Analysis of Insertional Sites of the SIRE Retroelement Family from Glycine Max Using GenBank BAC-end Sequences

摘要

SIREI is a 2,000-copy member of the Tyl/copia retroelement family found in the soybean genome and is closelyrelated to sireviruses found in the genomes of other legumes. Although these elements closely resemble typical plant membersof the Ty l/copia family, they are unusual in that they possess an envelope-like coding region immediately downstream of thereverse transcriptase gene. Despite its copy number, very few members of the SIRE1 family are currently present in publiclyavailable genomic assemblies or draft contigs. However, fragments of family members are well-represented as BAC-ends in theGenBank Genome Survey Sequence database. This database was queried using the 5 and 3 ends of
