This is an image of a stained Drosophila cell. Scientists from Indiana University are part of a consortium that has described the transcriptome of the fruit fly Drosophila melanogaster in unprecedented detail, identifying thousands of new genes, transcripts and proteins. In the new work, published Sunday in the journal Nature, scientists studied the transcriptome -- the complete collection of RNAs produced by a genome -- at different stages of development, in diverse tissues, in cells growing in culture, and in flies stressed by environmental contaminants. To do so, they used contemporary sequencing technology to sequence all of the expressed RNAs in greater detail than ever before possible.
