Using their 1-amino cyclopropane-1-carboxylic acid (ACC) deaminase activity, many rhizobacteria can divert ACC from the ethylene biosynthesis pathway in plant roots. To investigate the role of this microbial activity in plant responses to plant growth-promoting rhizobacteria (PGPR), we analyzed the effects of acdS knock-out and wild-type PGPR strains on two phenotypic responses to inoculation—root hair elongation and root system architecture—in Arabidopsis thaliana. Our work shows that… CONTINUE READING
