Occurrence and levels of micropollutants across environmental and engineered compartments in Austria.

J Environ Manage 2018 Dec 3;232:636-653. Epub 2018 Dec 3.

Institute for Water Quality and Resource Management, TU Wien, Karlsplatz 13/226, 1040, Vienna, Austria.

Occurrence and concentration of a broad spectrum of micropollutants are investigated in Austrian river catchments, namely polycyclic aromatic hydrocarbons (PAHs), polybrominated diphenyl ethers (PBDEs), organotin compounds, perfluoroalkyl acids (PFAAs) and metals. The parallel analysis across multiple environmental and engineered compartments sheds light on the ratio of dissolved and particulate transport and on differences in concentration levels between point and diffuse emission pathways. It is found that some PAHs and organotins are present in rivers, groundwater and bulk deposition at higher concentrations than in municipal wastewater effluents. Read More

Daily energy expenditure of males following alternative reproductive tactics: Solitary roamers spend more energy than group-living males.

Physiol Behav 2018 Dec 3. Epub 2018 Dec 3.

School of Animal, Plant & Environmental Sciences, University of the Witwatersrand, Private Bag 3, WITS, 2050 Johannesburg, South Africa; IPHC, UNISTRA, CNRS, 23 rue du Loess, 67200 Strasbourg, France.

In many species, males follow alternative reproductive tactics (ARTs), where one tactic (called bourgeois) has much higher reproductive success than alternative tactics followed by males with lower competitive ability. The extent to which ARTs differ in energetic costs is unknown, but it is important to understand the fitness payoffs of ARTs. We studied male African striped mice (Rhabdomys pumilio) which follow one of three ARTs: heavy bourgeois males defend harems of females and have 10 times higher reproductive success than smaller roamers, which have ten times higher reproductive success than philopatric males, which remain in their natal group and are the smallest males.

Norwich Medical School, University of East Anglia, Norwich Research Park, Norwich, Norfolk, UK, NR4 7TJ.

Background: Researchers have suggested that omega-3 polyunsaturated fatty acids from oily fish (long-chain omega-3 (LCn3), including eicosapentaenoic acid (EPA) and docosahexaenoic acid (DHA)), as well as from plants (alpha-linolenic acid (ALA)) benefit cardiovascular health. Guidelines recommend increasing omega-3-rich foods, and sometimes supplementation, but recent trials have not confirmed this.

An RK/ST C-terminal Motif is Required for Targeting of OEP7.2 and a Subset of Other Arabidopsis Tail-Anchored Proteins to the Plastid Outer Envelope Membrane.

Plant Cell Physiol 2018 Dec 5. Epub 2018 Dec 5.

Department of Molecular and Cellular Biology, University of Guelph, Guelph, Ontario, Canada.

Tail-anchored (TA) proteins are a unique class of integral membrane proteins that possess a single C-terminal transmembrane domain and target post-translationally to the specific organelles at which they function. While significant advances have been made in recent years in elucidating the mechanisms and molecular targeting signals involved in the proper sorting of TA proteins, particularly to the endoplasmic reticulum and mitochondria, relatively little is known about the targeting of TA proteins to the plastid outer envelope. Here we show that several known or predicted plastid TA outer envelope proteins (OEPs) in Arabidopsis possess a C-terminal RK/ST sequence motif that serves as a conserved element of their plastid targeting signal.

miRDeep-P2: accurate and fast analysis of the microRNA transcriptome in plants.

Bioinformatics 2018 Dec 6. Epub 2018 Dec 6.

Beijing Agro-biotechnology Research Center, Beijing Academy of Agriculture and Forestry Sciences, Beijing, P. R. China.

Motivation: Two major challenges arise when employing next generation sequencing (NGS) methods to comprehensively identify microRNAs (miRNAs) in plants: 1) how to minimize the false-positive inheritable to computational predictions; 2) how to minimize the computational time required for analyzing the miRNA transcriptome in plants with complex and large genomes.

Results: We updated miRDeep-P to miRDeep-P2 (miRDP2) by employing a new filtering strategy and overhauling the algorithm. miRDP2 has been tested against miRNA transcriptomes in plants with increasing genome sizes that included Arabidopsis, rice, tomato, maize and wheat. Read More

Computer vision-based phenotyping for improvement of plant productivity: A machine learning perspective.

Gigascience 2018 Dec 6. Epub 2018 Dec 6.

Department of Information Engineering and Computer Science, University of Trento, Via Sommarive 9, 38123 Trento, Italy.

Employing computer vision to extract useful information from images and videos is becoming a key technique for identifying phenotypic changes in plants. In this report, we review the emerging aspects of computer vision for automated plant phenotyping. Recent advances in image analysis empowered by machine learning-based techniques, including convolutional neural network-based modeling, have expanded their application to assist high-throughput plant phenotyping.

Associations Between Drosophila suzukii (Diptera: Drosophilidae) and Fungi in Raspberries.

Environ Entomol 2018 Dec 4. Epub 2018 Dec 4.

Department of Entomology, University of Maryland, College Park, MD.

The invasive vinegar fly, Drosophila suzukii Matsumura, has emerged as one of the most serious arthropod pests of primocane red raspberries (Rubus ideaus L.) in the United States. In raspberries, D. Read More

Protein-protein interaction sites prediction by ensemble random forests with synthetic minority oversampling technique.

Bioinformatics 2018 Dec 5. Epub 2018 Dec 5.

Bioinformatics and Mathematical Biosciences Lab, Department of Agronomy, Horticulture and Plant Science, South Dakota State University, Brookings, SD, USA.

Motivation: The prediction of protein-protein interaction (PPI) sites is a key to mutation design, catalytic reaction, and the reconstruction of PPI networks. It is a challenging task considering the significant abundant sequences and the imbalance issue in samples.

Results: A new ensemble learning based method, EL-SMURF, was proposed for PPI sites prediction in this study. Read More

Protein gradients on the nucleoid position the carbon-fixing organelles of cyanobacteria.

Elife 2018 Dec 6;7. Epub 2018 Dec 6.

Department of Biochemistry, Michigan State University, East Lansing, United States.

Carboxysomes are protein-based bacterial organelles encapsulating key enzymes of the Calvin-Benson-Bassham cycle. Previous work has implicated a ParA-like protein (hereafter McdA) as important for spatially organizing carboxysomes along the longitudinal axis of the model cyanobacterium PCC 7942. Yet, how self-organization of McdA emerges and contributes to carboxysome positioning is unknown. Read More

Request for revision of the Statutes of the International Committee on Systematics of Prokaryotes.

Int J Syst Evol Microbiol 2018 Dec 6. Epub 2018 Dec 6.

6​National Research Council of Italy, Institute of Ecosystem Study, I-50019 Sesto Fiorentino, Italy.

At the Valencia Plenary meeting on 7-9 July, 2017, the Working Group on the organization and structure of the ICSP recommended amendment of the Statutes of the ICSP (Dijkshoorn L. Int J Syst Evol Microbiol 2018; 68: 2104-2110). In October 2017, our Executive-Secretary, Lenie Dijkshoorn, sent out a call for participation in this working group, which began work in December, 2017. Read More

Desikacharya gen. nov., a phylogenetically distinct genus of Cyanobacteria along with the description of two new species, Desikacharya nostocoides sp. nov. and Desikacharya soli sp. nov., and reclassification of Nostoc thermotolerans to Desikacharya thermotolerans comb. nov.

Two Nostoc-like strains have been isolated, purified, cultured and identified on the basis of the polyphasic approach using morphological, ecological, molecular and phylogenetic methods. Both strains were found to have morphology similar to the genus Nostoc, but clustered strongly in a group distant from the Nostocsensu stricto clade. Further analysis, using the folded structures of the 16S-23S ITS region revealed strong differences from closely related members of the genus Nostoc. Read More
