Mitochondrial DNA Sequence Divergence among Lycopersicon and Related Solanum Species.

abstract：:The Mus101 family of chromosomal proteins, identified initially in Drosophila, is widely conserved and has been shown to function in a variety of DNA metabolic processes. Such functions include DNA replication, DNA damage repair, postreplication repair, damage checkpoint activation, chromosome stability, and chromosom...
