Long-term nitrogen addition facilitates phosphorus uptake by the roots of .

We conducted a field nitrogen addition experiment in a subtropical natural forest taking ammonium nitrate as nitrogen source. There were three nitrogen addition levels: 0, 20, and 80 kg N·hm·a, corresponding to the control, low nitrogen, and high nitrogen treatments, respectively. In the ninth year of treatments, we collected samples of surface soil from 0 to 15 cm to determine soil basic chemical properties, microbial community composition, acid phosphatase activity, and analyzed leaf nitrogen and phosphorus contents, leaf phosphorus fractions, and fine root biomass and phosphorus content in .

RNA Interference-Aided Functional Characterization of Juvenile Hormone Signaling During Vitellogenesis in Two Coleoptera Species.

In Tribolium castaneum, juvenile hormone (JH) signal, through Methoprene-tolerant (Met)/Taiman (Tai) heterodimer, regulates vitellogenesis. Considering that Coleoptera is by far the largest animal taxon, whether JH pathway controls vitellogenesis remains to be clarified in other Coleopteran species. In the current paper, temporal expression determination revealed that JH signal is triggered in the young female adults in two Henosepilachna species, consistent with active oogenesis and vitellogenesis in these beetles.

Change of soil dissolved organic matter and its association with fungal communities after short-term nitrogen addition in different tree species.

Soil dissolved organic matter (DOM) is an important component of soil carbon pool, and its interaction with soil fungal communities is crucial for soil carbon cycle. We set up three nitrogen (N) addition levels, including control (0 kg N·hm·a), low N (40 kg N·hm·a), and high N (80 kg N·hm·a), in and forests to explore the effect of N addition on the DOM quantity and optical properties, as well as the relationship between soil fungal communities and DOM by using three-dimensional fluorescence spectroscopy coupled with parallel factor analysis and high-throughput sequencing. The results showed that N addition did not significantly change the quantity or optical properties of soil DOM and Chao1 index in forest.

[Short-term nitrogen addition reduces soil microbial nitrogen fixation rate in subtropical and forests].

Biological nitrogen (N) fixation is an important source of N in terrestrial ecosystems, but the response of soil microbial N fixation rate to N deposition in different forest ecosystems still remains uncertain. We conducted a field N addition experiment to simulate atmosphere N deposition in subtropical and forests. We set up three levels of nitrogen addition using urea as the N source: 0 (control), 40 (low N), and 80 g N·hm·a(high N) to examine the chemical properties, microbial biomass C, enzyme activities, and gene copies of top soils (0-10 cm).

RNA Interference-Mediated Suppression of Ecdysone Signaling Inhibits Choriogenesis in Two Coleoptera Species.

During choriogenesis in insects, chorion (eggshell) is formed by surrounding follicular epithelial cells in ovarioles. However, the regulatory endocrine factor(s) activating choriogenesis and the effect of chemical components on eggshell deserve further exploration. In two representative coleopterans, a coccinellid and a chrysomelid , genes encoding the 20-hydroxyecdysone (20E) receptor heterodimer, ecdysone receptor (EcR) and ultraspiracle (USP), and two chitin biosynthesis enzymes UDP-N-acetylglucosamine pyrophosphorylase (UAP) and chitin synthase (ChS1), were highly expressed in ovaries of the young females.

A Universal Aptamer for Influenza A Viruses: Selection, Recognition, and Infection Inhibition.

It is crucial to develop universal inhibitors for viral inhibition due to the rapid mutation of viruses. Herein, a universal aptamer inhibitor was developed that enabled a single DNA molecule to recognize several hemeagglutinin (HA) protein subtypes, inducing broad neutralization against influenza A viruses (IAVs). Through a multi-channel enrichment (MCE) strategy, a high-affinity aptamer named UHA-2 was obtained, with its dissociation constants () for three different HA proteins being 1.

[Research Progress on Colloid Pump Effect of Micro- and Nanoplastics in Drinking Water].

Currently, micro- and nanoplastics are the most concerning pollutants, which have been confirmed to exist in every stage of drinking water treatment process. Micro- and nanoplastics in drinking water have large specific surface areas, which could adsorb inorganic matter, organic matter, and microorganisms, thereby increasing their risk to human health. The adsorption and agglomeration behavior of micro- and nanoplastics on typical pollutants is called the "colloid pump effect.

Requirement of Snakeskin for normal functions of midgut and Malpighian tubules in Henosepilachna vigintioctopunctata.

Septate junctions (SJs) are located between epithelial cells and play crucial roles in epithelial barrier formation and epithelia cell homeostasis. Nevertheless, the molecular constituents, especially those related to smooth SJs (sSJs), have not been well explored in non-Drosophilid insects. A putative integral membrane protein Snakeskin (Ssk) was identified in a Coleoptera foliar pest Henosepilachna vigintioctopunctata.

Overexpression of EphB6 and EphrinB2 controls soma spacing of cortical neurons in a mutual inhibitory way.

To establish functional circuitry, neurons settle down in a particular spatial domain by spacing their cell bodies, which requires proper positioning of the soma and establishing of a zone with unique connections. Deficits in this process are implicated in neurodevelopmental diseases. In this study, we examined the function of EphB6 in the development of cerebral cortex.
