Differential expression of miRNAs in the presence of B chromosome in the cichlid fish Astatotilapia latifasciata.

ABSTRACT:

Background

B chromosomes (Bs) are extra elements observed in diverse eukaryotes, including animals, plants and fungi. Although Bs were first identified a century ago and have been studied in hundreds of species, their biology is still enigmatic. Recent advances in omics and big data technologies are revolutionizing the B biology field. These advances allow analyses of DNA, RNA, proteins and the construction of interactive networks for understanding the B composition and behavior in the cell. Several genes have been detected on the B chromosomes, although the interaction of B sequences and the normal genome remains poorly understood.

Results

We identified 727 miRNA precursors in the A. latifasciata genome, 66% which were novel predicted sequences that had not been identified
