Dynamics of dissolved organic matter and disinfection byproduct precursors along a low elevation gradient in woody wetlands - an implication of hydrologic impacts of climate change on source water quality.

Water Res 2020 May 11;181:115908. Epub 2020 May 11.

Baruch Institute of Coastal Ecology and Forest Science, Clemson University, Georgetown, SC, 29442, United States; Department of Environmental Engineering and Earth Science, Clemson University, South Carolina, 29634, United States.

Foliar litter is an important terrestrial source of dissolved organic matter (DOM) and disinfection byproducts (DBPs) in the source water supply. Climate changes could alter precipitation patterns and hydroperiods in woody wetlands, resulting in a hydrologic shift along the low elevation gradient and change the productions of DOC and DBP precursors and their exports to source water. Here, we conducted an 80-week field decomposition study using fresh-fallen leaves along an elevation gradient, representing well-drained, relatively moist, and inundated environments, in Congaree National Park, South Carolina.

RNAi of AGAMOUS genes in sweetgum alters reproductive organ identity and decreases fruit persistence.

Plant Direct 2020 May 21;4(5):e00225. Epub 2020 May 21.

3642 Augusta National Drive S. Salem 97302 OR USA.

Sweetgums (), members of the family Altingiaceae (Altingiales), have inflorescences and floral organs that are distinctive in structure compared with other angiosperms in which the roles of floral homeotic genes have been studied. To begin to understand the role of AGAMOUS (AG)-a floral homeotic gene that has a major role in stamen and carpel development-in development of the monosexual flowers of sweetgum, we used RNAi to reduce the expression of two members of the subfamily. Because suppression should induce floral sterility, RNAi might also provide a tool to mitigate the risks of invasiveness-and to reduce the production of its nuisance fruits or allergenic pollen-when sweetgum is used as an exotic shade or forest tree.

An Outlook on Low-Volume-Change Lithium Metal Anodes for Long-Life Batteries.

ACS Cent Sci 2020 May 1;6(5):661-671. Epub 2020 May 1.

CAS Key Laboratory of Molecular Nanostructure and Nanotechnology, CAS Research/Education Center for Excellence in Molecular Sciences, Beijing National Laboratory for Molecular Sciences (BNLMS), Institute of Chemistry, Chinese Academy of Sciences (CAS), Beijing 100190, China.

Rechargeable Li metal batteries are one of the most attractive energy storage systems due to their high energy density. However, the hostless nature of Li, the excessive dendritic growth, and the accumulation of nonactive Li induce severe volume variation of Li anodes. The volume variation can give rise to a fracture of solid electrolyte interphase, continuous consumption of Li and electrolytes, low Coulombic efficiency, fast performance degradation, and finally short cycle life.

One Health 2020 Dec 11;10:100139. Epub 2020 May 11.

The University of Sydney, c15/335 Werombi Rd, Camden, NSW 2570, Australia.

From 1976 Australia has experienced seven highly pathogenic avian influenza (HPAI) outbreaks in poultry farms and there have been a total of 16 confirmed low pathogenic avian influenza (LPAI) cases in poultry in Australia at the time of writing. This paper describes all past LPAI and HPAI detections in Australian poultry and reviews avian influenza risk in the Australian commercial chicken industry. The factors that influence this risk are also discussed; notably the nomadic nature of Australian waterfowl, the increasing demand of free range poultry egg and meat production in Australia, and biosecurity practices implemented across farms including farm separations.

Caterpillars on a phytochemical landscape: The case of alfalfa and the Melissa blue butterfly.

Ecol Evol 2020 May 21;10(10):4362-4374. Epub 2020 Apr 21.

Department of Biology Utah State University Logan UT USA.

Modern metabolomic approaches that generate more comprehensive phytochemical profiles than were previously available are providing new opportunities for understanding plant-animal interactions. Specifically, we can characterize the phytochemical landscape by asking how a larger number of individual compounds affect herbivores and how compounds covary among plants. Here we use the recent colonization of alfalfa () by the Melissa blue butterfly () to investigate the effects of indivdiual compounds and suites of covarying phytochemicals on caterpillar performance.

All-in-one sequencing: an improved library preparation method for cost-effective and high-throughput next-generation sequencing.

Plant Methods 2020 24;16:74. Epub 2020 May 24.

Shenzhen Branch, Guangdong Laboratory for Lingnan Modern Agriculture, Genome Analysis Laboratory of the Ministry of Agriculture, Agricultural Genomics Institute at Shenzhen, Chinese Academy of Agricultural Sciences, Shenzhen, 518120 China.

Background: Next generation sequencing (NGS) has been widely used in biological research, due to its rapid decrease in cost and increasing ability to generate data. However, while the sequence generation step has seen many improvements over time, the library preparation step has not, resulting in low-efficiency library preparation methods, especially for the most time-consuming and labor-intensive steps: size-selection and quantification. Consequently, there can be bottlenecks in projects with large sample cohorts. Read More
