Using the homologybased cloning, we obtained a Fbox/LRR repeat protein 14 gene (TaFBL14) from wheat in the present study. TaFBL14 encoded a 486 aa polypeptide with predicted molecular weight of 53.48 kD and theoretical isoelectric point 5.93. The deduced protein included a Fbox domain in the Nterminal and 7 LRR domains in the Cterminal. No signal peptide and nuclear localization sequence were detected. Subcellular localization showed TaFBL14 mainly expressed in the cytoplasm. αhelix was the most important secondary structure, which made TaFBL14 the globular protein. Neighbourjoining tree showed that the deduced TaFBL14 protein shared high similarity with FBL14 from Aegilops tauschii and Triticum urartu. Quantitative reverse transcription PCR showed that TaFBL14 mainly expressed in wheat young leaves and flag leaves, and were upregulated expression from 6 hpi to 96 hpi. These results implied that TaFBL14 may be involved in wheat resistant to leaf rust pathogen infection.
