摘要

Photosynthetic organisms come in all shapes and sizes. From a human perspective, the trees and plants of dry land are the most conspicuous examples, but the next time you admire a colorful tulip or marvel at the girth of a giant Sequoia, consider the following: Approximately half of the oxygen we breathe is generated by single-celled photosynthesizers, phytoplankton, adrift in the world's oceans, invisible to the naked eye and unfathomably large in number, quietly harnessing solar energy, fixing carbon dioxide, and producing oxygen by the bucket-load. In this issue of PNAS, Derelle et al. (1) present the complete genome sequence of the smallest of the small eukaryotic (nucleus-containing) phytoplankton, Ostreo-coccus tauri. This organism is best known for its diminutive cell size, about that of a typical bacterium. Its genome is equally remarkable for its small size and extreme compactness. However, the O. tauri genome is also unexpectedly complex and provides a fascinating glimpse into the genetic makeup and metabolic potential of the smallest known eukaryote at the base of the marine food chain.
