Cloning of stress-related transcription factor genes from cotton by optimized TAIL-PCR.
2010
ABF/AREB/ABI5/DPBF transcription factors belong to basic leucine zipper protein,this kind of transcription factors plays an important role in the signal transduction pathways of ABA-dependent abiotic stress.In this study,taking structure char-acteristics of ABF/AREB/ABI5/DPBF as the research object,we cloned three bZIP encoding genes by 3′ RACE successfully from cotton and also optimized the TAIL-PCR conditions.The further experiment results showed that we had got the integrated sequences of the ORF,3′ UTR,as well as part of 5′ UTR sequence.The genes we cloned will provide candidate genes for resis-tance genetic engineering of cotton.Furthermore,the optimized methodology of TAIL-PCR will provide an easy and efficient technology for cloning of target genes.
