Abstract
We have constructed a full BAC library for the superior early indica variety of Oryza sativa, Guang Lu Ai 4. The MAX Efficiency DH10B with increased stability of inserts was used as BAC host cells. The potent pBelo BACII with double selection markers was used as cloning vector. The cloning efficiency we have reached was as high as 98%, and the transformation efficiency was raised up to 106 transformants / μg of large fragment DNA. The BAC recombinant transformants were picked at random and analyzed for the size of inserts, which turned out to be of 120 kb in length on average. We have obtained more than 20,000 such BAC clones. According to conventional probability equation, they covered the entire rice genome of 420,000 kb in length. The entire length of inserts of the library obtained has the 5- to 6- fold coverage of the genome. To our knowledge, this is the first reported full BAC library for a complex genome.
