Title: Life at the Limits: Decoding the Stress-Resistance strategies of radiation resistant organisms
Speaker: Célia Romão
From: ITQB NOVA
Abstract: Exposure to extreme radiation doses typically causes severe cellular damage; however, certain organisms exhibit extraordinary resistance to radiation-induced stress. Remarkably, highly radiation-resistant species have been identified across all tree domains of life - Bacteria, Archaea and Eukarya. Our research focuses on the model organism with the highest known resistance, the gram-positive bacterium Deinococcus radiodurans.
In this seminar I will present how a multidisciplinary approach has allowed us to uncover key molecular mechanisms underlying D.radiodurans' exceptional resilience and how these insights are being used for potential applications in bioremediation and in health.
SCANs are weekly seminars that happen every Wednesday at noon by in-house researchers and invited speakers at ITQB NOVA.
