Juvenile hormone regulates the photoperiodic plasticity of elytra coloration in the ladybird Harmonia axyridis.

Many animals, including insects, exhibit plasticity of body colour in response to environmental changes. Varied expression of carotenoids, major cuticle pigments, significantly contributes to body colour flexibility. However, the molecular mechanisms by which environmental cues regulate carotenoid expression remain largely unknown.

The complete chloroplast genome sequence of the water fern (Pteridaceae).

This work determined and analyzed the complete chloroplast genome sequence of (Linnaeus) Brongniart 1822 (Pteridaceae). The results indicate that the total chloroplast genome size of is 149,399 bp in length, and the genome contains a large single-copy (LSC) region of 83,580 bp, a small single-copy (SSC) region of 21,241 bp, and a pair of inverted repeat (IR) regions of 22,289 bp. The GC content of is 36.

A dominant variant in DMXL2 is linked to nonsyndromic hearing loss.

Purpose: To explore the genetic etiology of deafness in a dominant family with late-onset, progressive, nonsyndromic hearing loss.

Methods: Genome-wide linkage analysis was performed for 21 family members. Candidate pathogenic variants were identified by whole-exome sequencing of selected family members and confirmed by Sanger sequencing of all family members.

[Rbb4l enhances TGF-β/Nodal signaling and promotes zebrafish embryonic dorsolization].

The TGF-β/Nodal signaling pathway plays an important role in the zebrafish dorsoventral patterning process. To further explore the function and mechanism of this signaling pathway, we identified a set of Smad2/3a interacting proteins by the yeast two-hybrid screen. Rbb4l (Retinoblastoma binding protein 4, like) is one of the identified proteins.
