“…The CYP3 and CYP4 clans in A. verrucosus generally bloomed in many families. CYPs are inducible under thermal stress (H. Zhang et al, 2018; L. Zhang et al, 2021). A common name for A. verrucosus is the desert ironclad beetle and it is adapted to the Sonoran Desert of the Southwestern United States and Northwestern Mexico.…”

Cytochrome P450 monooxygenases (CYPs) are present in almost all areas of the tree of life. As one of the largest and most diverse superfamilies of multifunctional enzymes, they play important roles in the metabolism of xenobiotics and biosynthesis of endogenous compounds, shaping the success of insects. In this study, the CYPome (an omics term for all the CYP genes in a genome) diversification was examined in the four Tenebrionidea species through genome-wide analysis. A total of 483 CYP genes were identified, of which 103, 157, 122, and 101 were respectively deciphered from the genomes of Tebebrio molitor, Asbolus verucosus, Hycleus cichorii and Hycleus phaleratus. These CYPs were classified into four major clans (mitochondrial, CYP2, CYP3, and CYP4), and clans CYP3 and CYP4 are most diverse. Phylogenetic analysis showed that most CYPs of these Tenebrionidea beetles from each clan had a very close 1:1 orthology to each other, suggesting that they originate closely and have evolutionally conserved function. Expression analysis at different developmental stages and in various tissues showed the life stage-, gut-, salivary gland-, fat body-, Malpighian tubule-, antennae-, ovary-and testis-specific expression patterns of T. molitor CYP genes, implying their various potential roles in development, detoxification, immune response, digestion, olfaction, and reproduction.Our studies provide a platform to understand the evolution

“…In addition, functions of blue pigments have been studied in other aquatic animals and plants. In Sander vitreus, concentration of blue pigments (sandercyanin) was higher in summer than other seasons, which may play roles in countershading and photoprotection [36]. Except for greening oysters, blue pigments produced by Haslea karadagensis showed multiple biological activities, including inhibiting the growth of marine bacteria and fungi and antiviral activity [37].…”

Rhopilema esculentum is widely cultured in Chinese coastal regions and has thousand years of consumption history in China. Despite R. esculentum owns multiple colors (mainly ochre and blue) in aquaculture ponds, little is known about the pigments and color formation. This study identified and verified the blue pigment of R. esculentum. Results showed that the blue pigment of R. esculentum has 262 amino acids with 54.96% identity to the blue pigment protein precursor of Rhizostoma pulmo. The blue pigment of R. esculentum has Kringle and Frizzled domains, which is in accordance with rhizostomins characteristics. Compared to ochre R. esculentum, the expression level of blue pigment increased 3.49-fold in blue R. esculentum. In addition, overexpression of the blue pigment in Rhodosporidium toruloides made transformant cells blue under blue light excitation. Our findings provide knowledge for the blue color formation of R. esculentum and will benefit the color selection of R. esculentum with excellent traits.

Postnatal Wing Morph of Pea Aphids Regulates Hemolymph Trehalose Levels

Trehalose, a nonreducing disaccharide composed of two glucose molecules, functions as a critical energy source in various insect tissues and organs and is the predominant sugar component of the hemolymph. The pea aphid, Acyrthosiphon pisum, exhibits higher hemolymph trehalose levels than other insects. However, the dynamics of hemolymph trehalose levels throughout its life stages remain unclear owing to the challenges associated with obtaining hemolymph from these small insects. Therefore, this study was conducted to quantify hemolymph trehalose levels in A. pisum using a fluorescent trehalose sensor (Tre‐C04), which enhances green fluorescent protein fluorescence through the binding of trehalose to a ligand‐binding protein fused to the fluorophore. Trehalose levels were successfully quantified in minimal hemolymph samples from individual aphids, with measurements spanning from the first nymphal stage to the adult stage in both the winged and wingless forms of A. pisum. Hemolymph trehalose levels remained relatively stable throughout the life cycle but exhibited a gradual increase with each developmental stage. Notably, adult winged aphids exhibited significantly higher hemolymph trehalose levels than wingless aphids. Given that wing morph determination occurs early in the nymphal stage, these findings suggest that hemolymph trehalose levels are regulated post‐wing morph development. Further investigation of the expression of genes associated with trehalose metabolism revealed that trehalose phosphate synthase 2 levels were downregulated in early‐stage wingless adults, whereas insulin‐related peptide 5 levels were upregulated in wingless aphids. These findings indicate that A. pisum synthesizes trehalose during the winged adult stage to serve as an energy source for flight.
