Detection and Quantification of Apple Stem Grooving Virus in Micropropagated Apple Plantlets Using Reverse-Transcription Droplet Digital PCR.

Plant Pathol J 2022 Aug 1;38(4):417-422. Epub 2022 Aug 1.

Department of Applied Biology, Institute of Environmentally Friendly Agriculture, Chonnam National University, Gwangju 61185, Korea.

Apple stem grooving virus (ASGV) is a destructive viral pathogen of pome fruit trees that causes significant losses to fruit production worldwide. Obtaining ASGV-free propagation materials is essential to reduce economic losses, and accurate and sensitive detection methods to screen ASGV-free plantlets during in vitro propagation are urgently necessary. In this study, ASGV was sensitively and accurately quantified from in vitro propagated apple plantlets using a reverse transcription droplet digital polymerase chain reaction (RT-ddPCR) assay.

Effectiveness assessment of reservoir projects for flash flood control, water supply and irrigation in Wangmo Basin, China.

Sci Total Environ 2022 Aug 7:157918. Epub 2022 Aug 7.

Changjiang River Scientific Research Institute of Changjiang River ResourcesCommission,Wuhan 430010, China.

Most flash floods in countries around the world occur in poor rural mountainous areas and typically cause more casualties and economic losses due to monitoring challenges and early warning difficulties. In mountainous regions, reservoir projects are a very effective measure for mitigating the risk of flash floods and can also be used for water supplies and irrigation, but there is a lack of research on the comprehensive benefit assessments of reservoirs. In this paper, we simulate the inundation extents of flash floods for the Wangmo Basin in China, where flash floods frequently occur, under different return periods using the HEC-HMS (HEC-Hydrologic Modelling System) model and FLO-2D model and compare the resulting housing losses with and without reservoirs.

Carbon Dots Improve Nitrogen Bioavailability to Promote the Growth and Nutritional Quality of Soybeans under Drought Stress.

ACS Nano 2022 Aug 10. Epub 2022 Aug 10.

Stockbridge School of Agriculture, University of Massachusetts, Amherst, Massachusetts 01003, United States.

The inefficient utilization of nitrogen (N) in soil and drought stress seriously threatens agricultural and food production. Herein, soil application of carbon dots (CDs, 5 mg kg) promoted the growth and nutritional quality of soybeans by improving N bioavailability, which was beneficial to alleviate the economic losses caused by drought stress. Soil application of CDs enhanced the N-fixing ability of nodules, regulated rhizosphere processes, and ultimately enhanced N and water uptake in soybeans under drought stress. Read More

Research progress in toxicological effects and mechanism of aflatoxin B toxin.

PeerJ 2022 4;10:e13850. Epub 2022 Aug 4.

College of Animal Science and Technology, Henan University of Animal Husbandry and Economy, Zhengzhou, Henan, China.

Fungal contamination of animal feed can severely affect the health of farm animals, and result in considerable economic losses. Certain filamentous fungi or molds produce toxic secondary metabolites known as mycotoxins, of which aflatoxins (AFTs) are considered the most critical dietary risk factor for both humans and animals. AFTs are ubiquitous in the environment, soil, and food crops, and aflatoxin B(AFB) has been identified by the World Health Organization (WHO) as one of the most potent natural group 1A carcinogen.

Crown dieback and mortality of urban trees linked to heatwaves during extreme drought.

Sci Total Environ 2022 Aug 6:157915. Epub 2022 Aug 6.

Hawkesbury Institute for the Environment, Western Sydney University, Penrith, NSW 2751, Australia.

Cities have been described as 'heat islands' and 'dry islands' due to hotter, drier air in urban areas, relative to the surrounding landscape. As climate change intensifies, the health of urban trees will be increasingly impacted. Here, we posed the question: Is it possible to predict urban tree species mortality using (1) species climate envelopes and (2) plant functional traits? To answer these, we tracked patterns of crown dieback and recovery for 23 common urban tree and shrub species in Sydney, Australia during the record-breaking austral 2019-2020 summer. Read More

Environ Res 2022 Aug 6:114015. Epub 2022 Aug 6.

College of Resources and Environmental Sciences, National Academy of Agriculture Green Development, Key Laboratory of Plant-Soil Interactions, Ministry of Education, China Agricultural University, 100193, Beijing, China. Electronic address:

Excessive application of chemical nitrogen (N) fertilizer and inefficient N management are still common in the North China Plain, leading to large reactive N (Nr) losses and pollution, threatening environmental security and public health. Three improved N management practices (33% reduction in N applied (OU), OU combined with partial organic fertilizer substitution (UOM) and the urea in UOM amended with a urease inhibitor (ULOM)) together with no N application (CK) and farmers' conventional practice (CU) were tested on a maize-wheat rotation at Quzhou, Hebei, North China Plain (NCP). Nr emissions were related to WFPS (Water Filled Pore Space), soil mineral N (NH-N and NO-N) and soil temperature. Read More

Should and will "cultured meat" become a reality in our plates?

Adv Food Nutr Res 2022 25;101:181-212. Epub 2022 May 25.

INRAE, University of Clermont-Ferrand, VetAgro Sup, Saint Genès Champanelle, France.

Produced from proliferating cells in bioreactors with a controlled culture medium, "cultured meat" has been presented by its supporters, who are mainly private actors (start-ups), as a sustainable solution to meet the growing demand for animal proteins without weaknesses of animal husbandry in terms of environmental impact, animal welfare or even health. The aim of this chapter is to take stock of current knowledge on the potential benefits and pitfalls of this novel product. Since robust scientific arguments are lacking on these aspects, there is no consensus on the health and nutritional qualities of "cultured meat" for human consumption and on its potential low environmental impact.

Efficacy of Acidified Oils against in Low-Moisture Environments.

Appl Environ Microbiol 2022 Aug 8:e0093522. Epub 2022 Aug 8.

Department of Food Science, University of Massachusetts, Amherst, Massachusetts, USA.

When processing low-moisture, high-fat foods such as peanut butter and nuts, water-based sanitization is unsuitable due to the immiscible nature of water and fats. Dry sanitization mainly uses flammable compounds such as isopropanol, requiring equipment cooling before application. The use of oils to deliver antimicrobials against foodborne pathogens enables the use of elevated temperatures, thus eliminating processing downtimes associated with dry sanitization. Read More

Gross, histopathologic, microbiologic, and radiologic characterization of lesions associated with clinical lameness in a cohort of group-housed sows euthanized for lameness.

Vet Pathol 2022 Aug 8:3009858221114470. Epub 2022 Aug 8.

University of Pennsylvania, Kennett Square, PA.

Lameness in sows is reported as the most frequent cause of early culling from commercial farms and results in reduced productivity, economic losses, and a negative impact on animal welfare. Osteochondrosis was reported as the leading cause of lameness in North American sows and, although more recent European studies report infectious arthritis as the leading cause, lameness in US production facilities using group housing for gestating sows has not yet been evaluated. This study's aim was to characterize lesions associated with lameness in the appendicular musculoskeletal system of 26 sows euthanized for lameness using pathologic, radiologic, and microbiologic analyses.
