Abstract Biofilter is the core unit of recirculating aquaculture system(RAS), which mainly to achieve in situ purification and restoration water pollutants by enriching microorganisms on biofilters form biofilms. To explore changes metabolic characteristics microbial communities process biofilm formation RAS under low-temperature environment, 16S rRNA high-throughput sequencing was applied anal...

ABSTRACT The common bean, a legume of significant economic importance, is renowned for its extensive genetic variability. It crucial to comprehend diversity, analyze population structure, and understand relationships among commercial classes accessions facilitate improvement. This study aimed molecularly characterize 143 bean by employing 25 SSR molecular markers. objectives were estimate clust...

Abstract The discharge of acid mine drainage from abandoned high sulfur (S) coal mines has caused serious pollution in the Shandi River, Yangquan, Shanxi Province. To determine impact long-term on microorganisms river, we collected river sediments a polluted tributary (Group P) and mainstream River R) to study bacterial diversity community composition. results showed that was seriously by mines...

Most orthopteran insects are phytophagous and some important pests in agriculture forests. Many intestinal microflora of Orthoptera have been reported, primarily from Acridoidea there few reports other taxa. In this study, we collected 15 individuals representing five species ( Ruspolia lineosa , Tetrix japonica Erianthus versicolor Gryllotalpa orientalis Teleogryllus emma ) belonging to superf...

In order to study the linkages between crop straw decomposition rate and change in soil biological properties after returned with different iron (Fe2+) contents, a 180-day incubation experiment was performed examine of maize (MS) under three Fe2+ levels, i.e., 0, 0.3, 1 mg g−1. Enzyme activities regarding microbial communities 0 g−1 Fe addition were also detected. The results showed that signif...

The microbiota in raw milk plays an important role the health of dairy cows and safety products, which might be influenced by that teat skin. However, composition skin, as well bacterial interaction between two adjacent spatial locations, remains elusive. Here, we investigated composition, diversity, co-occurrence network communities on shift during bath using 469 samples from 156 individual co...

This study aimed to analyze the genetic variability and estimate diversity parameters of 23 elite papaya lines based on microsatellite molecular markers. The plant material was composed lines, 18 from 'Formosa' five 'Solo' group. expected heterozygosity (HE), observed (HO), coefficient inbreeding (ƒ) for each genotype were estimated. weighted index obtained dissimilarity matrix, estimated dista...

Petrocoptis montsicciana and P. pardoi are two Iberian endemic taxa of Caryophyllaceae family with an unclear taxonomic delimitation, being variously treated as independent species, subspecies or even synonyms. In the present study, allozyme raw data obtained in early 2000s have been reused improved tools to survey genetic structure, complemented modeling niche comparative analyses shed light o...

Knowledge about the population genetic variation of the endangered orchid, Cypripedium japonicum, is conducive to the development of conservation strategies. Here, we examined the levels and partitioning of inter-simple sequence repeat (ISSR) diversity (109 loci) in five populations of this orchid to gain insight into its genetic variation and population structure in Eastern and Central China. ...

Siberian wild rye (Elymus sibiricus L.) is an important native grass in the Qinghai-Tibet Plateau of China. It is difficult to grow for commercial seed production, since seed shattering causes yield losses during harvest. Assessing the genetic diversity and relationships among germplasm from its primary distribution area contributes to evaluating the potential for its utilization as a gene pool...
