Comparative analyses of DNA repeats and identification of a novel Fesreba centromeric element in fescues and ryegrasses

Background Cultivated grasses are an important source of food for domestic animals worldwide. Increased knowledge of their genomes can speed up the development of new cultivars with better quality and greater resistance to biotic and abiotic stresses. The most widely grown grasses are tetraploid ryegrass species ( Lolium ) and diploid and hexaploid fescue species ( Festuca ). In this work, we characterized repetitive DNA sequences and their...
