Dasycerus occultus Hashizume Maruyama, sp. nov. is described and illustrated based on specimens from Japan (Honshu and Kyushu). The holotype of D. japonicus Nakane, 1963 was revisited. The D. japonicus illustrated by Lbl Calame (1996) was found not to be D. japonicus but rather to be D. occultus sp. nov. The discussion also includes D. poseidon Hu Liang, 2021 from Taiwan. The phylogenetic relationships of this genus from Japan based on mitochondrial DNA sequences are discussed.

The Hepatincolaceae (Alphaproteobacteria) are a group of bacteria that inhabit the gut of arthropods and other ecdysozoans, associating extracellularly with microvilli. Previous phylogenetic studies, primarily single-gene analyses, suggested their relationship to the Holosporales, which includes intracellular bacteria in protist hosts. However, the genomics of Hepatincolaceae is still in its early stages.

Comparative Analysis of Protist Communities in Oilsands Tailings Using Amplicon Sequencing and Metagenomics.

Environ Microbiol

January 2025

Division of Infectious Diseases, Department of Medicine, and Department of Biological Sciences, University of Alberta, Edmonton, Alberta, Canada.

The Canadian province of Alberta contains substantial oilsands reservoirs, consisting of bitumen, clay and sand. Extracting oil involves separating bitumen from inorganic particles using hot water and chemical diluents, resulting in liquid tailings waste with ecotoxicologically significant compounds. Ongoing efforts aim to reclaim tailings-affected areas, with protist colonisation serving as one assessment method of reclamation progress.

Institute of Cotton, Hebei Academy of Agriculture and Forestry Sciences/Key Laboratory of Cotton Biology and Genetic Breeding in Huanghuaihai Semiarid Area, Ministry of Agriculture and Rural Affairs, Shijiazhuang 050000, China.

SKP1 constitutes the Skp1-Cullin-F-box ubiquitin E3 ligase (SCF), which plays a role in plant growth and development and biotic and abiotic stress in ubiquitination. However, the response of the gene family to abiotic and biotic stresses in cotton has not been well characterized. In this study, a total of 72 genes with the conserved domain of SKP1 were identified in four Gossypium species.

Key Laboratory of Cotton Breeding and Cultivation in Huang-Huai-Hai Plain, Ministry of Agriculture and Rural Affairs, Institute of Industrial Crops Shandong Academy of Agricultural Sciences, Jinan 250100, China.

The Really Interesting New Gene (RING) E3 ubiquitin ligases represent the largest class of E3 ubiquitin ligases involved in protein degradation and play a pivotal role in plant growth, development, and environmental responses. Despite extensive studies in numerous plant species, the functions of RING E3 ligases in cotton remain largely unknown. In this study, we performed systematic identification, characterization, and expression analysis of genes in cotton.
