Characterization of the genome of bald cypress.

ABSTRACT:

Background

Bald cypress (Taxodium distichum var. distichum) is a coniferous tree of tremendous ecological and economic importance. It is a member of the family Cupressaceae which also includes cypresses, redwoods, sequoias, thujas, and junipers. While the bald cypress genome is more than three times the size of the human genome, its 1C DNA content is amongst the smallest of any conifer. To learn more about the genome of bald cypress and gain insight into the evolution of Cupressaceae genomes, we performed a Cot analysis and used Cot filtration to study Taxodium DNA. Additionally, we constructed a 6.7 genome-equivalent BAC library that we screened with known Taxodium genes and select repeats.

Results

The bald cypress genome is composed of 90% repetitive DNA with most sequence
