What might retrotransposons teach us about aging?

abstract：:Chemoreceptor-based signaling is a major bacterial signal transduction mechanism. Escherichia coli, the traditional model, has five chemoreceptors. Recent genome analyses have shown that many bacteria have a much higher number of chemoreceptors. Pseudomonas putida KT2440 is an alternative model that has 27 chemorecept...
