A cis-Regulatory Signature in Ascidians and Flies, Independent of Transcription Factor Binding Sites
BACKGROUND Transcription initiation is controlled by cis-regulatory modules. Although these modules are usually made of clusters of short transcription factor binding sites, a small minority of such clusters in the genome have cis-regulatory activity. This paradox is currently unsolved. RESULTS To identify what discriminates active from inactive clusters, we focused our attention on short top...
متن کاملAn Otx/Nodal Regulatory Signature for Posterior Neural Development in Ascidians
In chordates, neural induction is the first step of a complex developmental process through which ectodermal cells acquire a neural identity. In ascidians, FGF-mediated neural induction occurs at the 32-cell stage in two blastomere pairs, precursors respectively of anterior and posterior neural tissue. We combined molecular embryology and cis-regulatory analysis to unveil in the ascidian Ciona ...
متن کاملNonindigenous Ascidians in Tropical Waters1
Ascidians (invertebrate chordates) are abundant in many ports around the world. Most of them are nonindigenous species that tolerate wide fluctuations in temperature, salinity, and even pollution. These sessile suspension feeders have a rapid growth rate, usually a short life span of a few months, reach sexual maturity when only a few weeks old, and produce large numbers of shortlived nonfeedin...
متن کاملDevelopmental mode influences diversification in ascidians.
Ascidian species (Tunicata: Ascidiacea) usually have tailed, hatching tadpole larvae. In several lineages, species have evolved larvae that completely lack any tail tissues and are unable to disperse actively. Some tailless species hatch, but some do not hatch before going through metamorphosis. We show here that ascidian species with the highest speciation rates are those with the largest rang...
متن کاملFertilization and sperm chemotaxis in ascidians.
Prior to fertilization, spermatozoa of many animals and plants show chemotactic behavior toward eggs. Chemotactic behavior was first described in ferns (1), and their attractant was identified as the bimalate ion (2). In animals, sperm chemotaxis to the egg was first observed in the hydrozoan Spirocodon saltatrix (3) and is now widely recognized in all species from cnidarians to human (for revi...
