Comprehensive analysis of CCCH zinc finger family in poplar (Populus trichocarpa).

ABSTRACT:

Background

CCCH zinc finger proteins contain a typical motif of three cysteines and one histidine residues and serve regulatory functions at all stages of mRNA metabolism. In plants, CCCH type zinc finger proteins comprise a large gene family represented by 68 members in Arabidopsis and 67 in rice. These CCCH proteins have been shown to play diverse roles in plant developmental processes and environmental responses. However, this family has not been studied in the model tree species Populus to date.

Results

In the present study, a comprehensive analysis of the genes encoding CCCH zinc finger family in Populus was performed. Using a thorough annotation approach, a total of 91 full-length CCCH genes were identified in Populus, of which most contained more than one CCCH motif a
