“…Therefore, locusts are attractive organisms for loss of function analyses, as already demonstrated in several studies (Badisco et al, 2011;He et al, 2006;Marchal et al, 2012;Ott et al, 2012;van Hoef et al, 2011;Van Wielendaele et al, 2012Wang et al, 2013;Zhao et al, 2013).…”

“…Thus, the exact functional roles of ACP in locust phase change should be explored. ILP had been demonstrated to act as a vital growth and reproduction regulator in insects (Badisco et al, 2011;Sim and Denlinger, 2013 predicted in C. elegans. Differential expression patterns of these ILP genes are reported to mediate the switch between the C. elegans developmental processes of reproductive growth and dauer arrest (Cornils et al, 2011).…”

“…In arthropods, there is accumulating evidence that peptide hormones such as insulin-related peptides (IRPs) and neuroparsins (NPs) play a crucial role in female reproductive physiology (Badisco et al 2011). The first NP was identified from the migratory locust Locusta migratoria as an antigonadotropic factor that delayed vitellogenesis (Girardie et al 1987a,b).…”

“…The first NP was identified from the migratory locust Locusta migratoria as an antigonadotropic factor that delayed vitellogenesis (Girardie et al 1987a,b). Insulin-related peptides have an opposite effect on reproductive physiology and promote reproductive development (Badisco et al 2011). IRPs and NPs have since been identified in a number of arthropods, including the crab Carcinus maenas and the lobster Homarus americanus (Towle & Smith 2006).…”

The high latitudes inhabited by Antarctic krill Euphausia superba Dana are characterised by extreme changes in seasonal conditions, with very low food availability, long periods of darkness and a massive expansion of sea ice in autumn and winter. How krill adapt to these conditions has yet to be determined, and it was the purpose of this study to gain more insight by investigating the differences between summer and winter krill populations at the molecular level. To achieve this, we used a cDNA microarray to compare gene expression between female adult krill caught during summer and winter near the Antarctic Peninsula (60°S), and between Peninsula krill and krill caught near South Georgia (54°S) during the same winter. The Peninsula seasonal comparison showed up-regulation in summer krill of genes involved in feeding and digestion, respiration, motor activity and immunity. Summer krill also showed evidence of increased vitellogenesis, with an insulin-related peptide up-regulated and neuroparsin down-regulated. The comparison between the different overwintering locations showed an up-regulation in the South Georgia krill of genes involved in feeding and digestion, and immunity. There was, however, no differential expression of genes involved in respiration, motor activity or vitellogenesis, suggesting that despite the above differences, both populations of overwintering krill were in a quiescent state. This study shows how krill physiology changes seasonally at the molecular level and how these changes are flexible according to the overwintering environment.
