Occurrence of Causing Fusarium Wilt on Carthusian Pink in China.

Carthusian pink (Dianthus carthusianorum) is native to Europe and is widely grown in China for landscaping. In September 2022, wilting symptoms of carthusian pink were found in Xixia City (33°18'31″ N, 111°29'45″ E), Henan Province, China, with a disease incidence of 65%. Approximately 100 plants were surveyed on the landscaping lawns of the park.

Leaf Spot Disease on Caused by in China.

Pomegranate (Punica granatum L.), which is native to central Asia, is considered as one of the most renowned commercial fruit trees in the world. The planting area in China is roughly 120 thousand hectares.

Gray Blight Disease on Caused by in China.

Euonymus japonicas is widely planted as an important landscape species throughout China. In June 2021, a serious gray blight disease was detected on E. japonicas in Henan Province (32°30'58" N, 112°19'44" E), causing severe defoliation of infected trees with a foliar disease incidence of 52 to 70% (n = 100).

[High-Throughput Sequencing Combined with Metabonomics to Analyze the Effect of Heavy Metal Contamination on Farmland Soil Microbial Community and Function].

Heavy metal contamination affects microbial composition and diversity. The interaction between heavy metal contamination and soil microorganisms has been a hot topic in ecological research. Battery manufacturing has been going on for over six decades in Xinxiang City, resulting in severe soil heavy metal contamination due to battery wastewater runoff.

Characterization of a novel chitinolytic Serratia marcescens strain TC-1 with broad insecticidal spectrum.

The Gram-negative rod-shaped bacterium Serratia marcescens is an opportunistic pathogen of many organisms, including insects. We report the identification and optimal in vitro chitinase production conditions of a novel chitinolytic S. marcescens strain TC-1 isolated from a naturally infected white grub (Anomala corpulenta) collected from a peanut field at Nanyang city, Henan province, China.

Plant organ- and growth stage-diversity of endophytic bacteria with potential as biofertilisers isolated from wheat (Triticum aestivum L.).

Background: Chemical fertilisers are extensively used for crop production, which may cause soil deterioration and water pollution. Endophytic bacteria with plant-growth-promoting (PGP) activities may provide a solution to sustainably improve crop yields, including in-demand staples such as wheat. However, the diversity of the PGP endophytic bacteria in wheat across plant organs and growth stages has not been thoroughly characterised.

[Polyamine-producing Bacteria Regulated the Community Structure of Rhizosphere Bacteria and Reduced the Absorption of Cd in Wheat].

Some functional microorganisms in the soil immobilize heavy metals by adsorption and precipitation, prevent the absorption of heavy metals by crops, and play an important role in the passivation and remediation of medium and mild heavy metal-contaminated soil. A pot experiment was conducted to study the effects of the exogenous polyamine-producing bacterium sp. N3 on Cd uptake and the bacterial community composition and function in the rhizosphere soil.

sp. nov., a novel phenylacetic acid degrading bacterium isolated from sludge.

A novel bacterium, designated BD-1, was isolated from a sludge sample. Cells of the novel Gram-stain-negative strain were identified to be facultative anaerobic, non-motile and short rod-shaped. Growth occurred at 15-37 °C (optimum, 30 °C), pH 5.

[Functional Stability and Applicability of Heavy Metal Passivators in Reducing Cd Uptake by Lettuce].

The use of heavy metal passivators to prevent vegetables from absorbing heavy metals is an important measure to control heavy metal-polluted vegetable fields and to ensure the safe production of vegetables. A pot experiment of planting three times in succession was conducted to study the effects of N3 (N3), rice husk biochar (BC), sheep manure organic fertilizer (SM), strain N3 combined with biochar (BC+N3), and strain N3 combined with sheep manure (SM+N3) on Cd uptake and the functional stability of lettuce using a heavy metal passivator only at the first planting. The comprehensive applicability of the passivation materials was evaluated by the dynamic weighted comprehensive function.

First Report of Soft Rot Caused by Aspergillus niger sensu lato on Mother-in-law's Tongue in China.

"Mother-in-law's tongue" (MLT) [Dracaena trifasciata (Prain) Mabb. (syn. Sansevieria trifasciata Prain.

[Community Structure and Predictive Functional Analysis of Surface Water Bacterioplankton in the Danjiangkou Reservoir].

Bacterioplankton are important components of aquatic ecosystems, and play a crucial role in the global biogeochemical cycle of nitrogen. In this study, surface-water samples were collected from Kuxin (the center of Danjiangkou Reservoir) and Qushou (the Middle Route of the South-to-North Water Diversion Project's canal head) in the Danjiangkou Reservoir in May 2016. Total DNA was isolated, and high-throughput sequencing was performed to analyze the community structure and diversity of bacteria.

[Composition and Predictive Functional Analysis of Rhizosphere Bacterial Communities in Riparian Buffer Strips in the Danjiangkou Reservoir, China].

Microbial communities play crucial roles in the global biogeochemical nitrogen cycle. To our knowledge, the compositions and functions of rhizosphere communities in riparian buffer strips have not been reported. In this study, rhizosphere soil samples were collected from herbs ( and ), trees (), and shrubs () in the Danjiangkou Reservoir in June 2017.

Biocontrol Agents for Controlling Wheat Rust.

Bacterial endophytes are potential biocontrol agents of wheat rusts. Apart from disease control, these bacterial endophytes have growth-promoting efficacies which differ significantly from one isolate to another. Here, we describe the procedure for isolation, screening, and identification of endophytic bacterial isolates with high capacities to suppress strip rust infection and better ability to enhance wheat yields.
