The highly dynamic satellitomes of cultivated wheat species.

ABSTRACT:

Background and aims

Durum wheat, Triticum turgidum, and bread wheat, Triticum aestivum, are two allopolyploid species of very recent origin that have been subjected to intense selection programmes during the thousands of years they have been cultivated. In this paper, we study the durum wheat satellitome and establish a comparative analysis with the previously published bread wheat satellitome.

Methods

We revealed the durum wheat satellitome using the satMiner protocol, which is based on consecutive rounds of clustering of Illumina reads by RepeatExplorer2, and we estimated abundance and variation for each identified satellite DNA (satDNA) with RepeatMasker v4.0.5. We also performed a deep satDNA family characterization including chromosomal location by fluorescence in situ
