Abstract Background Ticks are hematophagous arthropods capable of transmitting pathogens threatening human and animal health. The use of individual gene markers has limited phylogenetic studies of ticks, but the mitochondrial genome offers critical data for understanding phylogeny and molecular evolution. Results The mitogenomes of Dermacentor everestianus and Alveonasus sp. were assembled from I…

Abstract Background Partial endoreplication is a prominent developmental feature and poses a significant challenge for whole genome assembly in orchids. This form of cell cycle results in highly unbalanced cell DNA content, with the highly endoreplicated (P) fraction being overrepresented in sequencing data compared to the non-endoreplicated (F) fraction. Results Here, we report the first genome …

Abstract Background The composition of fatty acids, particularly the content of unsaturated fatty acids (UFA), is closely related to meat quality and flavor in ducks. Result In this study, 38 fatty acids were detected in the breast muscle of Sansui ducks, yielding 50 distinct fatty acid composition traits. The results showed that the predominant fatty acids were C18:1n-9, C16:0, C18:2n-6, C18:0, …

Pantoea agglomerans is a Gram-negative bacterium increasingly recognised as an opportunistic pathogen, yet the molecular basis underpinning its host-interaction capacity remains poorly understood. Here, we report the whole-genome sequencing and integrative characterisation of P. agglomerans strain R6, isolated from Lactuca serriola. The 4.7 Mb draft genome (GC content 55.6%) encodes 4,349 genes, …

Cis-regulatory elements constitute a fundamental layer of gene regulation, yet their computational identification has largely relied on transcription factor (TF)-centric frameworks that assume genome-wide background normalization and explicit TF binding models. While effective at the genome scale, such assumptions are less suitable for gene-centered analyses, where local sequence composition defi…

The soil-dwelling Rhabdocoela flatworm, Luticola nematophagus, recently identified as a specialized predator of plant-parasitic nematodes such as Meloidogyne incognita, demonstrates considerable potential as a biocontrol agent for agricultural nematode diseases. This study presents the first chromosome-level genome assembly of L. nematophagus, achieved by integrating PacBio HiFi long-read sequenc…
