Abstract: Loblolly pine (LP; Pinus taeda L.) is the most economically important tree in the U.S. and a cornerstone species in southeastern forests. However, genomics research on LP and other conifers has lagged behind studies on flowering plants due, in part, to the large size of conifer genomes. As a means to accelerate conifer genome research, we constructed a BAC library for the LP genotype 7-56. The LP BAC library consists of 1,824,768 individually-archived clones making it the largest single BAC library constructed to date, has a mean insert size of 96 kb, and affords 7.6X coverage of the 21.7 Gb LP genome. To demonstrate the efficacy of the library in gene isolation, we screened macroarrays with overgos designed from a pine EST anchored on LP chromosome 10. A positive BAC was sequenced and found to contain the expected full-length target gene, several gene-like regions, and both known and novel repeats. Macroarray analysis using the retrotransposon IFG-7 (the most abundant repeat in the sequenced BAC) as a probe indicates that IFG-7 is found in roughly 210,557 copies and constitutes about 5.8% or 1.26 Gb of LP nuclear DNA; this DNA quantity is eight times the Arabidopsis genome. In addition to its use in genome characterization and gene isolation as demonstrated herein, the BAC library should hasten whole genome sequencing of LP via next-generation sequencing strategies/technologies and facilitate improvement of trees through molecular breeding and genetic engineering. The library and associated products are distributed by the Clemson University Genomics Institute (www.genome.clemson.edu).

- kastevens@ucdavis.edu:
- The files labeled TIL_XXX_FC70M6V_Y_00Z, are Drosophila libraries with a median target insert size of XXX. They come in pairs and can be merged.
- Regarding pairing, each insert size was run in two lanes Y at two different concentrations.
- Lane 3, with the lower concentration, should have higher quality data than lane 2 but with a higher cost per bp.
- The loss in quality was quantitativly small, so we don't expect the extra expense of lowering the concentration will be justified empirically.
- The first library, FC70M6V_6_001, is a ~40x library created from a pool of ~1000 fosmids. In general, we do not put the insert size in the filename.
- However, we did estimate the insert size to be 343bp with a below median standard deviation of 30. So roughly 15% of the inserts are < 313bp and have > 3bp overlap. This seems to fit well with your result.
- Each lane is multiplexed into sub-lanes indicated by 00Z. So the amount of reads in the file is variable and not nessesarily reflective of the cluster density.
- The Drosophila libraries were each run in 1/4 lane and the fosmid pool was run in 1/2 lane. The pool has roughy double the sequence content of the
- Drosophila libraries run in lane 2 at nominal density.
