This supplement comprises a report on progress during 2007-10 on an outstanding and continuing problem. What are effective and high throughput methodologies for validating the function of genes, newly displayed within DNA sequences? The display of genomes as DNA sequence is becoming increasingly cheap and fast. Sequence comparison methodologies do serve for computationally recognizing homologues between genes in a newly displayed genome, with those of previously analyzed genomes. This is a first automated step in annotation of newly recognized, candidate genes. But there are abundant examples that follow through experimentation is needed to improve and often also to correct the first outputs of computational annotation. For newly displayed microbial genomes, about a third of the genes do not thus acquire any functional assignment. For the more complex genomes of higher species, gene coverage by automated annotation is even poorer.
