Heavy metal pollution of paddy fields is increasing concern due to the huge losses in rice yield that occur every year. Therefore, it important understand microecological and physicochemical changes soil under varying cadmium (Cd) levels. Here, we explore bacterial community response contamination agricultural soil. Our results reveal high level sites displayed lower diversity indices than low groups. In addition, total available exhibited significant negative correlations with indices. The...

The phyllosphere is colonized by a wide variety of microorganisms including epiphytes, plant-pathogenic fungus, bacteria, as well human or animal pathogens. However, little known about how microbial community composition changes with the development angular leaf-spot cucumber. Here, 18 mixed samples were collected based on lesion coverage rate (LCR) cucumber from three disease severity groups (DM1: symptomatic-mild, DM2: symptomatic-moderate, DM3: symptomatic-severe). In our study, structure...

Phyllosphere microbiota play a crucial role in plant-environment interactions and their microbial community function are influenced by biotic abiotic factors. However, there is little research on how pathogens affect the of phyllosphere fungi. In this study, we collected 16 pumpkin (

Abstract Background Soybean-corn intercropping is widely practised by farmers in Southwest China. Although rhizosphere microorganisms are important nutrient cycling processes, the differences microbial communities between intercropped soybean and corn their monoculture poorly known. Additionally, effects of cadmium (Cd) pollution on these have not been examined. Therefore, a field experiment was conducted Cd-polluted soil to determine monocultures soybean–corn systems Cd concentrations...

Antibiotics are widely added to swine forage and the main reason for environmental accumulation of antibiotic resistance genes (ARGs) in manure-dwelling microorganisms. Aerobic composting (AC) anaerobic digestion (AD) efficient methods converting manure bio-fertilizer while degrading residual antibiotics. However, influence these on ARG difference their efficiency have rarely been investigated. In this study, we explored variations four tetracycline antibiotics (TCs) associated ARGs...

Abstract Purpose The application of fungicides is one the main strategies to prevent clubroot disease. Currently, numerous studies focus on changes in soil microbial community at different levels disease severity. However, effects and causative pathogen, Plasmodiophora brassicae , while preventing remain unclear. Methods In this study, we evaluated control efficacy three (fluazinam, metalaxyl-mancozeb, carbendazim) tumorous stem mustard greenhouse experiment. Uninoculated Water treatments...

In recent years, the photosynthetic bacteria have been used widely in agriculture, but effects of different agricultural applications on crop rhizosphere microorganism and crops are lack. this study, we provide new insights into structure composition rice root-associated microbiomes as well effect Rhodopseudomonas palustris(R. palustris) PSB06 CGA009 at seedling stage with seed immersion root irrigation. Compare CK group, length stem, peroxidase (POD), superoxide dismutase (SOD) activities...

A novel actinobacterial strain, designated SDT, was isolated from rhizosphere soil of Chinese cabbage in Shandong province, China. The cells were aerobic, Gram-staining-positive, oxidase- and catalase-positive, short rods formed white colonies on trypticase soy agar. cell-wall peptidoglycan contained meso-diaminopimelic acid as the diagnostic diamino alanine, glutamic leucine. Diphosphatidylglycerol predominant polar lipid. cellular fatty C18 : 1ω9c; minor components anteiso-C15 0...

The Rhodopseudomonas palustris ( R. ) PSB06 can promote crop growth, as it maybe regulates microbial communities in plant root soil, soil physicochemical properties, thus creating a favorable habitat for the growth. However, there are few studies on yields and rhizosphere community of agent. In study, high-throughput sequencing was used to study changes bacterial after treatment. results indicated agent increased pepper yield by 33.45% when compared control group, with better effect than...

Abstract Begomoviruses can modify their transmission vector, Bemisia tabaci , to benefit spread, although this may not always be the case. Here, new begomovirus Ramie mosaic virus (RaMoV) and its vector B. MED, which is dominant in China many regions of world, were used as a model examine direct indirect interaction by MED different sexes. No significant or effects RaMoV observed females, could shorten life span females up 4 days. A test sexes showed that there was higher efficiency than...

The variation of phyllosphere bacterial and fungal communities along elevation gradients may provide a potential link with temperature, which corresponds to an over short geographic distances. At the same time, plant growth stage is also important factor affecting microorganisms. Understanding microbiological diversity changes in among stages for developing crop ecological theories. Thus, we investigated variations composition rice at five sites gradient from 580 980 m above sea level (asl)...

In China, citrus Huanglongbing (HLB) disease is caused by the Candidatus Liberibacter asiaticus bacterium, which carried Asian psyllid Diaphorina citri Kuwayama. It was hypothesized that epidemic of HLB may related with rate bacterium presence in insect vector and content plant tissues, as well phyllosphere microbe communities changes. This study systematically analyzed or absence Ca. L. tree leaves D. over a 6-year period using real-time PCR. addition, changes number bacteria 12 months were...

The use of biological pesticide can greatly reduce the soil pollution in environment. Exploring effect on community diversity and distribution pathogenic bacteria will provide theoretic basis for subsequent researches micro-ecological control. In order to explore microbial ecological mechanism pepper phytophthora blight, this research compared difference between rhizosphere infected healthy plants, effects Rhodopseudomonas palustris PSB06 diversities plant were investigated using Illumina...

Phyllosphere microbiota play a crucial role in plant-environment interactions and are influenced by biotic abiotic factors. However, there is little research on how pathogen s affect the microbial community. In this study, we collected 16 pumpkin ( Cucurbita moschata ) leaf samples showing symptoms of powdery mildew disease with different severity levels ranging from L1 (least severe) to L4 (most severe). We examined fungal community structure diversity Illumina MiSeq sequencing internal...
