Facilitating Growth of Maize (Zea mays L.) by Biostimulants: A Perspective from the Interaction between Root Transcriptome and Rhizosphere Microbiome
The plant growth-promoting
effects of biostimulants have been widely
documented, while little is known about the intrinsic mechanism. In
our study, a pot experiment was conducted to investigate the effects
of biostimulants on maize, and the maize root transcriptome and rhizosphere
microbiome were assessed. The physicochemical properties of the soil
were significantly altered with various trends, and the growth and
yield of maize were promoted by biostimulants. Sampling time and maize
strain were the strongest factors that altered the rhizosphere microorganisms.
Rhizosphere microbiota with biostimulant application exhibited high
community robustness. Root transcriptome analysis suggested an altered
expression profile induced by biostimulants and maize strains. An
integrated correlation analysis demonstrated that phosphate and nitrate
metabolism genes are tightly associated with some rhizosphere microbiota.
These results implied the plant growth-promoting effects of biostimulants
might act in a rhizosphere microorganism-dependent manner and help
to expand the use of biostimulants in sustainable agriculture
