Microbiological Mechanisms of Sand‐Mixed Soil Improvement in Continuously Cropped Soil

Land Degradation &Development, EarlyView.
ABSTRACT Sand‐mix soil is a widely adopted method for soil improvement in agricultural production. However, beyond the evident enhancement of physical structure, the mechanisms by which sand‐mix soil promotes crop root growth by influencing soil physicochemical properties and microbial communities remain insufficiently understood.

From the sea to DNA barcode: Optimized preservation method for gelatinous zooplankton integrative taxonomy

Limnology and Oceanography: Methods, EarlyView.
Abstract Assigning taxonomic identity and thus assessing taxonomic diversity in gelatinous zooplankton is challenging due to their fragility and difficult preservation. Formalin fixation compromises DNA integrity, while flash‐freezing, ethanol, and acetone preservation affect morphological features. In this study, we developed a methodological protocol

Phylogenetic analysis of Cryptosporidium isolates from captive reptiles using 18S rDNA sequence data and random amplified polymorphic DNA analys

, 1999
Sequence alignment of a polymerase chain reaction-amplified 713-base pair region of the Cryptosporidium 18S rDNA gene was carried out on 15 captive reptile isolates from different geographic locations and compared to both Cryptosporidium parvum and ...

Molecular Analysis of Pomphorhynchus kashmirensis based on 18S rDNA and ITS-rDNA

International Journal of Zoology and Animal Biology, 2022
Pomphorhynchus kashmirensis Kaw, 1941 was redescribed to correct inadequacies in the original description. We provide a molecular characterization to qualify its now completed morphological description and to compare with related taxa. Sequences of the 18S rDNA and ITS-rDNA datasets of specimens of P.

Amanita theophili sp. nov. (Amanitaceae) from central Mexico

Nordic Journal of Botany, EarlyView.
Amanita theophili sp. nov., a member of Amanita sect. Amidella (Amanitaceae), is described from temperate pine‐oak forests in Morelos, central Mexico. Morphological features and phylogenetic analyses based on ITS and 28S rDNA sequences confirm its distinct taxonomic status. The new species is morphologically similar to A. peckiana and A.

Increased Ribosome Biogenesis and Increased Oxidative Stress in Blood Leukocytes of Patients With Catatonic Schizophrenia Compared With Paranoid Schizophrenia

Frontiers in Bioscience-Landmark
Background: Schizophrenia (SZ) is associated with chronic oxidative stress in the patient’s body. Previous studies revealed an increased copy number of genes for 47S pre-ribosomal RNA (pre-rRNA) in SZ patients. In this study, levels of

Cytogenetic relationships within the Maghrebian clade of Festuca subgen. Schedonorus (Poaceae), using flow cytometry and FISH

Anales del Jardín Botánico de Madrid, 2017
Festuca subgen. Schedonorus is a group of broad-leaved fescues, which can be divided into two clades: European and Maghrebian. We employed fluorescent in situ hybridization —FISH— with probes specific for 5S and 35S ribosomal DNA and genome size ...

Between birch and berries: seasonal dietary niche partitioning among sympatric alpine herbivorous birds

Oikos, EarlyView.
Niche partitioning is important for the coexistence of closely related species, allowing species to reduce overlap in resource use despite shared ecological requirements. In alpine environments, harsh climatic conditions and low habitat complexity constrain opportunities for ecological segregation, making seasonal resource fluctuation especially ...
