Pattern and process in the evolution of the sole dioecious member of BrassicaceaeEvoDevo - 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 mutationsEvoDevo - 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
Spatial and temporal patterns of gene expression during neurogenesis in the sea urchin Lytechinus variegatusEvoDevo - Tập 10 - Trang 1-16 - 2019
Leslie A. Slota, Esther M. Miranda, David R. McClay
The sea urchin is a basal deuterostome that is more closely related to vertebrates than many organisms traditionally used to study neurogenesis. This phylogenetic position means that the sea urchin can provide insights into the evolution of the nervous system by helping resolve which developmental processes are deuterostome innovations, which are innovations in other clades, and which are ancestra...... hiện toàn bộ
Sex-specific and developmental expression of Dmrt genes in the starlet sea anemone, Nematostella vectensisEvoDevo - 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
Locomotory control in amphioxus larvae: new insights from neurotransmitter dataEvoDevo - Tập 8 - Trang 1-8 - 2017
Thurston Lacalli, Simona Candiani
Amphioxus larvae have a midbrain-level locomotory control center whose overall organization is known from serial TEM reconstructions. How it functions has been a puzzle, owing to uncertainty as to the transmitters used by each class of neurons, but this has recently become clearer. We summarize what is now known, and correct past misconceptions: The large paired neurons at the core of the control ...... hiện toàn bộ
