Variations in ribosomal DNA and mitochondrial DNA among chromosomal species of subterranean mole rats.
Restriction site variations in nuclear ribosomal DNA (rDNA) spacers and mitochondrial DNA (mtDNA) were examined in several populations of mole rats with variable numbers of chromosomes, which represented the two superspecies Spalax leucodon (2n = 38, 54, or 62) and Spalax ehrenbergi (2n = 52, 54, 58, or 60). Sequence divergence of rDNA spacers between the members of the superspecies was approxi...
متن کاملRibosomal DNA (rDNA) spacer polymorphism in mole rats.
Genetic differentiation of ribosomal DNA (rDNA) nontranscribed-spacer (NTS) polymorphism was analyzed in 50 individuals from 13 populations among the four chromosomal species (2n = 52, 2n = 54, 2n = 58, and 2n = 60) of subterranean mole rats of the Spalax ehrenbergi complex in Israel. Southern blot analysis with a mouse rDNA probe and two restriction enzymes, EcoRI and BamHI, revealed various s...
متن کاملMitochondrial DNA polymorphisms in subterranean mole-rats of the Spalax ehrenbergi superspecies in Israel, and its peripheral isolates.
Patterns of mitochondrial DNA (mtDNA) variation were examined in 133 mole-rats constituting all four chromosomal species (2n = 52, 2n = 54, 2n = 58, and 2n = 60) of the Spalax ehrenbergi superspecies in Israel, as well as the peripheral isolates of 2n = 60. In the main range of the complex, a total of 28 mtDNA haplotypes were found in 64 mole-rats, with most haplotypes being unique to either a ...
متن کاملDNA sequence variation in the mitochondrial control region of subterranean mole rats, Spalax ehrenbergi superspecies, in Israel.
The complete mitochondrial control region was sequenced for 60 individuals representing different populations for each of the four species of the subterranean mole rat Spalax ehrenbergi superspecies in Israel: Spalax galili (2n = 52), S. golani (2n = 54), S. carmeli (2n = 58), and S. judaei (2n = 60). The control region of all species and populations is very similar both in length (979 to 983 b...
متن کاملAdaptation of Pelage Color and Pigment Variations in Israeli Subterranean Blind Mole Rats, Spalax Ehrenbergi
BACKGROUND Concealing coloration in rodents is well established. However, only a few studies examined how soil color, pelage color, hair-melanin content, and genetics (i.e., the causal chain) synergize to configure it. This study investigates the causal chain of dorsal coloration in Israeli subterranean blind mole rats, Spalax ehrenbergi. METHODS We examined pelage coloration of 128 adult ani...
