To determine whether mutation of viral 3' processing signals was responsible for continued hnRNP A2/B1 expression, a 500 base pair region spanning the polyadenylation signal in the 5' LTR was amplified from integrated provirus DNA and sequenced.
As a consequence, we identified several previously unreported families of rice LTR retrotransposons consisting of non-coding and, in some cases, repeating, sequence motifs.
RTs of families in this clade show high sequence similarity to an LTR retrotransposon in pineapple (~70% to Acr-1; CAA73042) and to one in Sorghum bicolor (~77% to Retrosor3 , AAD221153) (Figure 2).
IGFR, [ 29 ] ], and one study used several cell lines and demonstrated distinct effects of the cell genetic background [ 25 ] . Down-regulated genes include bFGF, FGF-2, Topoisomerase II-α, EGFR,, human HDAC1, as well as cell cycle regulatory genes among others [ 30 31 32 33 34 35 36 37 ] . Regions in the bFGF promoter have been identified as associated with density-dependent down-regulation of bFGF [ 31 ] . The IGF-II P3 promoter is down-regulated as a function of cell density, and a 7-base pair sequence has been identified that plays a critical role in this down-regulation [ 32 ] . Neither the MoMuLV LTR or the htk promoters encode this sequence, although both encode a 10-base pair sequence that is identical to the P3 sequence with an insertion of 3 base pairs at position -1081.
Our laboratory is in the process of screening the GenBank rice ( Oryza sativa ) database (GBRD) and the Monsanto rice dataset (MRD) for the presence of LTR retrotransposons.
