Abstract:

The cDNA library of Yuanjiang Oryza rifupongon leaf was constructed by using SMARTTM technology. The titers of the non-amplified library and the amplified library were 1.1×10⁶ pfu/mL and 3.98×10⁷ pfu/mL, respectively. The recombi-nation rate was more than 91%. The DNA sequence length of the most cDNAs in the library was between 500-2 000 bp. Some cDNAs chosen by random were sequenced. After BLAST analysis of some cDNAs, their possible function were pre-dicted. It is found that these cDNAs show 98% similarity to Oryza sativa japonica in the NCBI database. These provided a base for further study on the structure and function of these cDNAs and evolutionary process of Yuanjiang Oryza rifupongon .
