Research on endangered species is important for species conservation. Some lines of conservation research require tissue or fluids so that molecular data can be obtained. Thus, there is an increasing demand for methods of DNA sampling in endangered species that minimize harm to live animals. This especially concerns such highly threatened and prote...

The taxonomy of the Mediterranean Aristolochia pallida complex has been under debate since several decades with the following species currently recognized: A. pallida, A. lutea, A. nardiana, A. microstoma, A. merxmuelleri, A. croatica, and A. castellana. These taxa are distributed from Iberia to Turkey. To reconstruct phylogenetic and biogeographic...

Significance Membrane fusion is a fundamental process of eukaryotic cells required for subcellular organization and cell–cell communication, involving SNARE proteins and regulatory Sec1/Munc18 (SM) proteins. In plant cytokinesis, membrane vesicles delivered to the cell-division plane fuse with one another to form the partitioning membrane, which re...

Background and aims – The genus Hebelomina was established in 1935 by Maire to accommodate the new species Hebelomina domardiana, a white-spored mushroom resembling a pale Hebeloma in all aspects other than its spores. Since that time a further five species have been ascribed to the genus and one similar species within the genus Hebeloma. In total,...

Membrane vesicles delivered to the cell-division plane fuse with one another to form the partitioning membrane during plant cytokinesis, starting in the cell center. In Arabidopsis, this requires SNARE complexes involving the cytokinesis-specific Qa-SNARE KNOLLE. However, cytokinesis still occurs in knolle mutant embryos, suggesting contributions f...

Extinction of biodiversity due to human activities is a severe global problem. In Europe, however, only a few plant species died out so far. We investigated a dubious, disregarded taxon—Saxifraga oppositifolia subsp. amphibia—which became extinct in the 1960s. It exclusively occurred in a specific niche, namely in seasonally flooded waterside bank...

Cytokinesis separates the forming daughter cells. Higher plants have lost the ability to constrict the plasma membrane (PM) in the division plane. Instead, trans-Golgi network (TGN)-derived membrane vesicles are targeted to the centre of the division plane and generate, by homotypic fusion, the partitioning membrane named cell plate (CP). The CP ex...

Localization of vesicle trafficking markers. This table summarizes the localization of different vesicle trafficking markers without BFA (1th column) and with BFA in wild-type (Col; 2th column), big3 (3th column), BFA-resistant GNOM (GNR; 4th column) and BFA-resistant GNOM in big3 mutant background (GNR big3; 5th column). Abbreviations: PM, plasma...

Recent studies suggest that plants secrete a large number of proteins and peptides into the extracellular space. Secreted proteins play a crucial role in stress response, communication and development of organisms. Here we review the current knowledge of the secretome of more than ten plant species, studied in natural conditions or during (a)biotic...

Membrane fusion is mediated by SNARE complexes. Although membrane fusion is required for separating daughter cells in eukaryotic cytokinesis, SNARE complexes involved are not known. In plants, membrane vesicles targeted to the cell division plane fuse with one another to form the partitioning membrane, progressing from the center to the periphery o...

Membrane fusion is mediated by soluble N-ethylmaleimide–sensitive factor attachment protein receptor (SNARE) complexes. Although membrane fusion is required for separating daughter cells in eukaryotic cytokinesis, the SNARE complexes involved are not known. In plants, membrane vesicles targeted to the cell division plane fuse with one another to fo...

A total of 35 population samples of the liverwort genera Aneura (A. pinguis) and Riccardia (R. latifrons, R. multifida, and R. palmata) were sampled from diverse habitats and geographical provenances in Germany, Austria, and Switzerland. Light and transmission electron microscopy were used to characterise the morphological features of the associati...

Phylogenetic relationships of Sebacinales based on maximum likelihood analysis of partial nuclear-encoded ribosomal large subunit sequences. Color boxes indicate type of symbiosis. Sequences from fruitbodies or cultures that can be assigned to morphospecies are in bold. Circled numbers highlight sequences or clades that are mentioned in the article...

Analytical sample-based rarefaction curve of endophytic Sebacinales, derived from partial nuclear-encoded ribosomal large subunit sequences. Sequences are treated as samples, sequences of ≥99% similarity were assigned to the same sequence type. Confidence intervals are based on 1000 replicates. As the curve is still far from its saturation level, m...

Host plants from which endophytic Sebacinales were sequenced for this study and assignment to plant families. Sequences marked with an asterisk are from herbarium specimens collected in the 1830/40s by G.W. Schimper and T. Kotschy. (XLS)

Map of primers used for PCR and sequencing in the present study. The map is based on GenBank sequences AY505557 and DQ520096, primer lengths are not drawn to scale. The ruler gives number of base pairs, starting from the 5′ end of primer NS13. (PDF)

Inconspicuous basidiomycetes from the order Sebacinales are known to be involved in a puzzling variety of mutualistic plant-fungal symbioses (mycorrhizae), which presumably involve transport of mineral nutrients. Recently a few members of this fungal order not fitting this definition and commonly referred to as 'endophytes' have raised considerable...
