Higher plants have evolved intimate, complex, subtle, and relatively constant
relationships with a suite of microbes, the phytomicrobiome. Over the last few
decades we have learned that plants and microbes can use molecular signals to
communicate. This is well-established for the legume-rhizobia nitrogen-fixing
symbiosis, and reasonably elucidated for mycorrhizal associations. Bacteria
within the phytomircobiome communicate among themselves through quorum sensing
and other mechanisms. Plants also detect materials produced by potential
pathogens and activate pathogen-response systems. This intercommunication
dictates aspects of plant development, architecture, and productivity.
Understanding this signaling via biochemical, genomics, proteomics, and
metabolomic studies has added valuable knowledge regarding development of
effective, low-cost, eco-friendly crop inputs that reduce fossil fuel intense
inputs. This knowledge underpins phytomicrobiome engineering: manipulating the
beneficial consortia that manufacture signals/products that improve the ability
of the plant-phytomicrobiome community to deal with various soil and climatic
conditions, leading to enhanced overall crop plant productivity.
