“…Alignment of two D9D genes and isoforms of thirteen other insects revealed D9D genes exist in several highly conserved regions. Four transmembrane domains existed in D9D, suggesting that the sequence spans the lipid bilayer of membranes four times (Kayukawa et al., 2007; Los & Murata, 1998). Three histidine residues in these D9D genes were the highly conserved regions which are catalytically essential in desaturases (Shanklin, Whittle, & Fox, 1994).…”

“…Kayukawa et al. (2007) proved that the expression of D9D increased to enhance the cold hardiness in Delia antiqua through up‐regulating the abundance of C16:1 and C18:1. So far, the same results were seen in S. crassipalpis (Rinehart et al., 2010), A. albopictus (Reynolds, Poelchau, Rahman, Armbruster, & Denlinger, 2012) and F. candida (Waagner et al., 2013).…”

“…Multiple alignments were performed among TpdesatA , TpdesatB as well as the analogous amino acid sequences by DNAMAN. Finally, base on the amino acid sequences of known D9D genes in Lepidoptera and Dipteran from GenBank (Kayukawa et al., 2007), phylogenetic tree was constructed using the neighbor‐joining method in MEGA software with 1,000 bootstrap replications.…”

“…For insects, the D9D gene was firstly proved to participate in cold adaptation mechanisms in Delia antique . In that study, twofold to tenfold up‐regulation of the D9D gene was induced in brain tissues, malpighian tubules, and the midgut when D. antique was exposed to cold (Kayukawa et al., 2007). This same result occurred in Sarcophaga crassipalpis (Rinehart, Robich, & Denlinger, 2010), Folsomia candida (Waagner, Holmstrup, Bayley, & Jesper, 2013), and Aedes albopictus (Reynolds et al.…”

Thitarodes pui larvae have a limited distribution in the Tibetan Plateau and are the host of a parasitic fungus, Ophiocordyceps sinensis. Low temperature is a main environmental stress. However, understanding of T. pui cold adaptation mechanisms is insufficient. Delta‐9‐acyl‐CoA desaturase (D9D) is closely correlated with cold adaptation for many organisms. To further understand the cold adaptation processes in T. pui larvae, two D9Ds, TpdesatA and TpdesatB were sequenced, and expression patterns were investigated during different seasons and cold exposure (under 0°C) in the laboratory. The full lengths of two cDNAs are 1,290 bp and 1,603 bp, and the ORFs encode a polypeptide of 348 and 359 amino acids, respectively. Four transmembrane domains, three conserved histidine residues and five hydrophobic regions exist in these two sequences. The expression level of TpdesatA is up‐regulated in the long‐term cold exposure and negatively correlated with temperature in seasonal patterns. TpdesatB responds to cold temperature in short‐term cold exposure and positively corresponds temporarily in seasonal expression. Two D9Ds may have different substrate specificities, TpdesatA tends to use C16:0 and C18:0 as substrate while TpdesatB prefers C18:0. In conclusion, TpdesatA may play a very important role in T. pui cold tolerance and TpdesatB regulates function in short‐term cold exposure and content change of fatty acids in the body.

“…In insects, Z9 acyl CoA desaturase gene expression has been shown to be responsive to temperature and feeding following starvation. In the onion maggot, Delia antiqua, Z9 desaturase expression was upregulated in pupae in response to cold (Kayukawa et al, 2007) resulting in increased cold tolerance and content of unsaturated fatty acid in brain phospholipids. Further, Riddervold et al (2002) showed significantly increased Z9 desaturase expression in response to feeding in newly eclosed adult crickets following a period of starvation.…”

Cold temperatures are one of the factors influencing color polymorphisms in Acyrthosiphon pisum, resulting in a change from a red to greenish color. Here we characterized gene expression profiles of A. pisum under different low temperatures (1°C, 4°C, 8°C, and 14°C) and durations (3, 6, 12, and 24 h). The number of differentially expressed genes (DEGs) increased as temperatures decreased and time increased, but only a small number of significant DEGs were identified. Genes involved in pigment metabolism were downregulated. An interaction network analysis for 506 common DEGs in comparisons among aphids exposed to 1°C for four durations indicated that a cytochrome P450 gene (CYP, LOC112935894) significantly downregulated may interact with a carotenoid metabolism gene (LOC100574964), similar to other genes encoding CYP, lycopene dehydrogenase and fatty acid synthase. We proposed that the body color shift in A. pisum responding to low temperatures may be regulated by CYPs.
