Becoming a worm

Sequencing of the worm genome has allowed Hill et al. to design oligonucleotide arrays representing 18,791 (98%) of the predicted worm open reading frames (ORFs). In the 27 October Science, they report the use of these arrays to analyze transcripts from six developmentally staged worm populations from eggs to adults (Science 2000, 290:809-812). Only 56% of the ORFs are detected at least once, suggesting that others are missed because they are expressed at very low levels in specific tissues or u

Sequencing of the worm genome has allowed Hill et al. to design oligonucleotide arrays representing 18,791 (98%) of the predicted worm open reading frames (ORFs). In the 27 October Science, they report the use of these arrays to analyze transcripts from six developmentally staged worm populations from eggs to adults (Science 2000, 290:809-812). Only 56% of the ORFs are detected at least once, suggesting that others are missed because they are expressed at very low levels in specific tissues or under specific conditions. Aging worms show transcriptional correlates of impaired muscle function, reduced metabolic activity and extracellular matrix defects. During development, expression of genes specific to worms becomes more predominant, at the expense of expression of genes that are evolutionarily conserved.
