The Caenorhabditis globin gene family reveals extensive nematode-specific radiation and diversification. November 2008; of Figure 2, phylogenetic relationship CeNDR, the Caenorhabditis elegans natural diversity CeNDR offers reduced redundancy of data collection (e.g. whole-genome sequencing) along with consistent data collection and organization as a centralized resource. Additionally, the unification of strain management facilitates studies of natural variation across the wide Caenorhabditis community and beyond. Because CeNDR is built as open-source
Apr 26, 2016 · anisogamy among species (Figure 2C), ranging from an egg:sperm volumetric ratio of 453:1 in C. elegans to 20:1 in C. plicata (Figures 2C to 2E). These findings are consistent with previous conclusions for Caenorhabditis that sexual selection by sperm competition is the key driver in the evolution of male sperm size. Deep sampling of Hawaiian Caenorhabditis elegans Caenorhabditis elegans reveals high genetic diversity and admixture with global populations Tim A Crombie1, Stefan Zdraljevic1,2, Daniel E Cook1,2, Robyn E Tanny1, Shannon C Brady1,2, Ye Wang1, Kathryn S Evans1,2, Steffen Hahnel1, Daehan Lee1, Briana C Rodriguez1, Gaotian Zhang1, Joost van der Zwagg1, Karin Kiontke3, Erik C Andersen1* Developmental Defects in a Caenorhabditis elegans Model The reduction of XBP-1 or IRE-1 activity by RNAi completely suppresses hsp-4 eion in both mutants (Figure 8, C and D, Figure S5, and data not shown). These results suggest that the eion of hsp-4 in atf-6 ( ok551 ) and in gale-1 ( pv18 ) is caused by the activation of xbp-1 .

Author information:(1)Department of Animal Evolutionary Ecology, Zoological Institute, University of Tuebingen, Auf der Morgenstelle 28, 72076 Tuebingen, Germany. [email protected]ingen.de Functional diversification of the nematode mbd2/3 gene Aug 28, 2007 · Several members of the Methyl-Binding Domain protein family link DNA methylation with chromatin remodeling complexes in vertebrates. Amongst the four classes of MBD proteins, MBD2/3 is the most highly conserved and widespread in metazoans. We have previously reported that an mbd2/3 like gene (mbd-2) is encoded in the genomes of the nematodes Pristionchus pacificus, Caenorhabditis Genomic basis of recombination suppression in the hybrid Starting from the SLR derived contigs we produced earlier , we first performed scaffolding using the 100× Hi-C data, resulting in a sharp increase in the scaffold N50 size from 57 kb to 7 Mb, which is approaching a chromosome-level of contiguity (Figure 3B). As a result, we were able to obtain six large contigs, each representing an
Glia are abundant components of animal nervous systems. Recognized 170 years ago, concerted attempts to understand these cells began only recently. From these investigations glia, once considered passive filler material in the brain, have emerged as active players in neuron development and activity. Glia are essential for nervous system function, and their disruption leads to disease. The Glia-Neuron Interactions in Caenorhabditis elegans Glia are abundant components of animal nervous systems.

The High Genetic Diversity in the Chemoreceptor Superfamily of Apr 01, 2005 · CAENORHABDITIS elegans has 1300 predicted genes that encode members of putative chemosensory receptors (T roemel et al. 1995; R obertson 1998, 2000, 2001).Together, these genes define the SR superfamily. On the basis of sequence alignment and phylogenetic trees, SR superfamily members fall into at least a dozen families (H. R obertson, personal communication, and our unpublished data).

RESEARCH ARTICLE Open Access Species richness genus Caenorhabditis from a broad spectrum of substrate types in French Guiana (Figures 1 and 2, Table 1, Additional files 1 and 2). We isolated five different Caenorhabditis species, in addition to a sixth species (C. sp. 12) found in May 2008 that was not found in 2009. Three of these species (C. sp. 12, C.sp.17,andC. sp. 18) The Caenorhabditis globin gene family reveals extensive Globin isoforms with variant properties and functions have been found in the pseudocoel, body wall and cuticle of various nematode species and even in the eyespots of the insect-parasite Mermis nigrescens. In fact, much higher levels of complexity exist, as shown by recent whole genome analysis studies. In silico analysis of the genome of Caenorhabditis elegans revealed an unexpectedly high
Mar 23, 2020 · The free-living nematode Caenorhabditis elegans is a key laboratory model for metazoan biology.C. elegans has also become a model for parasitic nematodes despite being only distantly related to most parasitic species. All of the 65 Caenorhabditis species currently in culture are free-living, with most having been isolated from decaying plant or fungal matter.
