The evolution of chloroplast RNA editing. (1/14)

RNA editing alters the nucleotide sequence of an RNA molecule so that it deviates from the sequence of its DNA template. Different RNA-editing systems are found in the major eukaryotic lineages, and these systems are thought to have evolved independently. In this study, we provide a detailed analysis of data on C-to-U editing sites in land plant chloroplasts and propose a model for the evolution of RNA editing in land plants. First, our data suggest that the limited RNA-editing system of seed plants and the much more extensive systems found in hornworts and ferns are of monophyletic origin. Further, although some eukaryotic editing systems appear to have evolved to regulate gene expression, or at least are now involved in gene regulation, there is no evidence that RNA editing plays a role in gene regulation in land plant chloroplasts. Instead, our results suggest that land plant chloroplast C-to-U RNA editing originated as a mechanism to generate variation at the RNA level, which could complement variation at the DNA level. Under this model, many of the original sites, particularly in seed plants, have been subsequently lost due to mutation at the DNA level, and the function of extant sites is merely to conserve certain codons. This is the first comprehensive model for the evolution of the chloroplast RNA-editing system of land plants and may also be applicable to the evolution of RNA editing in plant mitochondria.  (+info)

XET activity is found near sites of growth and cell elongation in bryophytes and some green algae: new insights into the evolution of primary cell wall elongation. (2/14)

BACKGROUND AND AIMS: In angiosperms xyloglucan endotransglucosylase (XET)/hydrolase (XTH) is involved in reorganization of the cell wall during growth and development. The location of oligo-xyloglucan transglucosylation activity and the presence of XTH expressed sequence tags (ESTs) in the earliest diverging extant plants, i.e. in bryophytes and algae, down to the Phaeophyta was examined. The results provide information on the presence of an XET growth mechanism in bryophytes and algae and contribute to the understanding of the evolution of cell wall elongation in general. METHODS: Representatives of the different plant lineages were pressed onto an XET test paper and assayed. XET or XET-related activity was visualized as the incorporation of fluorescent signal. The Physcomitrella genome database was screened for the presence of XTHs. In addition, using the 3' RACE technique searches were made for the presence of possible XTH ESTs in the Charophyta. KEY RESULTS: XET activity was found in the three major divisions of bryophytes at sites corresponding to growing regions. In the Physcomitrella genome two putative XTH-encoding cDNA sequences were identified that contain all domains crucial for XET activity. Furthermore, XET activity was located at the sites of growth in Chara (Charophyta) and Ulva (Chlorophyta) and a putative XTH ancestral enzyme in Chara was identified. No XET activity was identified in the Rhodophyta or Phaeophyta. CONCLUSIONS: XET activity was shown to be present in all major groups of green plants. These data suggest that an XET-related growth mechanism originated before the evolutionary divergence of the Chlorobionta and open new insights in the evolution of the mechanisms of primary cell wall expansion.  (+info)

Contribution of genosystematics to current concepts of phylogeny and classification of bryophytes. (3/14)

This paper is a survey of the current state of molecular studies on bryophyte phylogeny. Molecular data have greatly contributed to developing a phylogeny and classification of bryophytes. The previous traditional systems of classification based on morphological data are being significantly revised. New data of the authors are presented on phylogeny of Hypnales pleurocarpous mosses inferred from nucleotide sequence data of the nuclear DNA internal transcribed spacers ITS1-2 and the trnL-F region of the chloroplast genome.  (+info)

Anthocerotophyta is a division that includes hornworts, which are non-vascular land plants. These plants are characterized by the presence of specialized cells called mucilage cells and unique reproductive structures called anthoceros-type sporangia. The gametophyte generation is dominant in the life cycle of these plants, and they typically grow in damp, shaded habitats. Some common examples of hornworts include species in the genera Anthoceros, Notothylas, and Phaeoceros.

Acoelomorphs resemble flatworms in many respects, but have a simpler anatomy, not even having a gut. Like flatworms, they have no circulatory or respiratory systems, but they also lack an excretory system. They lack body cavities (acoelomate structure), a hindgut or an anus.[1] The epidermal cells of acoelomorphs are unable to proliferate, a feature that is only shared with rhabditophoran flatworms and was for some time considered a strong evidence for the position of Acoelomorpha within Platyhelminthes. In both groups, the epidermis is renewed from mesodermal stem cells.[29] The nervous system of acoelomorphs is formed by a set of longitudinal nerve bundles beneath the ciliated epidermis. Close to the anterior end, these bundles are united by a ring commissure, but do not form a true brain, although it is hypothesized that such organization was the precursor of the cephalization of the nerve system in more derived bilaterians.[30] After decapitation, such a "brain" (rather, a cerebroid ...
