An analysis of segmentation dynamics throughout embryogenesis in the centipede Strigamia maritima
TLDR
The data suggest that dynamic patterning of gene expression may be widespread among the arthropods, but that a single network of segmentation genes can generate either oscillatory behavior at pair-rule periodicity or direct single segment patterning, at different stages of embryogenesis.
Segmentation of the millipede trunk as suggested by a homeotic mutant with six extra pairs of gonopods
TLDR
A very likely early determination of the sites of the future metamorphosis of walking legs into gonopod and a segmentation process according to the multiplicative model may provide a detailed explanation for the distribution of the extra gonopods in the homeotic specimen.
The centipede Strigamia maritima: what it can tell us about the development and evolution of segmentation.

TLDR
Strigamia maritima turns out to be a tractable system both at the ecological level of investigating differences in mean segment number between populations and at the molecular level of studying the expression patterns of developmental genes, including the recent finding of a double-segment periodicity in the expression of two Strigamia segmentation genes.
Gene expression suggests double-segmental and single-segmental patterning mechanisms during posterior segment addition in the beetle Tribolium castaneum.

TLDR
The data suggest the presence of another (or modified), yet undiscovered, mechanism of posterior segment addition in one of the best-understood arthropod models, and the finding of a hitherto unrecognized segmentation mechanism in Tribolium may have major implications for the understanding of the origin of segmentation mechanisms.
Trunk segment numbers and sequential segmentation in myriapods

    Evolution & development
  • 2005
TLDR
This work can at least outline the distinctive role in segmentation of a proliferative zone in the embryo, and suggests that these patterns result from multi‐layered developmental processes, where gene expression and epigenetic mechanisms interact in a nonstrictly hierarchical way.
Regulation and function of odd-paired in Tribolium segmentation
TLDR
The findings suggest that Tc-opa expression is regulated by the pair-rule gene network even though its requirement for segmentation is uncertain in Tribolium.
Segment polarity gene expression in a myriapod reveals conserved and diverged aspects of early head patterning in arthropods

  • 2012
TLDR
The present study shows that in the myriapod Glomeris marginata the early expression of hh is also in a broad anterior domain, but this domain corresponds only to the ocular and antennal segment, suggesting that the mandibular segment may have a special function in anterior patterning.
Arthropod segmentation
TLDR
It is argued that the gene regulatory network that patterns segments may be relatively conserved, although the timing of segmentation varies widely, and double-segment periodicity appears to have evolved at least twice.
A segmentation clock operating in blastoderm and germband stages of Tribolium development
TLDR
It is shown that segmentation at both blastoderm and germband stages of Tribolium is based on a segmentation clock, and it is found that neither cell movement nor oriented cell division could explain the observed wave dynamics of Tc-eve.

The pattern of segment formation, as revealed by engrailed expression, in a centipede with a variable number of segments
TLDR
The way in which segments are formed using in situ hybridization to demonstrate the expression pattern of the engrailed gene during embryogenesis is investigated, and how natural selection might act on this intraspecific developmental variation is considered.
Early development and segment formation in the centipede, Strigamia maritima (Geophilomorpha)
TLDR
The classic description of centipede development contains a fundamental error in the identification of the axes and hence in the interpretation of early segmentation, which provides a foundation for further developmental studies of the Geophilomorpha.
Exploring myriapod segmentation: the expression patterns of even-skipped, engrailed, and wingless in a centipede.
TLDR
The adjacent expression of the engrailed and wingless stripes suggests that the regulatory relationship between the two genes may be conserved in the centipede, and thus this pathway may be a fundamental mechanism of segmental development in most arthropods.
Myriapod metamerism and arthropod segmentation
TLDR
An improved model for arthropod segmentation is sketched, with some doubt about the homology between annelid and arthropody segmentation, and the final repetitive pattern is defined as metasegmental.
Expression of pair-rule gene homologues in a chelicerate: early patterning of the two-spotted spider mite Tetranychus urticae
TLDR
The expression pattern of Tu-pax3/7 lends support to the possibility that a pair-rule patterning mechanism is active in the segmentation pathways of chelicerates.
Expression patterns of hairy, even-skipped, and runt in the spider Cupiennius salei imply that these genes were segmentation genes in a basal arthropod.
TLDR
Analysis of the expression of three segmentation genes of the pair-rule class in the spider Cupiennius salei implies that the involvement of hairy, even-skipped, and runt in arthropod segmentation is an ancestral character for arthropods and is not restricted to a particular group of insects.
Bowl is required downstream of Notch for elaboration of distal limb patterning
TLDR
The bowl gene is required for the elaboration of pattern in the tarsus and its effects suggest a progressive model for the determination of P/D identities.
The pattern of variation in centipede segment number as an example of developmental constraint in evolution
TLDR
An approach based on Bayesian inference is used to quantify the probability of obtaining the observed distribution of values given a null model in which developmental constraint is absent, and concludes that constraint must be involved in centipede evolution.
Latitudinal cline in segment number in an arthropod species, Strigamia maritima

TLDR
A latitudinal cline in segment number is revealed in the geophilomorph species Strigamia maritima: segment number in British populations decreases with distance north, the first such cline to be reported for any centipede species.
Posterior patterning genes and the identification of a unique body region in the brine shrimp Artemia franciscana
TLDR
It is argued that the post-genital segments of Artemia constitute a unique body region that bears no obvious homology to previously characterised domains of Hox gene activity, and may play a role in the generation of body segments in insects.
