MYB transcription factor PtrMYB01 in Populus tomentosa Carr and cloning method of cDNA of PtrMYB01and application thereof

The invention provides a novel MYB transcription factor PtrMYB01 in Populus tomentosa Carr, a gene coding the transcription factor, and a cloning method of cDNA, wherein, the transcription factor is polypeptide which is obtained by the separation of Populus tomentosa Carr. By analyzing a highly homologous transcription factor ATMYB60 which belongs the same family with the transcription factor PtrMYB01, the transcription factor PtrMYB01 has possible functions of regulating and controlling plant stress resistance (drought resistance) and regulating anabolism of plant flavonoids. Accordingly, if the recombinant plasmid of the PtrMYB01 gene is transferred into the plant, because the gene is overexpressed in the plant, a drought-resistant cold-resistance plant can be produced, so that the plant yield is increased. The cloning method comprises the following steps: extracting total RNA from Populus tomentosa Carr, and carrying out inverse transcription on the total RNA to synthesize cDNA; designing primers according to the conserved sequence of the transcription factor, and amplifying into a DNA fragment through chain polymerization enzyme reaction; purifying the amplified products, cloning the purified products to a pCXSN vector, transferring a DH5 alfa cell, and culturing overnight in plate. The transferred escherichia coli plasmid is extracted and transferred into Agrobacterium EHA105 for subsequent research.
