“…5 Mya, using six combinations of fossil calibration(Cardinal-McTeague et al 2016). Even in the fossil-rich genus of Previous estimates of early land plant divergences from chronograms have been a subject of much debate, as they tend to extend into the time before the known date for the earliest land plant (475 Mya;Bowles et al, 2022;Graur & Martin, 2004;Harris et al, 2022;Morris et al, 2018). Our estimate of the origin of Metzgeriidae also experienced a similar issue of a wide HPD interval, likely due to the small number of fossils.…”

Aneuraceae is the largest family of the simple thalloid liverworts. Despite simple morphological features, this family is well-known for its unique ecology, cryptic diversity, and species-rich lineages. In this study, we explored the evolutionary history and diversification of the Aneuraceae. Investigating the effects of fossil calibrations on divergence time estimates and how recognizing cryptic species impacts macroevolutionary analyses. We used publicly available nucleotide sequences to reconstruct chronograms of Aneuraceae with representatives from subclass Metzgeriidae as outgroups. We also examined the consequences of different calibrations in chronogram reconstruction. Then, the resulting time-calibrated phylogeny was employed to reveal diversification dynamics with lineage through time plots (LTTPs), γ-statistics, and Bayesian Analysis of Macroevolutionary Mixtures (BAMM). The Aneuraceae had originated and created diversity since the Lower Carboniferous (352.75 Mya, 95%HPD: 505.79–264.59) to Upper Devonian. Lineage diversification of Aneuraceae species was consistent with late bursts of speciation with two significant rate shifts in genus Riccardia: one at the crown node of the genus and the other at the Neotropical clade. Including cryptic taxa resulted in an additional rate shift at the crown node of Aneura. Aneuraceae originated during the middle Palaeozoic Era, similar to other early terrestrial plants, although different fossil calibrations significantly affected the estimation of divergence dating. Two speciation rate shifts in Riccardia could be the results of asexual reproductive structure in this genus and climate changes in the Neotropics. Ecological conditions at the origin of the family and association with fungi might be associated with the increased diversification in this family.

“…Archaeplastida is a potential clade comprised of mainly photosynthetic eukaryotes (Bowles, et al 2022). Archaeplastida formed when an ancestral eukaryote acquired a chloroplast by the primary endosymbiosis of an ancestral cyanobacterium (Ponce-Toledo, et al 2017).…”

“…Since their origin in the paleoproterozoic era about 2 billion years ago, Archaeplastida have greatly shaped the appearance of planet earth (Sánchez-Baracaldo, et al 2017). According to recent classifications there are five divisions of archaeplastida, the rhodophytes (red algae), glaucophytes, Rhodelphidia, Picozoa and Viridiplantae (green plants) (Bowles, et al 2022).…”

“…Within the green plants, the streptophytes are the largest group (Leliaert, et al 2011). The ancestor of streptophytes was most likely multicellular (Bowles, et al 2022) from which unicellular and multicellular species evolved. Streptophytes are comprised of five paraphyletic lineages of streptophyte algae and embryophytes (land plants) (Leliaert, et al 2011).…”

“…Streptophytes are comprised of five paraphyletic lineages of streptophyte algae and embryophytes (land plants) (Leliaert, et al 2011). The streptophyte algae classes Chlorokybophyceae and Mesostigmatophycae form a clade and branched off first, followed by the Klebsormidiophyceae, Charophyceae and the Coleochaetophyceae (Bowles, et al 2022). Streptophyte algae of the class Zygnematophyceae are likely the closest relatives of land plants.…”

Deep evolution of MADS-box genes in Archaeplastida

MADS-box genes represent a paneukaryotic gene family encoding transcription factors. Given its importance for essential functions in plants, animals and fungi, such as development of organ identity and mating type determination, the phylogeny of MADS-box genes is of great biological interest. It has been well established that a gene duplication in the stem group of extant eukaryotes generated two clades of MADS-box genes, termed Type I and Type II genes. Almost all Type II genes of land plants contain a keratin-like (K) domain in addition to the family-defining, DNA-binding MADS (M) domain and are also termed MIKC-type genes. Due to a lack of sampling of MADS-box genes in Archaeplastida (rhodophytes, glaucophytes, chlorophytes, and streptophytes) except land plants, the deep evolution of MADS-box genes in plants remains poorly understood, however. Here we use the genomic and transcriptomic ressources that have become available in recent years to answer longstanding questions of MADS-box gene evolution in Archaeplastida. Our results reveal that archaeplastid algae likely do not harbour Type I MADS-box genes. However, rhodophytes, glaucophytes, prasinodermophytes and chlorophytes possess Type II MADS-box genes without a K domain. Type II MADS-box genes with a K domain are found only in streptophytes. This corroborates previous views that some Type II gene acquired a K domain in the stem group of extant streptophytes, generating MIKC-type genes. Interestingly, we found both variants of Type II genes - with (MIKC) and without a K domain - in streptophyte algae, but not in land plants (embryophytes), suggesting that Type II genes without a K domain (ancestral Type II genes) were lost in the stem group of land plants. Our data reveal that the deep evolution of MADS-box genes in "plants" (Archaeplastida) was more complex than has previously been thought.

Analyzing Mushroom Structural Patterns of a Highly Compressible and Expandable Hemostatic Foam for Gastric Perforation Repair

Nature presents the most beautiful patterns through evolving. Here, a layered porous pattern in golden ratio (0.618) is reported from a type of mushroom ‐Dictyophora Rubrovalvata stipe (DRS). The hierarchical structure shows a mathematical correlation with the golden ratio. This unique structure leads to superior mechanical properties. The gradient porous structure from outside to innermost endows it with asymmetrical hydrophilicity. A mathematical model is then developed to predict and apply to 3D printed structures. The mushroom is then explored to repair gastric perforation because the stomach is a continuous peristaltic organ, and the perforated site is subject to repeated mechanical movements and pressure changes. At present, endoscopic clipping is ineffective in treating ulcerative perforation with fragile surrounding tissues. Although endoscopic implant occlusion provides a new direction for the treatment of gastric ulcers, but the metal or plastic occluder needs to be removed, requiring a second intervention. Decellularized DRS (DDRS) is found with asymmetric water absorption rate, super‐compressive elasticity, shape memory, and biocompatibility, making it a suitable occluder for the gastric perforation. The efficacy in blocking gastric perforation and promoting healing is confirmed by endoscopic observation and tissue analysis during a 2‐month study.
