“Tiny Microbe Inside Plankton Has One of Smallest Genomes Ever Found, Redefining Life” — what this page in the network covers. Scientists have discovered a microbe living inside a dinoflagellate plankton that has one of the smallest genomes ever recorded for a cellular organism, blurring the line between bacteria and viruses. The microbe, found by researchers at the University of Tsukuba, acts more like a virus than a typical cell, yet it is a true organism with a minimal set of genes. This discovery pushes the boundaries of what it means to be alive, as the microbe's genome is so reduced that it may rely heavily on its host for survival.
The finding raises fundamental questions about the minimum requirements for life and how organisms evolve to become highly specialized. It also highlights the incredible diversity of microbial life in marine environments, where such extreme adaptations are often found.
