Construction of BAC libraries derived from the ascidian Ciona intestinalis

抄録

Large insert genomic bacterial artificial chromosome (BAC) libraries were constructed from a basal chordate, the ascidian Ciona intestinalis. Insert analyses of randomly selected clones indicated that in the first library the mean insert size was 135 kb and predicted a 15-fold coverage of the Ciona genome, and in the second library the mean insert size was 165 kb and predicted a 5-fold coverage of the genome. These first large insert genomic libraries of the ascidian should increase the speed of genomic analyses of basal chordates.
