3. 2. The Role of Juvenile Hormone and Ecdysone in Wing Morph Determination in the Wing Polyphenic Water Strider, Gerris buenoi

   University essay from Uppsala universitet/Institutionen för biologisk grundutbildning

   Author : Kevin Nielsen; [2021]
   Keywords : Wing polyphenism; Phenotypic plasticity; Water striders; Gerris buenoi; Ecdysone; Juvenile hormone; RNAi;

   Abstract : In this laboratory study, the role of juvenile hormone (JH) and ecdysone in regulating wing polyphenism was investigated in the non-model organism Gerris buenoi. Topical application of the JH analog methoprene elicited reduced pronotum, wing defects, and nymphal-adult intermediates but no changes to wing morph. READ MORE

4. 3. Investigation of the role of insulin receptor genes in wing polyphenism using gene knockdown and differential gene expression analysis in the non-model organism Gerris buenoi

   University essay from Uppsala universitet/Institutionen för ekologi och genetik

   Author : Sofia Iggström; [2019]
   Keywords : Phenotypic plasticity; RNAi; RT-qPCR; wing polyphenism; water striders;

   Abstract : Wing polyphenism is a type of phenotypic plasticity present in several insect species whereby a genotype have the ability to develop alternative wing morphs when exposed to different environmental cues. One organism demonstrating a clear case of wing polyphenism is the water strider species, Gerris buenoi, which develop long- or short wings depending on exposure to different photoperiods (the time the organism is exposed to light during a 24 h period).
