Cloning and expression pattern of bZIP25 transcription factor from Lonicera macranthoides
Objective To clone the cDNA sequences of bZIP25 gene from Lonicera macranthoides,and conduct bioinformatics analysis and expression pattern analysis,to determine the biological function of bZIP25 in Lonicera macranthoides.Methods The full length of bZIP25 sequence was cloned with reverse transcription PCR technology.bZIP25 and its encoded proteins were analyzed with bioinformatics analysis methods.Its expression level in the stems,leaves and seven flowering stages were determined by real-time fluorescence quantitative PCR technology.Results The LmbZIP25(OR551766)gene was cloned,and 191 amino acids encoded.It contained a typical bZIP family structure and high homology with other plants in the bZIP domain.The LmbZIP25 gene had tissue specificity and its expression level in the stem was much higher than that in the flowers and leaves.The highest expression occurred level in the yellow bud stage among the seven flowering stages.Conclusion The full length of LmbZIP25 gene is cloned and its expression differences in organs and flowering stages are analyzed,laying a foundation for further exploring its biological functions in the floral development of Lonicera macranthoides.
