“…In contrast to the histone m R N A of higher plants, the histone mRNAs of Volvox, a lower plant, are reported not to be polyadenylated and to be terminated at the 3' end by palindrome (a stem and loop structure) regulating probably by a mechanism similar to the one operating in animals [18]. end of the cDNA.…”

Screening of a lambda gt11 cDNA expression library of Euglena gracilis with antibodies directed against histones H2 from maize resulted in the isolation of a full-length cDNA for a histone H2A. The open-reading frame of 408 bp corresponded to a protein of 136 amino acid residues (14 kDa). Despite the presence of a poly(A) tail, which is typical of plant histone mRNA but not of animal histone mRNA, the size of the deduced protein and its percentage of homology were closer to animal histone H2As than to plant or lower eukaryotic histone H2A. Sequence alignment revealed that the Euglena H2A protein was characterized by a shorter C-terminus and a N-terminus which extended 10 residues past the animal H2A. In contrast to other organisms studied, the expression of the Euglena H2A gene appeared to be almost constant during an entire life-cycle and presented no cell-stage-specific expression during development. Similar results are obtained for another histone gene, H3, and for beta-tubulin. Regulation of gene expression at a post-transcriptional level seems to be a general feature of Euglena.

“…For example, in both Volvox carterae (Muller and Schmitt 1988;Muller et al 1990) and yeast (Hereford et al 1979;Smith and Andresson 1983) the histone genes are organized as opposed (H3/H4 and H2A/H2B) pairs, and opposed H3/H4 gene pairs have been found in a number of ciliates. (See Brunk et al 1990 and references therein.)…”

“…3B). Although the case for using this feature as a criterion of "metazoan-ness" appears to be weakened by the presence of 3'-palindromes associated with the histone genes of Volvox carterae (Muller and Schmitt 1988;Muller et al 1990), in fact this is likely to be a case of convergence.

Nucleotide sequence of the histone gene cluster in the coral acropora formosa (cnidaria; scleractinia): Features of histone gene structure and organization are common to diploblastic and triploblastic metazoans

et al. 1993

We report the nucleotide sequence of the core histone gene cluster from the Cnidarian Acropora formosa. This is the first histone gene cluster to be sequenced from a diploblastic organism and the predicted amino acid sequences most resemble those of sea urchin equivalents. Each of the Cnidarian histone genes has two conserved regions 3' of the coding sequences and these closely resemble those of the metazoan alpha-class histone genes. In A. formosa the core histone genes are arranged as opposed (H3/H4 and H2A/H2B) pairs, a pattern common to the nondeuterostome metazoa, and tandem repetition is the predominant pattern of organization in the Cnidarian. With the recent identification of several classes of homeobox genes in Cnidarians these features clearly align the Cnidaria with triploblastic metazoans, supporting a monophyletic origin of the metazoa.

“…Divergently transcribed gene pairs of histone genes H3 and H4 and H2A and H2B are found in different eukaryotes, e.g., Volvox carteri (Müll-er and Schmidt 1988;Müller et al 1990), Saccharomyces cerevisiae (Smith and Andrésson 1983), and in all metazoa, except for the deuterostomes (see Miller et al 1993).…”

The histones H4 are known as highly conserved proteins. However, in ciliates a high degree of variation was found compared both to other eukaryotes and between the ciliate species. To date, only H4 histones of species belonging to two distantly related classes have been investigated. In order to obtain more detailed information on histone H4 variation in ciliates we undertook a comprehensive sequence analysis of PCR-amplified internal H4 fragments from 12 species belonging to seven out of the nine currently recognized ciliate classes. In addition, we used PCR primers to amplify longer fragments of H3 and H4 genes including the intergenic region. The encoded amino acid sequences reveal a high number of differences when compared with those of other eukaryotes and the ciliate species investigated. Furthermore, in some species H4 gene variants were detected, which result in amino acid differences. The greatest number of substitutions and insertions found was in the amino terminal region of the H4 histones. However, all sequences possess a conserved region corresponding to those of all other eukaryotic H4 histones. The histone gene variations were used to reconstruct phylogenetic relationships. The tree from our data matches perfectly with the ribosomal RNA data: The heterotrichs, which were considered as a late branching lineage, diverge at the base of the ciliate tree and groups formerly thought to represent ancestral lineages now appear as highly derived ciliates.
