1-Aminocyclopropane-1-carboxylate deaminase producers associated to maize and other Poaceae species.

ABSTRACT:

Background

Complex plant-microbe interactions have been established throughout evolutionary time, many of them with beneficial effects on the host in terms of plant growth, nutrition, or health. Some of the corresponding modes of action involve a modulation of plant hormonal balance, such as the deamination of the ethylene precursor 1-aminocyclopropane-1-carboxylate (ACC). Despite its ecological importance, our understanding of ACC deamination is impaired by a lack of direct molecular tools. Here, we developed PCR primers to quantify the ACC deaminase gene acdS and its mRNA in soil communities and assessed acdS⁺ microorganisms colonizing maize and other Poaceae species.

Results

Effective acdS primers suitable for soil microbial communities were obtained, enabling
