Cytogenetic mapping of H1 histone and ribosomal RNA genes in hybrids between catfish species Pseudoplatystoma corruscans and Pseudoplatystoma reticulatum.

abstract：:It is widely accepted that the H2AX histone in its phosphorylated form (gamma-H2AX) is related to the repair of DNA double-strand breaks (DSBs). In several organisms, gamma-H2AX presence has been demonstrated in meiotic processes such as recombination and sex chromosome inactivation during prophase I (from leptotene t...
