Deep-learning-based removal of autofluorescence and fluorescence quantification in plant-colonizing bacteria in vivo.

New Phytol 2022 Jun 26. Epub 2022 Jun 26.

University of Bremen, Faculty of Biology and Chemistry, CBIB Center for Biomolecular Interactions, Department of Microbe-Plant Interactions, P.O. Box 33 04 40, D-28334, Bremen, Germany.

Fluorescence microscopy is common in bacteria-plant interaction studies. However, strong autofluorescence from plant tissues impedes in vivo studies on endophytes tagged with fluorescent proteins. To solve this problem, we developed a deep-learning-based approach to eliminate plant autofluorescence from fluorescence microscopy images, tested for the model endophyte Azoarcus olearius BH72 colonizing Oryza sativa roots.

Natural variation in the transcription factor Replumless contributes to both disease resistance and plant growth in Arabidopsis.

Plant Commun 2022 Jun 24:100351. Epub 2022 Jun 24.

School of Life Sciences and School of Advanced Agricultural Sciences, State Key Laboratory of Protein and Plant Gene Research, Peking-Tsinghua Center for Life Sciences, Peking University, Beijing 100871, China. Electronic address:

When attacked by pathogens, plants need to reallocate energy from growth to defense to fend off the invaders, which frequently incurs growth penalties. This phenomenon is known as growth-defense tradeoff, which is orchestrated by a hardwired transcriptional network. Altering key factors involved in this network has the potential to increase disease resistance without growth or yield loss, but the mechanisms underlying such changes need further investigation.

Semiochemical oviposition cues to control Aedes aegypti gravid females: state of the art and proposed framework for their validation.

Parasit Vectors 2022 Jun 25;15(1):228. Epub 2022 Jun 25.

Laboratory of Vector Control Research, Institute Pasteur of Guadeloupe, Lieu-dit Morne Jolivière, 97139, Les Abymes, Guadeloupe, France.

In the fight against mosquito-borne diseases, odour-based lures targeting gravid females represent a promising alternative to conventional tools for both reducing mosquito populations and monitoring pathogen transmission. To be sustainable and effective, they are expected to use semiochemicals that act specifically against the targeted vector species. In control programmes directed against Aedes aegypti, several candidates of different origins (conspecifics, plants) have already been identified as potential oviposition attractants or repellents in laboratory experiments.

Microplate bioassay to examine the effects of grapevine-isolated stilbenoids on survival of root knot nematodes.

BMC Res Notes 2022 Jun 25;15(1):220. Epub 2022 Jun 25.

Crop Diseases, Pests and Genetics Research Unit, USDA-ARS San Joaquin Valley Agricultural Sciences Center, 9611 S. Riverbend Ave, Parlier, CA, 93648, USA.

Objectives: Root knot nematodes can be major pests in vineyards and cause significant yield losses over time. Control involves the use of different resistant grapevine rootstocks, but it remains unclear the mechanisms that such rootstocks possess to limit root knot nematode infections. Defense-associated compounds called stilbenoids, a type of phenolic compound, are present in relatively substantial amounts in grapevine root tissues. Read More

specificity: an R package for analysis of feature specificity to environmental and higher dimensional variables, applied to microbiome species data.

Environ Microbiome 2022 Jun 25;17(1):34. Epub 2022 Jun 25.

Division of Biomedical Informatics and Personalized Medicine, University of Colorado School of Medicine, Aurora, CO, USA.

Background: Understanding the factors that influence microbes' environmental distributions is important for determining drivers of microbial community composition. These include environmental variables like temperature and pH, and higher-dimensional variables like geographic distance and host species phylogeny. In microbial ecology, "specificity" is often described in the context of symbiotic or host parasitic interactions, but specificity can be more broadly used to describe the extent to which a species occupies a narrower range of an environmental variable than expected by chance.

Accurate recombination estimation from pooled genotyping and sequencing: a case study on barley.

BMC Genomics 2022 Jun 25;23(1):468. Epub 2022 Jun 25.

Institute of Quantitative Genetics and Genomics of Plants, Heinrich Heine University, 40225, Düsseldorf, Germany.

Sexual reproduction involves meiotic recombination and the creation of crossing over between homologous chromosomes, which leads to new allele combinations. We present a new approach that uses the allele frequency differences and the physical distance of neighboring polymorphisms to estimate the recombination rate from pool genotyping or sequencing. This allows a considerable cost reduction compared to conventional mapping based on genotyping or sequencing data of single individuals. Read More

FANCM promotes class I interfering crossovers and suppresses class II non-interfering crossovers in wheat meiosis.

Nat Commun 2022 Jun 25;13(1):3644. Epub 2022 Jun 25.

Department of Genetics and Genome Biology, Adrian Building, University of Leicester, University Road, Leicester, LE1 7RH, UK.

FANCM suppresses crossovers in plants by unwinding recombination intermediates. In wheat, crossovers are skewed toward the chromosome ends, thus limiting generation of novel allelic combinations. Here, we observe that FANCM maintains the obligate crossover in tetraploid and hexaploid wheat, thus ensuring that every chromosome pair exhibits at least one crossover, by localizing class I crossover protein HEI10 at pachytene.

Narrowing down molecular targets for improving phosphorus-use efficiency in maize (Zea mays L.).

Mol Biol Rep 2022 Jun 25. Epub 2022 Jun 25.

ICAR - Indian Institute of Maize Research, PAU Campus, Ludhiana, 141004, India.

Conventional agricultural practices rely heavily on chemical fertilizers to boost production. Among the fertilizers, phosphatic fertilizers are copiously used to ameliorate low-phosphate availability in the soil. However, phosphorus-use efficiency (PUE) for major cereals, including maize, is less than 30%; resulting in more than half of the applied phosphate being lost to the environment. Read More

Molecular characterization of a novel virga-like virus associated with wheat.

Arch Virol 2022 Jun 25. Epub 2022 Jun 25.

State Key Laboratory for Managing Biotic and Chemical Threats to the Quality and Safety of Agroproducts, Key Laboratory of Biotechnology in Plant Protection of MOA of China and Institute of Plant Virology, Ningbo University, Ningbo, 315211, China.

In this work, we report the detection of a novel single-strand RNA virus from wheat, tentatively named "Triticum aestivum-associated virga-like virus 1" (TaAVLV1). Further characterization revealed that the complete genome of TaAVLV1 is divided into two segments, RNA1 and RNA2, which are 3530 and 3466 nt in length, excluding their respective polyA tails, and each contains only one open reading frame (ORF). The ORF of RNA1 encodes an RNA-dependent RNA polymerase (RdRp), while the ORF of RNA2 encodes a putative protein with methyltransferase and helicase domains. Read More

Multi-omics reveals mechanisms of resistance to potato root infection by Spongospora subterranea.

Sci Rep 2022 Jun 25;12(1):10804. Epub 2022 Jun 25.

Tasmanian Institute of Agriculture, New Town Research Laboratories, University of Tasmania, 13 St Johns Avenue, New Town, TAS, 7008, Australia.

The pathogen Spongospora subterranea infects potato roots and developing tubers resulting in tuber yield and quality losses. Currently, there are no fully effective treatments for disease control. Host resistance is an important tool in disease management and understanding the molecular mechanisms of defence responses in roots of potato plants is required for the breeding of novel resistant cultivars.

Global PBDE contamination in cetaceans. A critical review.

Environ Pollut 2022 Jun 22:119670. Epub 2022 Jun 22.

Department of Instrumental Analysis and Environmental Chemistry, Institute of Organic Chemistry (IQOG-CSIC), Juan de la Cierva 3, 28006, Madrid, Spain.

This review summarizes the most relevant information on PBDEs' occurrence and their impacts in cetaceans at global scale, with special attention on the species with the highest reported levels and therefore the most potentially impacted by the current and continuous release of these substances. This review also emphasizes the anthropogenic and environmental factors that could increase concentrations and associated risks for these species in the next future. High PBDE concentrations above the toxicity threshold and stationary trends have been related to continuous import of PBDE-containing products in cetaceans of Brazil and Australia, where PBDEs have never been produced.
