The discovery of arbuscules in Aglaophyton major, an Early Devonian land plant, provides unequivocal evidence that mycorrhizae were established >400 million years ago. Nonseptate hyphac and occur a specialized meristematic region the cortex continually provided new cells for fungal infection. Arbuscules are morphologically identical to those living arbuscular consisting basal trunk repeatedly branched bush-like tuft within plant cell. Although interpretations evolution mycorrhizal...

The Early Devonian Rhynie chert has been critical in documenting early land plant-fungal interactions. However, complex associations involving several fungi that enter into qualitatively different relationships with a single host plant and even interact one another have not yet detailed. Here, we studied petrographic thin sections of the Nothia aphylla. Three fungal endophytes (co)occur prostrate axes this plant: narrow hyphae producing clusters small spores; large spherical...

AbstractThe 400 million-year-old Rhynie chert has provided a wealth of information not only early land plants, but also the fungi that inhabited this paleoecosystem. In paper we report first unequivocal evidence arbuscules in an endomycorrhizal symbiosis. A new genus, Glomites, is characterized by extraradical, aseptate hyphae with two-parted wall, and intraradical, highly branched network thin-walled hyphae. Hyphal branches produce terminal, elongate-globose multilayered spores lack basal...

We describe a perithecial, pleomorphic ascomycetous fungus from the Early Devonian (400 mya) Rhynie chert; occurs in cortex just beneath epidermis of aerial stems and rhizomes vascular plant Asteroxylon. Perithecia are nearly spherical with short, ostiolate neck that extends into substomatal chamber host plant; periphyses line inner surface ostiole. The ascocarp wall is multilayered formed septate hyphae; extending elongate asci interspersed delicate paraphyses. Asci appear to be unitunicate...

In this essay we examine the fossil record of land plants, focusing on late Paleozoic. We explore nature in terms what is preserved, where, why and with biases. And as a consequence, how it can be used to answer questions posed at various spatial temporal scales, cautions must consider when interpreting it, surprises may hold. Generally speaking, terrestrial plants rich reveals clear directional trends phenotypic complexity, biodiversity, ecosystem organization. It also has reasonably well...

Late Permian seed-plant evolution The great evolutionary expansion of seed plants took place in the Mesozoic era, which began after mass extinction 252 million years ago. Blomenkemper et al. report discovery fossils from (252-million- to 260-million-year-old) deposits on margins Dead Sea Jordan. This area represents an equatorial habitat with pronounced dry seasons. These fossils, include earliest records conifers, push back ages several important lineages. Some these lineages appear span...

Our three-dimensional modelling fine structures, based on assembling successive images made at different focal planes through translucent chert matrix, revealed for first time trabeculae: tiny cuticular pillars separating adjacent lung lamellae and creating permanent air space.

Abstract Nematodes are one of the most abundant groups invertebrates on face earth. Their extremely poor fossil record hinders our ability to assess just when members this group invaded land and first became associated with plants. This study reports nematodes from stomatal chambers Early Devonian (396 mya) plant, Aglaophyton major. These nematodes, which tentatively assigned order Enoplia, described as Palaeonema phyticum gen. n., sp. n. in new family Palaeonematidae fam. Diagnostic...
