Scaffold indicates the location of the corresponding gene in Chlamydomonas reinhardtii genome version 3.0 (http://genome.jgi-psf.org/Chlre3). Subcellular localizations are deduced from the analysis of the protein N-terminal sequence by several prediction programs (Predotar, TargetP, SignalP, and PSORT available at http://www.expasy.ch). The number of ESTs was determined by BLAST alignment of the transcript sequence with NCBI DBest database of November 12, 2007, and supplemented with JGI EST sequences.
