Researchers at NUS are tapping HPC resources to gain a deeper understanding on the visual systems of jumping spiders in order to discover how species adapt and diversify.

Visual systems in animals allow them to see and make sense of the world based on light and colours. Opsins, the main visual pigments
found in the retinas of animals, determines their light sensitivity to the world. Studies have shown that lighting conditions can influence the variability of opsins abundance.

Among the invertebrates family, limited available evidence suggests that jumping spiders have excellent vision and are able to detect
ultraviolet (UV) wavelengths as they possess the opsin gene rh3. As such, a team of researchers at the Department of Biological Sciences at National University of Singapore are using whole-genome sequencing of 5 different salticids spiders – Cosmophasis umbratica, Menemerus bivittatus, Phintella vittata, Siler semiglaucus and Telamonia festiva to determine the types of opsins genes that are present in jumping spiders and their light sensitivity in order to offer insights into the genetic basis of the opsins diversification and highlight the plasticity of the UV visual systems.

The team tapped on NSCC’s HPC resources to analyse the RNA and DNA sequences from the spiders and utilised NSCC’s platform to assemble the RNA and DNA genome sequences and run their analyses and generate phylogenetic trees to determine the molecular basis and detect changes in the genomic level of the opsins genes.

The results of this research will provide a cohesive, integrative and multi-faceted understanding of how dynamic underlying gene family evolutions are and ultimately how species adapt and diversify. More importantly, the project will provide multi-level integrative training for postgraduate and undergraduate students in a widely covered multidisciplinary environment of cutting-edge research in life sciences and environmental sciences to support national R&D activities.
