Post-translational targeting of a recombinant protein promotes its efficient secretion into the periplasm.

Appl Environ Microbiol 2019 Apr 19. Epub 2019 Apr 19.

Division of Glycoscience, Department of Chemistry, KTH Royal Institute of Technology, AlbaNova University Centre, Stockholm, Sweden

Many recombinant proteins that are produced in have to be targeted to the periplasm to be functional. N-terminal signal peptides can be used to direct recombinant proteins to the membrane embedded Sec-translocon, a multiprotein complex that translocates proteins across the membrane into the periplasm. We have recently shown that the co-translational targeting of the single-chain variable antibody fragment BL1 saturates the capacity of the Sec-translocon leading to impaired translocation of secretory proteins and protein misfolding/aggregation in the cytoplasm.

Identification of traits associated with barley yield performance using contrasting nitrogen fertilizations and genotypes.

Plant Sci 2019 May 6;282:83-94. Epub 2018 Oct 6.

Section of Plant Physiology, University of Barcelona, Av. Diagonal 643, 08028 Barcelona, and AGROTECNIO (Centre for Research in Agrotechnology), Av. Rovira Roure 191, 25198 Lleida, Spain. Electronic address:

Much attention has been paid to understanding the traits associated with crop performance and the associated underlying physiological mechanisms, with less effort done towards combining different plant scales, levels of observation, or including hybrids of autogamous species. We aim to identify mechanisms at canopy, leaf and transcript levels contributing to crop performance under contrasting nitrogen supplies in three barley genotypes, two hybrids and one commercial line. High nitrogen fertilization did not affect photosynthetic capacity on a leaf area basis and lowered nitrogen partial factor productivity past a certain point, but increased leaf area and biomass accumulation, parameters that were closely tracked using various different high throughput remote sensing based phenotyping techniques.

High-throughput phenotyping for crop improvement in the genomics era.

Plant Sci 2019 May 12;282:60-72. Epub 2019 Jan 12.

Division of Genetics & Plant Breeding, Faculty of Agriculture (FoA), Sher-e-Kashmir University of Agricultural Sciences and Technology of Kashmir (SKUAST-K), Wadura Campus, Sopore-193201, Kashmir, India.

Tremendous progress has been made with continually expanding genomics technologies to unravel and understand crop genomes. However, the impact of genomics data on crop improvement is still far from satisfactory, in large part due to a lack of effective phenotypic data; our capacity to collect useful high quality phenotypic data lags behind the current capacity to generate high-throughput genomics data. Thus, the research bottleneck in plant sciences is shifting from genotyping to phenotyping. Read More

Quantitative and comparative analysis of whole-plant performance for functional physiological traits phenotyping: New tools to support pre-breeding and plant stress physiology studies.

Plant Sci 2019 May 17;282:49-59. Epub 2018 May 17.

The Robert H Smith Institute of Plant Sciences and Genetics in Agriculture, The Hebrew University of Jerusalem, Rehovot 7610001, Israel. Electronic address:

Plants are autotrophic organisms in which there are linear relationships between the rate at which organic biomass is accumulated and many ambient parameters such as water, nutrients, CO and solar radiation. These linear relationships are the result of good feedback regulation between a plants sensing of the environment and the optimization of its performance response. In this review, we suggest that continuous monitoring of the plant physiological profile in response to changing ambient conditions could be a useful new phenotyping tool, allowing the characterization and comparison of different levels of functional phenotypes and productivity.

Review: High-throughput phenotyping to enhance the use of crop genetic resources.

Plant Sci 2019 May 21;282:40-48. Epub 2018 Jun 21.

CSIRO Agriculture and Food, Private Mail Bag, Yanco NSW 2073 Australia.

Improved genetic, genomic and statistical technologies have increased the capacity to enrich breeding populations for key alleles underpinning adaptation and continued genetic gain. In turn, directed genomic selection together with increased heritability will reduce genetic variance to narrow the genetic base in many crop breeding programs. Diverse genetic resources (GR), including wild and weedy relatives, landraces and reconstituted synthetics, have potential to contribute novel alleles for key traits. Read More

Microbiology Unit, Department of Pure and Applied Biology, Ladoke Akintola University of Technology, Ogbomosho, Oyo State, Nigeria.

The optimization of microbial growth for biotechnological purposes traditionally requires an approach that uses only one variable at a time, which has many drawbacks. This research used a completely randomized approach to optimize carbon and nitrogen nutrient requirements and growth factors (pH and temperature) for Pleurotus tuber-regium in order to optimally produce biomass and extracellular polysaccharide (EPS) in shake-flask cultures. An artificial neural network (ANN) module was used to simulate the fungus-growing process and hence determine optimal conditions. Read More

Resolving the Measurement Uncertainty Paradox in Ecological Management.

Am Nat 2019 May 5;193(5):645-660. Epub 2019 Apr 5.

Ecological management and decision-making typically focus on uncertainty about the future, but surprisingly little is known about how to account for uncertainty of the present: that is, the realities of having only partial or imperfect measurements. Our primary paradigms for handling decisions under uncertainty-the precautionary principle and optimal control-have so far given contradictory results. This paradox is best illustrated in the example of fisheries management, where many ideas that guide thinking about ecological decision-making were first developed. Read More

Temperature and phosphorus interacts in controlling the picoplankton carbon flux in the Adriatic Sea: an experimental vs. field study.

Environ Microbiol 2019 Apr 19. Epub 2019 Apr 19.

Institute of Oceanography and Fisheries, Split, Croatia.

Temperature and phosphorus positively interacted in controlling picoplankton biomass production and its transfer towards higher trophic levels. Two complementary approaches (experimental and field study) indicated several coherent patterns: (1) the impact of temperature on heterotrophic bacteria was high at temperatures lower than 16 C and levelled off at higher temperatures, whereas this impact on autotrophic picoplankton was linear along the entire range of the investigated temperatures; (2) the addition of phosphorus increased the values of picoplankton production and grazing, but did not change the nature of their relationships with temperature substantially; (3) the picoplankton carbon flux towards higher trophic levels was larger during the warmer months (grazing by HNF dominated during the warmer period and by ciliates during the colder period) and also strengthened in conditions without phosphorus limitation; (4) the hypothesis that the available phosphorus can be better utilized at higher temperatures was confirmed for both autotrophic and heterotrophic picoplankton; (5) the hypothesis that the rise in temperature stimulates growth only in conditions of sufficient phosphorus was confirmed only for heterotrophic bacteria. Therefore, in the global warming scenario, an increase of the picoplankton carbon flux towards higher trophic levels can be expected in the Adriatic Sea, particularly under unlimited phosphorus conditions.

Precipitation and temperature drive continental-scale patterns in stream invertebrate production.

Sci Adv 2019 Apr 17;5(4):eaav2348. Epub 2019 Apr 17.

Department of Life Sciences, Imperial College London, Silwood Park Campus, Buckhurst Rd., Ascot, Berkshire SL5 7PY, UK.

Secondary production, the growth of new heterotrophic biomass, is a key process in aquatic and terrestrial ecosystems that has been carefully measured in many flowing water ecosystems. We combine structural equation modeling with the first worldwide dataset on annual secondary production of stream invertebrate communities to reveal core pathways linking air temperature and precipitation to secondary production. In the United States, where the most extensive set of secondary production estimates and covariate data were available, we show that precipitation-mediated, low-stream flow events have a strong negative effect on secondary production.

Fungi Originating From Tree Leaves Contribute to Fungal Diversity of Litter in Streams.

Front Microbiol 2019 2;10:651. Epub 2019 Apr 2.

Ecology and Genetics, University of Oulu, Oulu, Finland.

Biomass production and decomposition are key processes in ecology, where plants are primarily responsible for production and microbes act in decomposition. Trees harbor foliar microfungi living on and inside leaf tissues, epiphytes, and endophytes, respectively. Early researchers hypothesized that all fungal endophytes are parasites or latent saprophytes, which slowly colonize the leaf tissues for decomposition. Read More

Food Res Int 2019 Jun 31;120:441-448. Epub 2018 Oct 31.

Embrapa Agroindústria de Alimentos, Rio de Janeiro, Brazil. Electronic address:

A cocktail of biomass hydrolytic enzymes was produced by solid-state fermentation (SSF) by the mutant strain Aspergillus niger 3T5B8, using as substrate a mixture of grape pomace and wheat bran, and compared to the production when wheat bran was used as the sole substrate. The two enzymatic cocktails were subsequently used for the extraction of bioactive compounds from grape pomace and the relationship between the activities of the cocktail and the release of phenolic compounds was evaluated. Although the wheat bran SSF process was more effective for enzyme production, the enzymatic cocktail produced by the grape pomace - wheat bran mixture was more effective for the extraction of compounds with higher proanthocyanidins content and higher antioxidant potential (p < 0.
