Pattern and process in the evolution of the sole dioecious member of Brassicaceae
EvoDevo - Tập 5 - Trang 1-17 - 2014
Valerie L Soza, Vietnam Le Huynh, Verónica S Di Stilio
Lepidium sisymbrioides, a polyploid New Zealand endemic, is the sole dioecious species in Brassicaceae and therefore the closest dioecious relative of the model plant Arabidopsis thaliana. The attractiveness of developing this system for future studies on the genetics of sex determination prompted us to investigate historical and developmental factors surrounding the evolution of its unisexual flo...... hiện toàn bộ

Breaking evolutionary and pleiotropic constraints in mammals: On sloths, manatees and homeotic mutations
EvoDevo - Tập 2 - Trang 1-27 - 2011
Irma Varela-Lasheras, Alexander J Bakker, Steven D van der Mije, Johan AJ Metz, Joris van Alphen, Frietson Galis
Mammals as a rule have seven cervical vertebrae, except for sloths and manatees. Bateson proposed that the change in the number of cervical vertebrae in sloths is due to homeotic transformations. A recent hypothesis proposes that the number of cervical vertebrae in sloths is unchanged and that instead the derived pattern is due to abnormal primaxial/abaxial patterning. We test the detailed predict...... hiện toàn bộ
Sex-specific and developmental expression of Dmrt genes in the starlet sea anemone, Nematostella vectensis
EvoDevo - Tập 6 - Trang 1-6 - 2015
Nikki G Traylor-Knowles, Eric G Kane, Vanna Sombatsaphay, John R Finnerty, Adam M Reitzel
The molecular mechanisms underlying sex determination and differentiation in animals are incredibly diverse. The Dmrt (doublesex and mab-3 related transcription factor) gene family is an evolutionary ancient group of transcription factors dating to the ancestor of metazoans that are, in part, involved in sex determination and differentiation in numerous bilaterian animals and thus represents a pot...... hiện toàn bộ
Các thành phần của con đường lưng-bụng cũng góp phần vào việc định hình trước-sau trong phôi ong mật (Apis mellifera) Dịch bởi AI
EvoDevo - Tập 5 - Trang 1-11 - 2014
Megan J Wilson, Nathan J Kenny, Peter K Dearden
Một bước quan trọng ban đầu trong quá trình phát triển phôi là thiết lập các trục cơ thể chính; các trục lưng-bụng (DV) và trước-sau (AP). Việc xác định những trục này ở một số loài côn trùng yêu cầu sự hoạt động của các bộ tín hiệu khác nhau cho mỗi trục. Sự hình thành dọc theo trục DV yêu cầu sự tương tác giữa các con đường Toll và Dpp/TGF-β, trong khi sự hình thành dọc theo trục AP yêu cầu các ...... hiện toàn bộ
Ontogenetic differences in localization of glutamine transporter ApGLNT1 in the pea aphid demonstrate that mechanisms of host/symbiont integration are not similar in the maternal versus embryonic bacteriome
EvoDevo - - 2016
Hsiao-ling Lu, Daniel R. G. Price, Athula Wikramanayake, Chun-che Chang, Alex C. C. Wilson
Obligate intracellular symbionts of insects are metabolically and developmentally integrated with their hosts. Typically, reproduction fails in many insect nutritional endosymbioses when host insects are cured of their bacterial symbionts, and yet remarkably little is known about the processes that developmentally integrate host and symbiont. Here in the best studied insect obligate intracellular ...... hiện toàn bộ

Transcriptional dynamics of a conserved gene expression network associated with craniofacial divergence in Arctic charr
EvoDevo - Tập 5 - Trang 1-19 - 2014
Ehsan Pashay Ahi, Kalina Hristova Kapralova, Arnar Pálsson, Valerie Helene Maier, Jóhannes Gudbrandsson, Sigurdur S Snorrason, Zophonías O Jónsson, Sigrídur Rut Franzdóttir
Understanding the molecular basis of craniofacial variation can provide insights into key developmental mechanisms of adaptive changes and their role in trophic divergence and speciation. Arctic charr (Salvelinus alpinus) is a polymorphic fish species, and, in Lake Thingvallavatn in Iceland, four sympatric morphs have evolved distinct craniofacial structures. We conducted a gene expression study o...... hiện toàn bộ
From dinosaurs to birds: a tail of evolution
EvoDevo - Tập 5 - Trang 1-20 - 2014
Dana J Rashid, Susan C Chapman, Hans CE Larsson, Chris L Organ, Anne-Gaelle Bebin, Christa S Merzdorf, Roger Bradley, John R Horner
A particularly critical event in avian evolution was the transition from long- to short-tailed birds. Primitive bird tails underwent significant alteration, most notably reduction of the number of caudal vertebrae and fusion of the distal caudal vertebrae into an ossified pygostyle. These changes, among others, occurred over a very short evolutionary interval, which brings into focus the underlyin...... hiện toàn bộ
Wnt affects symmetry and morphogenesis during post-embryonic development in colonial chordates
EvoDevo - Tập 6 - Trang 1-13 - 2015
Alessandro Di Maio, Leah Setar, Stefano Tiozzo, Anthony W De Tomaso
Wnt signaling is one of the earliest and most highly conserved regulatory pathways for the establishment of the body axes during regeneration and early development. In regeneration, body axes determination occurs independently of tissue rearrangement and early developmental cues. Modulation of the Wnt signaling in either process has shown to result in unusual body axis phenotypes. Botryllus schlos...... hiện toàn bộ
