High FPKM values for bacterial genes

Question

[Cacau]

I mapped RNA-seq reads to a bacterial genome and found most genes have a much higher expression level than eukaryotes. Is that due to the small genome size of bacteria?

Answer 1

[Chirag Parsania]

Genome size has nothing to do with gene expression. How do you compare gene expression between bacteria and eukaryotes ? Are you comparing gene to gene (Only orthologous) or you are talking in general ?
