Zinc finger protein (ZFP) in plants-a review

Zinc finger protein (ZFP) possesses one or more 'zinc finger' that bond one or more zinc ions by its residues Histidine (His) and Cysteine (Cys). ZFP also belongs to a large family of transcription factor. It plays many important regulatory roles in plants. Here, we explained that the percentage of ZFP transcription factor in total transcription factors is similar among plant species. The ZFP functions were implicated in development, growth, stress response and phytohormone responses based on the conclusion of four ZFP families, C2H2, CCCH, C3HC4 and C4. Meanwhile, there was one main function in each ZFP family. On the basis of analyses of the ZFP gene expression in the CCCH family of rice, the regulation controlled by rice ZFP in various tissues was significantly related with each other, as well as in responses to different abiotic stresses. Expression of some rice tissues-specific ZFP genes was significantly related to abiotic or biotic stresses.
