Rrna Sequences

Nearly complete 16S ribosomal RNA (rRNA) sequences were determined for fully characterised axenic strains of Thiothrix, Eikelboom type O21N, and Eikelboom type 1701 originally isolated from bulking activated sludges. Thiothrix strains formed a monophyletic group (100% bootstrap support) with previously described Thiothrix nivea strain JP2 and Thiothrix ramosa. Eikelboom type O21N strain AP3 revealed a sufficiently strong relationship to the Thiothrix group to suggest a common ancestry for the two organism although it was not possible to designate type 021N as a species of Thiothrix. Eikelboom type 1701 contained within its sequence the target sequence of an oligonucleotide probe for the detection of Sphaerotilus natans.

The forebrain plays a critical role in a broad range of neural processes encompassing sensory integration and initiation/selection of behaviour. The forebrain functions through an interaction between different cortical areas, the thalamus, the basal ganglia with the dopamine system, and the habenulae. The ambition here is to compare the mammalian forebrain with that of the lamprey representing the oldest now living group of vertebrates, by a review of earlier studies. We show that the lamprey dorsal pallium has a motor, a somatosensory, and a visual area with retinotopic representation. The lamprey pallium was previously thought to be largely olfactory. There is also a detailed similarity between the lamprey and mammals with regard to other forebrain structures like the basal ganglia in which the general organisation, connectivity, transmitters and their receptors, neuropeptides, and expression of ion channels are virtually identical. These initially unexpected results allow for the possibility that many aspects of the basic design of the vertebrate forebrain had evolved before the lamprey diverged from the evolutionary line leading to mammals. Based on a detailed comparison between the mammalian forebrain and that of the lamprey and with due consideration of data from other vertebrate groups, we propose a compelling account of a pan-vertebrate schema for basic forebrain structures, suggesting a common ancestry of over half a billion years of vertebrate evolution.
