Transcription machinery

Transcription is the initial step in gene expression. The number of genes or the genome size are not related to the complexity of an organism, but instead the ability to express a particular set of genes over a specific period of time and in different tissues allows organismal acclimatization to environmental changes. For this reason, it is extremely important the study of transcription machinery to better understand the evolutionary process.

We have sequenced several transcripts involved in the transcription process in all the 16 Loricariidae species investigated so far. The table below shows the sequenced transcripts according to their classification. Note the abundance of transcription factors.
