The missing link between zeolites and polyoxometalates.

ABSTRACT: Open framework materials such as zeolites and metalorganic frameworks are garnering tremendous interest because of their intriguing architecture and attractive functionalities. Thus, new types of open framework materials are highly sought after. Here, we present the discovery of completely new inorganic framework materials, where, in contrast to conventional inorganic open frameworks, the scaffold is not based on tetrahedral EO₄ (E = main group element) but octahedral MO₆ (M = transition metal) building blocks. These structural features place them closer to polyoxometalates than zeolites. The first representatives of this class of materials are [(R)₂₄(NH₄)₁₄(PO(OH)₂)₆]·[M₁₃₄(PO₃(OH,F))₉₆F₁₂₀] (M = Co, R = C₂Py = 1-ethylpyridinium and M = Ni, R = C₄C₁Py = 1-butyl-3-methylpyridinium) featuring interlinked fullerene-like nanosphere cavities. Having a transition metal building up the framework brings about interesting properties, for example, spin-glass behavior, and, with this particular topology, a hedgehog-like spin orientation.

Project description:The origin and deep evolution of retroviruses remain largely unclear. It has been proposed that retroviruses might have originated from a Ty3/Gypsy retrotransposon, but all known Ty3/Gypsy retrotransposons are only distantly related to retroviruses. Retroviruses and some plant Athila/Tat elements (within Ty3/Gypsy retrotransposons) independently evolved a dual RNase H domain and an env/env-like gene. Here, we reported the discovery of a novel lineage of retrotransposons, designated Odin retrotransposons, in the genomes of eight sea anemones (order Actinaria) within the Cnidaria phylum. Odin retrotransposons exhibited unique genome features, encoding a dual RNase H domain (like retroviruses) but no env gene (like most Ty3/Gypsy retrotransposons). Phylogenetic analyses based on reverse transcriptase showed that Odin retrotransposons formed a sister group to lokiretroviruses, and lokiretroviruses and Odin retrotransposons together were sister to canonical retroviruses. Moreover, phylogenetic analyses based on RNase H and integrase also supported the hypothesis that Odin retrotransposons were sisters to lokiretroviruses. Lokiretroviruses and canonical retroviruses did not form a monophyletic group, indicating that lokiretroviruses and canonical retroviruses might represent two distinct virus families. Taken together, the discovery of Odin retrotransposons narrowed down the evolutionary gaps between retrotransposons and canonical retroviruses and lokiretroviruses. IMPORTANCE The origin of retroviruses remains largely unclear. In this study, we discovered a novel retrotransposon lineage, Odin retrotransposons, within the genomes of sea anemones (order Actinaria). In contrast to retroviruses and most retrotransposons, Odin retrotransposons encode a dual RNase H domain but no env gene. Phylogenetic analyses showed that Odin retrotransposons were sisters to lokiretroviruses, and lokiretroviruses and Odin retrotransposons were sisters to retroviruses, establishing an evolutionary framework to decipher the origin of retroviruses (canonical retroviruses and lokiretroviruses). Our results provided insights into the diversity and deep evolution of LTR retrotransposons closely related to retroviruses.

Project description:BackgroundFunctional traits are the primary biotic component driving organism influence on ecosystem functions; in consequence, traits are widely used in ecological research. However, most animal trait-based studies use easy-to-measure characteristics of species that are at best only weakly associated with functions. Animal-mediated pollination is a key ecosystem function and is likely to be influenced by pollinator traits, but to date no one has identified functional traits that are simple to measure and have good predictive power.MethodsHere, we show that a simple, easy to measure trait (hairiness) can predict pollinator effectiveness with high accuracy. We used a novel image analysis method to calculate entropy values for insect body surfaces as a measure of hairiness. We evaluated the power of our method for predicting pollinator effectiveness by regressing pollinator hairiness (entropy) against single visit pollen deposition (SVD) and pollen loads on insects. We used linear models and AICC model selection to determine which body regions were the best predictors of SVD and pollen load.ResultsWe found that hairiness can be used as a robust proxy of SVD. The best models for predicting SVD for the flower species Brassica rapa and Actinidia deliciosa were hairiness on the face and thorax as predictors (R2 = 0.98 and 0.91 respectively). The best model for predicting pollen load for B. rapa was hairiness on the face (R2 = 0.81).DiscussionWe suggest that the match between pollinator body region hairiness and plant reproductive structure morphology is a powerful predictor of pollinator effectiveness. We show that pollinator hairiness is strongly linked to pollination-an important ecosystem function, and provide a rigorous and time-efficient method for measuring hairiness. Identifying and accurately measuring key traits that drive ecosystem processes is critical as global change increasingly alters ecological communities, and subsequently, ecosystem functions worldwide.
