Navinaxonopsis Cook 1967
No full textSubgenus Navinaxonopsis Cook, 1967 Axonopsis (Navinaxonopsis): Cook, 1974 a, p. 334, figs. 1393, 1397, 1398, 1400, 1406. Diagnosis of adults. Character states of genus Brachypodopsis. Fourth leg of males with tibia slender proximally but greatly expanded distally, and with tarsus curved. Type species. Axonopsis (Navinaxonopsis) abnormipes Cook. Species included. Brachypodopsis (N.) abnormipes (Cook) (India), B. (N.) persica (Pešić) (Iran, Turkey). Distribution. India and western Asia. Discussion. Cook (1974 a) considered Navinaxonopsis to be a subgenus of Axonopsis and Pešić (2004) followed that treatment. Here we propose to transfer the taxon as a subgenus to the genus Brachypodopsis. As in the case of Kalobrachypoda, the species of Navinaxonopsis appear to represent a divergent offshoot of the species complex typified by Brachypodopsis baumi Halik and the status of this taxon will also need to be reevaluated when the phylogeny of the genus Brachypodopsis is more completely known.Published as part of Smith, Ian M., Cook, David R. & Gerecke, Reinhard, 2015, Revision of the status of some genus-level water mite taxa in the families Pionidae Thor, 1900, Aturidae Thor, 1900, and Nudomideopsidae Smith, 1990 (Acari: Hydrachnidiae), pp. 111-156 in Zootaxa 3919 (1) on page 140, DOI: 10.11646/zootaxa.3919.1.6, http://zenodo.org/record/24458
Entropy-driven genome organization
No full textDNA and RNA polymerases active on bacterial and human genomes in the crowded environment of a cell are modeled as beads spaced along a string. Aggregation of the large polymerizing complexes increases the entropy of the system through an increase in entropy of the many small crowding molecules; this occurs despite the entropic costs of looping the intervening DNA. Results of a quantitative cost/benefit analysis are consistent with observations that active polymerases cluster into replication and transcription “factories” in both pro- and eukaryotes. We conclude that the second law of thermodynamics acts through nonspecific entropic forces between engaged polymerases to drive the self-organization of genomes into loops containing several thousands (and sometimes millions) of basepairs
