Abstract: A yeast two-hybrid cDNA library derived from roots of Gossypium barbadense cv. Pima90-53 inoculated with severe virulence Verticillium dahliae was constructed based on SMARTIM technique and homologous recombination reaction. Detection of the library indicated that its capacity and titer were 2.82×106 and 5.02×108 cfu/mL, respectively. The result from colony PCR showed that the length of insert cDNA fragments ranged from 500 to 1 500 bp on average and the recombination rate was 93.33%. These results demonstrate that the library meets the demands of the standard cDNA library, which will be useful for screening interaction proteins, determining signal transduction components and analyzing the structure and function of disease-resistant proteins in the future.
