| The sugarcane expressed sequence tag (SUCEST) project has produced a large number of cDNA sequences from several plant tissues submitted or not to different conditions of stress. In this paper we report the result of a search for transposable elements (TEs) revealing a surprising amount of expressed TEs homologues. Of the 260,781 sequences grouped in 81,223 fragment assembly program (Phrap) clusters, a total of 276 clones showed homology to previously reported TEs using a stringent cut-off value of e-50 or better. Homologous clones to Copia/Ty1 and Gypsy/Ty3 groups of long terminal repeat (LTR) retrotransposons were found but no non-LTR retroelements were identified. All major transposon families were represented in sugarcane including Activator (Ac),... |

| Transposable elements (TEs) account for a large portion of plant genomes, particularly in grasses, in which they correspond to 50%-80% of the genomic content. TEs have recently been shown to be a source of new genes and new regulatory networks. The most striking contribution of TEs is referred as molecular domestication, by which the element coding sequence loses its movement capacity and acquires cellular function. Recently, domesticated transposases known as mustang and derived from the Mutator element have been described in sugarcane. In order to improve our understanding of the function of these proteins, we identified mustang genes from Sorghum bicolor and Zea mays and performed a phenetic analysis to assess the diversity and evolutionary history of... |
