An unannotated coding reserve in bacterial genomes?

Dr Zachery Ardern, post-doctoral researcher in bacterial genomics, Technical University of Munich, Germany


Recent work in microbial genomics has discovered multi-faceted, previously unknown complexity in bacterial genomes, including hundreds of small RNAs and unannotated small proteins and pervasive transcription antisense to protein-coding genes.

There is also increasing evidence of a large unannotated coding reserve in many bacterial genomes consisting of hundreds of highly gene-like sequences in a typical genome.

Much of this coding reserve is found overlapping currently annotated genes. Coding overlap is a phenomenon closely investigated in viruses, but seldom considered significant in bacteria.

The evidence for genes or coding reserve with non-trivial overlaps with annotated genes includes strand-specific knock-out experiments, ribosomal profiling, and evolutionary conservation.
