline leaves, lateral branches and main stems in comparison with wild type plants. ZFP1 RNAi lines and loss-of-function mutants showed the opposite phenotype. Furthermore, our study also found that ZFP1 mediates the regulation of trichome initiation by cytokinin signaling. The molecular and genetic analyses reveal that ZFP1 acts upstream of key trichome initiation factors, GL3 and TRY .
