PGPR also produce volatiles that our understanding of plant-microbe interactions. To date, the focus has largely been on plant responses to benefical bacteria. A study in Arabidopsis showed that some puta-tive auxin-regulated genes and nodulin-like genes were up-regulated, and some ethylene-responsive genes were down-regulated, following exposure to Pseudomonas fluorescens FPT9601-T5 [11]. In another study, ric
