Improved prediction of the bioconcentration factors of organic contaminants from soils into plant/crop roots by related physicochemical parameters.

Environ Int 2019 Feb 15;126:46-53. Epub 2019 Feb 15.

Department of Civil and Environmental Engineering, The University of Iowa, Iowa City, IA 52242, United States of America.

There has been an on-going pursuit for relations between the levels of chemicals in plants/crops and the source levels in soil or water in order to address impacts of toxic substances on human health and ecological quality. In this research, we applied the quasi-equilibrium partition model to analyze the relations for nonionic organic contaminants between plant/crop roots and external soil/water media. The model relates the in-situ root concentration factors of chemicals from external water into plant/crop roots (RCF) with the system physicochemical parameters and the chemical quasi-equilibrium states with plant/crop roots (α ≤1).

Moving window smoothing on the ensemble of competitive adaptive reweighted sampling algorithm.

Spectrochim Acta A Mol Biomol Spectrosc 2019 Feb 11;214:129-138. Epub 2019 Feb 11.

College of Science, China Agricultural University, Beijing 100193, China.

A novel chemometrical method, named as MWS-ECARS, which is based on using the moving window smoothing upon an ensemble of competitive adaptive reweighted sampling, is proposed as the spectral variable selection approach for multivariate calibration in this study. In terms of elimination of uninformative variables, an ensemble of CARS is carried out first and MWS is then performed to search for effective variables around the high frequency variables. The variable subset with the lowest standard error of cross-validation (SECV) is treated as the optimal threshold and the corresponding moving window width is regarded as the optimal window width.

Addition-omission of zinc, copper, and boron nano and bulk oxide particles demonstrate element and size -specific response of soybean to micronutrients exposure.

Sci Total Environ 2019 Feb 11;665:606-616. Epub 2019 Feb 11.

The Connecticut Agricultural Experiment Station, 123 Huntington Street, New Haven, CT 06511, United States.

Plant response to microelements exposure can be modulated based on particle size. However, studies are lacking on the roles of particle size and specific microelements in mixed exposure systems designed for plant nutrition, rather than toxicology. Here, an addition-omission strategy was used to address particle-size and element-specific effects in soybean exposed to a mixture of nano and bulk scale oxide particles of Zn (2 mg Zn/kg), Cu (1 mg Cu/kg) and B (1 mg B/kg) in soil.

Reversibility of enzymatic reactions might limit biotransformation of organic micropollutants.

Sci Total Environ 2019 Feb 11;665:574-578. Epub 2019 Feb 11.

Department of Chemical Engineering, School of Engineering, Universidade de Santiago de Compostela, Rúa Lope Gómez de Marzoa, E-15782 Santiago de Compostela, Spain. Electronic address:

Biotransformation of many organic micropollutants (OMPs) in sewage treatment plants is incomplete leading to their release into the environment. Recent findings suggest that thermodynamic aspects of the reaction as chemical equilibrium limit biotransformation, while kinetic parameters have a lower influence. Reversibility of enzymatic reactions might result in a chemical equilibrium between the OMP and the transformation product, thus impeding a total removal of the compound. Read More

Investigation of non-community stakeholders regarding community engagement and environmental malodour.

Sci Total Environ 2019 Feb 11;665:546-556. Epub 2019 Feb 11.

UNSW Water Research Centre, School of Civil and Environmental Engineering, University of New South Wales, Sydney, NSW 2052, Australia.

Research into industry-community relationships have focused almost exclusively on the ways in which communities responds to actions from industries. This has led to a paucity of understanding with regards to how community engagement and malodour amelioration practices have been adopted by industry personnel, as well as the attitudes and beliefs of non-community stakeholders in general. In this study, a survey to water industry personnel was distributed to three Australian water utilities in South-Eastern Australia and a semi-structured interview process was carried out with plant managers at six wastewater treatment plants.

Fit-for-purpose modelling of radiocaesium soil-to-plant transfer for nuclear emergencies: a review.

J Environ Radioact 2019 Feb 15;201:58-66. Epub 2019 Feb 15.

Biosphere Impact Studies Unit, The Belgian Nuclear Research Centre, Boeretang 200, Mol, Belgium. Electronic address:

Numerous radioecological models have been developed to predict radionuclides transfer from contaminated soils to the food chain, which is an essential step in preparing and responding to nuclear emergencies. However, the lessons learned from applying these models to predict radiocaesium (RCs) soil-to-plant transfer following the Fukushima accident in 2011 renewed interest in RCs transfer modelling. To help guide and prioritise further research in relation to modelling RCs transfer in terrestrial environments, we reviewed existing models focussing on transfer to food crops and animal fodders.

Genome-wide analysis of flanking sequences reveals that Tnt1 insertion is positively correlated with gene methylation in Medicago truncatula.

Plant J 2019 Feb 18. Epub 2019 Feb 18.

Noble Research Institute, 2510 Sam Noble Parkway, Ardmore, OK, 73401, USA.

From a single transgenic line harboring five Tnt1 transposon insertions, we generated a near-saturated insertion population in Medicago truncatula. Using thermal asymmetric interlaced (TAIL) PCR followed by sequencing, we recovered 388,888 flanking sequence tags (FSTs) from 21,741 insertion lines in this population. FST recovery from 14 Tnt1 lines using the whole genome sequencing and/or Tnt1-capture sequencing approaches suggests an average of 80 insertions per line, which is more than previous estimation of 25 insertions.

Polydimethylsiloxane Replicas Efficacy for Simulating Fresh Produce Surfaces and Application in Mechanistic Study of Colloid Retention.

J Food Sci 2019 Feb 18. Epub 2019 Feb 18.

Dept. of Plant and Soil Sciences, Univ. of Delaware, 450 ISE Lab, 221 Academy Street, Newark, DE, 19716, U.S.A.

Foodborne illnesses associated with fresh produce have attracted increasing attention in the food industry, scientific and public health communities. Studies have shown that surface properties of fresh produce can affect bacterial attachment and colonization, yet the mechanisms involved remain poorly understood. In our previous work, using colloids as bacterial surrogates, we demonstrated that colloid retention on fresh produce was controlled by water retention/distribution on produce surfaces, which were in turn governed by produce surface properties.

Structural Considerations of Folded Protein Import through the Chloroplast TOC/TIC Translocons.

FEBS Lett 2019 Feb 18. Epub 2019 Feb 18.

Department of Plant Biology, University of California Davis, One Shields Avenue, Davis, CA, 95616.

Protein import into chloroplasts is carried out by the protein translocons at the outer and inner envelope membranes (TOC and TIC). Detailed structures for these translocons are lacking, with only a low-resolution TOC complex structure available. Recently, we showed that the TOC/TIC translocons can import folded proteins, a rather unique feat for a coupled double membrane system. Read More

J Exp Bot 2019 Feb 18. Epub 2019 Feb 18.

Genetics, Faculty of Biology, Ludwig Maximilians University Munich, Germany.

Lotus species develop infection threads to guide rhizobia into nodule cells. However, there is evidence that some species have a genetic repertoire to allow other modes of infection. Conducting confocal and electron microscopy, quantification of marker gene expression, and phenotypic analysis of transgenic roots infected with mutant rhizobia we elucidated the infection mechanism used by Rhizobium leguminosarum Norway to colonise Lotus burttii.

A microRNA biogenesis-like pathway for producing phased small interfering RNA from a long non-coding RNA in rice.

J Exp Bot 2019 Feb 18. Epub 2019 Feb 18.

Noble Research Institute, Ardmore, OK, USA.

Phased small interfering RNAs (phasiRNAs) are a class of non-coding RNAs that perform essential functions in plants. Unlike the microRNA biogenesis from a hairpin structure, the production of phasiRNAs usually requires a phase initiator and an RNA-dependent RNA polymerase (RDR) for forming double-strand RNAs. By using full-length rice cDNA (KL-cDNA) to identify phasiRNA loci, we found that a putative non-coding sequence with a long hairpin structure (LHR) generates the phasiRNAs. Read More

Medicinal Plants and Economic Development (MPED) Research Centre, Department of Botany, University of Fort Hare, Alice, 5700, South Africa.

The morbidity caused by parasite worms on susceptible hosts is of great concern and studies were carried out to explain the mechanism of infection, prevalence, host-parasite interaction and resistance of the parasite to treatment. This review elucidates the prevalence of parasitic worm infections; which is on the increases with the increase in the world population, global warming, poor standard of living particularly in troubled regions and developing nations. The neglect of the disease coupled with the resistance of these parasites to the few available drugs becomes a huge challenge that influences global disease burden. Read More

Multiple macroevolutionary routes to becoming a biodiversity hotspot.

Sci Adv 2019 Feb 6;5(2):eaau8067. Epub 2019 Feb 6.

Ecosystem and Global Change Group, Department of Plant Sciences, University of Cambridge, Downing St., Cambridge CB2 3EA, UK.

Why is species diversity so unevenly distributed across different regions on Earth? Regional differences in biodiversity may stem from differences in rates of speciation and dispersal and colonization times, but these hypotheses have rarely been tested simultaneously at a global scale. Our study reveals the macroevolutionary routes that have generated hotspots of mammal and bird biodiversity by analyzing the tempo and mode of diversification and dispersal within major biogeographic realms. Hotspots in tropical realms had higher rates of speciation, whereas those in temperate realms received more immigrant species from their surrounding regions. Read More
