Jhe in Gryllus assimilis: Cloning, sequence-activity associations and phylogeny

Evolutionary Endocrinology: The Developing Synthesis between Endocrinology and Evolutionary Genetics

“…Enzymatic properties do not differ between JHEs from high and low activity lines, nor are there nucleotide differences in the coding sequence of JHE genes within or between selected lines (Crone et al 2007 and references therein). Cosegregation between line-specific JHE allele and blood JHE activity implicates DNA sequence variation at or near the JHE gene region as a contributor to line differences in blood JHE activity.…”

“…For example, QTL analysis of variation in the corticosterone-mediated stress axis in the rat identified a complex genetic architecture consisting of multiple interacting genetic factors with maternal and sex effects (e.g., Solberg et al 2006). Until very recently, this approach was not often used in evolutionary-endocrine studies, and contributions of individual genes to a quantitative endocrine trait of interest are not well known [however see Crone et al (2007) and Hoekstra et al (2006); discussed below in the sections on Continuous Variation in Insects and on Vertebrate Studies]. We expect such analyses to become common in the next decade.…”

Molecular characterization and functional analysis of novel carboxyl/cholinesterases with GQSAG motif in the silkworm Bombyx mori

“…To date, genes encoding JHEs or putative JHEs have been identified in the lepidopteran species Heliothis virescens (Hanzlik et al, 1989), Manduca sexta , Trichoplusia ni (Hanzlik and Hammock, 1987), Choristoneura fumiferana (Feng et al, 1999) and B. mori (Shiotsuki et al, 2000;Hirai et al, 2002), in the coleopteran species Leptinotarsa decemlineata (Vermunt et al, 1997a,b), Tenebrio molitor (Thomas et al, 2000) and Psacothea hilaris (Munyiri and Ishikawa, 2007), in the orthopteran species Gryllus assimilis (Crone et al, 2007b), in the dipteran species Drosophila melanogaster (Campbell et al,1998(Campbell et al, , 2001 and Aedes aegypti (Bai et al, 2007), in the hymenopteran species Apis mellifera (Mackert et al, 2008) and in the hemipteran species Nilaparvata lugens (Liu et al, 2008). Recently, it was reported that several insects have several jhe-like genes (Campbell et al, 2001;Bai et al, 2007;Mackert et al, 2008).…”

Juvenile hormone (JH) esterase activity but not JH epoxide hydrolase activity is downregulated in larval Adoxophyes honmai following nucleopolyhedroviruses infection

“…The insect order, GenBank accession number, and reference of the sequences are as follows. Lepidoptera: AhJHE (LC012033, this study), CfJHE (AF153367) (Feng et al, 1999), HaJHE (FJ997319) (Teese et al, 2010), HvJHE (AF037197) (Hanzlik et al, 1989), MysJHE (ACO81854), BmJHE (AF287267) (Hirai et al, 2002), MsJHE (AF327882) (Hinton and Hammock, 2001), OfJHE (ACB12192); Diptera: CqJHE (JN251105) (Kamita et al, 2011), AaJHE (EAT43357) (Bai et al, 2007), DmJHE (AF304352) (Campbell et al, 2001); Orthoptera: GaJHE (EF558769) (Crone et al, 2007b); Coleoptera: TcJHE (NP_001180223) , TmJHE (AF448479) , PhJHE (AB259898) (Munyiri and Ishikawa, 2007); Hymenoptera: AmJHE (AY647436) (Mackert et al, 2008); Hemiptera: NlJHE (EU380769) (Liu et al, 2008). because of the production of growth-blocking peptide (GBP) in hemolymph (Hayakawa, 1995). It would be interesting to investigate whether baculovirus infection also induces production of GBP.…”
