Ebf Activates Expression of a Cholinergic Locus in a Multipolar Motor Ganglion Interneuron Subtype in Ciona

open access: yesFrontiers in Neuroscience, 2021
Conserved transcription factors termed “terminal selectors” regulate neuronal sub-type specification and differentiation through combinatorial transcriptional regulation of terminal differentiation genes.

The Hydrocoel and the Ancestry of the Chordates [PDF]

open access: yesEvolution, 1965
Several traits shared by the tornarian larva of the Enteropneusta and certain larval forms of the Echinodermata, including a transparent body, bilaterality, the arrangement of undulating bands of cilia, and a pelagic existence, are well known to biologists as a whole.

Evidence for dynamic and multiple roles for huntingtin in Ciona intestinalis [PDF]

open access: yes, 2013
Although mutations in the huntingtin gene (HTT) due to poly-Q expansion cause neuropathology in humans (Huntington’s disease; HD), the normal function(s) of the gene and its protein (HTT) remain obscure.

Improved Understanding of the Role of Gene and Genome Duplications in Chordate Evolution With New Genome and Transcriptome Sequences

open access: yesFrontiers in Ecology and Evolution, 2021
Comparative approaches to understanding chordate genomes have uncovered a significant role for gene duplications, including whole genome duplications (WGDs), giving rise to and expanding gene families.

The Genome of Amphioxus and the Ancestral Proto-chordate [PDF]

open access: yes, 2006
Lancelets ("amphioxus") are the modern survivors of an ancient chordate lineage, the cephalochordates, with a fossil record dating back to the Cambrian.

Neuronal patterning of the tubular collar cord is highly conserved among enteropneusts but dissimilar to the chordate neural tube

open access: yesScientific Reports, 2017
A tubular nervous system is present in the deuterostome groups Chordata (cephalochordates, tunicates, vertebrates) and in the non-chordate Enteropneusta.

Isolation of key retinoid signalling and metabolic modules in invertebrates

open access: yesFrontiers in Marine Science, 2014
Retinoids are a class of molecules related to vitamin A (Retinol) that are required for regulation of critical chordate ndocrine-mediated process, such as embryonic development, reproduction, and vision.

Evolution of Somite Compartmentalization: A View From Xenopus

open access: yesFrontiers in Cell and Developmental Biology, 2022
Somites are transitory metameric structures at the basis of the axial organization of vertebrate musculoskeletal system. During evolution, somites appear in the chordate phylum and compartmentalize mainly into the dermomyotome, the myotome, and the ...
