The genome of the water strider Gerris buenoi reveals expansions of gene repertoires associated with adaptations to life on the water. BMC Genomics. 19:832.

Interpretive Summary: Water striders have a unique capability to walk on water and have been studied from the standpoint of their ecology and biology. To fully understand the genetics responsible for their adaptation to living on water surfaces, the water strider genome was sequenced and assembled, and genes from the assembly were annotated manually. Expansions of gene families associated with growth, vision, and other critical life processes were found that can explain the adaptation of this insect to occupy a unique ecological niche. These data will enable the coupling of water strider biology with underlying genetic architecture and enhanced appreciation for the factors that contribute to the success of these insects as dwellers of the water surface.

Technical Abstract: Water striders conquered water surfaces worldwide and occupy ponds, streams, lakes, mangroves, and even open oceans. As such, they inspired a range of scientific studies from ecology and evolution to developmental genetics and hydrodynamics of fluid locomotion. However, the lack of a representative water strider genome hinders thorough investigations of the mechanisms underlying the processes of adaptation and diversification in this group. Here we report the sequencing and manual annotation of the Gerris buenoi genome, the first water strider genome to be sequenced so far. Gerris buenoi genome is about 1000Mb and the sequencing effort recovered 20,949 predicted protein-coding genes. Manual annotation uncovered a number of local gene duplications and expansions of gene families known for their importance in a variety of processes associated with morphological and physiological adaptations to water surface lifestyle. These expansions affect key processes such as growth, vision, desiccation resistance, detoxification, olfaction and epigenetic components. Strikingly, the Gerris genome includes three Insulin Receptors, a unique case among metazoans, suggesting key changes in the rewiring and function of the insulin pathway in water striders. Other genomic changes include wavelength sensitivity shifts in opsin proteins likely in association with the requirements of vision in water habitats. Our findings suggest that local gene duplications might have had an important role during the evolution of water striders. These findings along with the Gerris buenoi genome open exciting research opportunities to understand adaptation and genome evolution of this unique hemimetabolous insect.
