Survey of transposable elements from rice genomic sequences.
Oryza sativa L. (domesticated rice) is a monocotyledonous plant, and its 430 Mb genome has been targeted for complete sequencing. We performed a high-resolution computer-based survey for transposable elements on 910 Kb of rice genomic DNA sequences. Both class I and II transposable elements were present, contributing 19.9% of the sequences surveyed. Class II elements greatly outnumbered class I...
متن کاملRice transposable elements: a survey of 73,000 sequence-tagged-connectors.
As part of an international effort to sequence the rice genome, the Clemson University Genomics Institute is developing a sequence-tagged-connector (STC) framework. This framework includes the generation of deep-coverage BAC libraries from O. sativa ssp. japonica c.v. Nipponbare and the sequencing of both ends of the genomic DNA insert of the BAC clones. Here, we report a survey of the transpos...
متن کاملMITE-Hunter: a program for discovering miniature inverted-repeat transposable elements from genomic sequences
Miniature inverted-repeat transposable elements (MITEs) are a special type of Class 2 non-autonomous transposable element (TE) that are abundant in the non-coding regions of the genes of many plant and animal species. The accurate identification of MITEs has been a challenge for existing programs because they lack coding sequences and, as such, evolve very rapidly. Because of their importance t...
متن کاملExaptation of protein coding sequences from transposable elements.
The activity of transposable elements (TEs) has had a profound impact on the evolution of eukaryotic genomes. Once thought to be purely selfish genomic entities, TEs are now recognized to occupy a continuum of relationships, ranging from parasitic to mutualistic, with their host genomes. One of the many ways that TEs contribute to the function and evolution of the genomes in which they reside i...
متن کاملNew transposable elements identified as insertions in rice transposon Tnr1.
Tnr1 (235 bp long) is a transposable element in rice. Polymerase chain reactions (PCRs) done with a primer(s) that hybridizes to terminal inverted repeat sequences (TIRs) of Tnr1 detected new Tnr1 members with one or two insertions in rice genomes. Six identified insertion sequences (Tnr4, Tnr5, Tnr11, Tnr12, Tnr13 and RIRE9) did not have extensive homology to known transposable elements, rathe...
