“…This result is congruent with DNNDNA hybridization studies (Brownell, 1983;Chevret et al, 1993a, unpublished;Catzeflis et al, 1992Catzeflis et al, , 1993. From a paleontological point ofview, recent studies (Jaeger et al, 1985;De Bruyn and Hussain, 1985;Tong, 1989;Tong and Jaeger, 1993) proposed the separation of Gerbillinae and Murinae from a common ancestor at =16-18 Mybp.…”

Phylogenetic relationships among 40 extant species of rodents, with an emphasis on the taxonomic sampling of Muridae and Dipodidae, were studied using sequences of the nuclear protein-coding gene LCAT (lecithin cholesterol acyl transferase). Analysis of 804 bp from the exonic regions of LCAT confirmed many traditional groupings in and around Muridae. A strong support was found for the families Muridae (represented by 29 species) and Dipodidae (5 species). Compared with Sciuridae, Gliridae, and Caviomorpha, the Dipodidae family appeared the closest relative of Muridae, confirming the suprafamilial Myodonta concept. Within the speciose family Muridae, the first branching leads to the fossorial Spalacinae and semifossorial Rhyzomyinae. The remaining components of Muridae appear as a polytomy from which are issued Sigmodontinae, Calomyscinae, Arvicolinae, Cricetinae, Mystromyinae, Nesomyinae, and some Dendromurinae (Steatomys and Dendromus). This phylogeny is interpreted as the result of a bushlike radiation at the end of the early Miocene, leading to emergence of most living subfamilies. The separation between three additional taxa, Murinae, Gerbillinae, and "Acomyinae" (which comprises the genera Acomys, Deomys, Uranomys, and Lophuromys), has occurred more recently from a common ancestor issued from the main basal radiation. As previously shown by other molecular studies, the vlei rats, Otomyinae, are nested within Old World Murinae. ln the same way, the zokors, Myospalacinae, appear strongly nested within the hamsters, Cricetinae. Finally, we propose a sister group relationship between Malagasy Nesomyinae and south African Mystromyinae. @2000Academic Press

“…Of the 294 nucleotide substitutions, 101 could be specifically localized to the rodential branch. This is consistent with the reportedly higher rate of mutations that has been observed in the evolution of rodentia (Brownell 1983;Wu and Li 1985). The distribution of this selected group of nucleotide substitutions is not shown, but it is virtually identical to the distribution of all of the nucleotide substitutions.…”

“…The NPH values reported for the C. dryophila group ranged down to 37%. Similar NPH values in other eukaryotes correspond to different subfamilies of rodents (14), orders of birds (17), superfamilies of primates (20), species of insects (13), and different sections of a single genus in higher plants (15). This level of divergence is startling for a group conventionally viewed as a single species.…”

Extensive genetic divergence associated with speciation in filamentous fungi

Little is known about genetic differentiation during speciation in fungi. (5), as well as four in Europe (6).In this paper, we report on mating relationships between allopatric intersterility groups from Europe, North America, and Asia. To assess the level ofgenetic divergence associated with intersterility and with allopatry, we compared different strains of these fungi by the technique of DNADNA hybridization. Our results show that speciation in filamentous fungi is accompanied by a high degree of genetic divergence, reflected in greatly reduced base sequence complementarity. The reduction in DNA sequence homology also appears to be associated with geographic isolation and suggests that speciation in these fungi is primarily allopatric in mode.
