Three different complete mariner elements were found in the genome of the ant Tapinoma nigerrimum. One (Tnigmar-Mr) was interrupted by a 900-bp insertion that corresponded to an incomplete member of a fourth mariner element, called Azteca. In this work, we isolate and characterize full-length Tnigmar-Az elements in T. nigerrimum. The purpose of this study is to clarify the evolutionary history of...
To date, only three types of full-length mariner elements have been described in ants, each one in a different genus of the Myrmicinae subfamily: Sinvmar was isolated from various Solenopsis species, Myrmar from Myrmica ruginodis, and Mboumar from Messor bouvieri. In this study, we report the coexistence of three mariner elements (Tnigmar-Si, Tnigmar-Mr, and Tnigmar-Mb) in the genome of a single species,...
The satellite DNA of ants Messor barbarus and Messor bouvieri is analysed. The results are compared with the satellite DNA data from Messor structor previously reported and with new data obtained from the genome of geographically distinct M. structor population, which have shown that this satellite DNA is highly conserved within the species. The satellite DNA is organized as tandemly repeated 79 bp...
