Dynamics of nuclear matrix attachment regions during 5th instar posterior silk gland development in Bombyx mori

Table 2 TEs associated with posterior silk gland NuMat: Repeat Masker was used with rmblast by masking interspersed and simple repeats against Drosophila TE database. L1Bm and R1Bmks were identified in the three datasets using BLAST2 (hits with > = 90% percent identity and > =100 bp were considered)
