Dr. Uri Sheyn will present a talk titled "“From Virocells to O cean Patterns\, A Single-Cell View of Viral Infection".\n\n \;\n\n&nbs p\;\n\nTalk Abstract: \n\n \;\n\nViruses play a central role in shapi ng aquatic ecosystems\, yet their impacts are often\n\ninferred from popul ation averages that obscure underlying cellular heterogeneity. In this\n\n seminar\, I present a single-cell framework for understanding viral infect ion across\n\nphytoplankton systems\, from acute lytic infection to viral genome integration.\n\nUsing single-cell transcriptomics and mRNA imaging\ , I show that viral infection\n\nproceeds through discrete cellular progra ms that define distinct virocell states\, providing\n\na mechanistic frame work that links intracellular regulation to emergent biological\n\npattern s. These states rewire host physiology and help explain how infection infl uences\n\nbloom dynamics and vertical redistribution of bloom biomass in t he ocean. I further\n\ndemonstrate that integrated viral genomes in Chlamy domonas reinhardtii exhibit\n\nheterogeneous expression states at the sing le-cell level\, revealing viral strategies that\n\nare difficult to interp ret from bulk data alone.\n\nI conclude by outlining how these approaches can be extended within the Technion’s\n\ninterdisciplinary research envi ronment to resolve how viral infection reshapes\n\ninteractions among micr obes\, linking cellular infection states to community organization\n\nand ecosystem-scale patterns.\n\n \;\n\nLooking forward to seeing you!\nMa ya END:VEVENT BEGIN:VTIMEZONE TZID:Asia/Jerusalem X-LIC-LOCATION:Asia/Jerusalem BEGIN:STANDARD DTSTART:20251026T010000 TZOFFSETFROM:+0300 TZOFFSETTO:+0200 TZNAME:IST END:STANDARD END:VTIMEZONE END:VCALENDAR
